Cartrophen Vet. Is it safe?

 Since I wrote this article I’ve received many comments about animals becoming very ill, and some dying shortly after an injection of Cartrophen Vet.  Please check the comments for personal experiences with this drug, and please do the research on this drug first.  There are links provided at the end of the article.

I have years of experience helping sick animals, especially those with cancer.  I’ve learned the best question to ask is what are we putting into our companion animals bodies that is contributing to them being diagnosed with cancer and other serious illnesses at staggering rates, and why isn’t that being addressed as part of treatment.   When I got asked about Cartrophen Vet for treatment of arthritis, I went hunting for everything positive and negative about the product.  What I found was alarming.

Cartrophen Vet is prescribed for patients with osteoarthritis and other joint problems.  What scares me the most about this medication is that it causes unspecific tissue growth.  What does that means to a dog or cat with an undiagnosed mass,  if it’s malignant it can accelerates cancer!  What’s even scarier, veterinarians refuse to associate Cartrophen vet with the many deaths and illness that have been reported within days or even hours after an injection.  Which makes the data from trials and lists of documented side effects on this drug far from accurate.    The risks associated with an animal being given cartrophen vet are seldom explained, vets have admitted not giving specific details in fear of “scaring the patients.”

I don’t believe medication for an animal or person is ever a good idea without first looking at possible lifestyle habits that may  be contributing to the illness.  By just taking medication you are lying to your body that you are well, when in fact your body never got the chance to heal because you haven’t addressed the problem causing the disease.  I don’t say that lightly or without understanding how challenging it is sometimes to find solutions.  Over the years I have had 6 dogs diagnosed with life threatening diseases,  all of them died to young,  and before I started questioning the options given by veterinarians,  the treatment for some of them ended up being worse than the disease.

I have heard of more long-term success with controlling arthritis in dogs and cats with diet changes.  It seems the safer route rather than just creating more difficulties for an animal from drug induced side effects.   When a veterinarian prescribes a treatment many want to believe what their vet tells them, and does so blindly never asking the right questions.  We do need to start to ask more questions,  because many of our dogs don’t live past the age of 7, and there are simple reasons for that.  What quality of food you are feeding your dog,  even from expensive brand names may not be what you think.  Most consumers are not aware that pet food is a convenient way for slaughter houses to turn waste products into profit.

So I asked myself,  did I want this person whose dog is a rottweiler,  a breed commonly diagnosed with cancer,  and considering she is older,  around 6,  take this risk.  Because we often don’t know what is happening in our companions animals bodies,  medication like Cartophen is like playing Russian Roulette.  (Cartrophen vet is contradicted for animals with blood clotting,  thrombocytopenia, traumatic hemorrhage, cancer or infection.  Please be aware of this because vets have prescribed this drug to dogs knowing they have cancer despite this warning.  The last person that contacted me in such a case lost her dog very soon after the initial injection.  In return for her grief  the veterinarian refused to link the dogs death with the drug.)

So what feedback I gave after my research was  if she was my dog,  Cartrophen would not be considered, ever!.   It may take the pain away but it’s no more than a band-aid, which if left on to long leaves an awful mess behind.  I gave him recommendations for the dog’s diet and some natural products to help the girl with any discomfort.  There are so many safe ways to help an animal with arthritis that we need to try first,  so we can enjoy their company without shorting their lives.  The dog is now on a non-grain diet,  within a week she showed improvement,  she no longer needs medication because we eliminated the cause.  My own dog suffered from arthritis.  I was told he would have no mobility in his back legs within a year.  My first step, and the only one in his case that was needed was taking him off grain.  He not only thinks he is a puppy again but the chronic ear infections that we continually battled,  disappeared.  His hair is turning silver,  showing a bit of his old age,  but aging doesn’t mean  he can’t be a healthy and happy dog.  Changing dog food alone may not be the answer for all animals,  but something we need to defiantly look at first.

The best way I can put this in perspective is in a quote borrowed from Paws to Heal. ‘If you don’t look, you won’t see’.  It is time we took off those blinders.

Reference: I’ve tried to provide as much as I can to help you, help your animal.  I have not included recommendations for natural remedies for arthritis.  I believe each animal is different and your best bet is to consult a trusted veterinarian homeopath.

As for research studies, the manufacture say that cartrophen vet is safe and side effects are low. The problem is the manufactures or associates usually are the ones who run the research studies, not an unbiased party. It is difficult to find studies that are conducted with companies unrelated to the manufacture, or pharmaceuticals.  As well, vets often refuse to associated any reported illnesses after  an injection of cartrophen Vet.

This is a data sheet, it states cartrophen vet is contradicted to give this product to dogs with cancer.

  1. Hello,
    I am a Vet and I am impressed with your common sense advice regarding Cartrophen Vet. I would like to cite your article in my own blog post with your permission as I am compiling my own data and information on this subject. You are nine months ahead of me as I have debated whether I should voice my observations.
    I have long regarded cartrophen to be dangerous, especially in older animals which is when it is mostly prescribed. As an Holistic Veterinarian taking referrals of cancer, I am alarmed at the numbers presenting with sudden onset cancer post cartrophen injections.
    In my previous small animal clinic I began to suspect this link when some of my own cartrophen patients developed bone cancers. Since having stopped using the preparation myself I know see everyone else’s patients presenting with the same.
    The most common is osteosarcoma and liver cancer
    When I used to use it in the nineties, it clearly stated on the label of contraindications that Cartrophen Vet should not be used in cases of undiagnosed cancer. As this is a clearly ridiculous comment I am not surprised that it has been amended or removed but the basis for the warning was the capacity to increase blood flow to areas of disease, hardly sensible for cancer. This is still what it does whether the label states as much or not.

      Hello, My silky terrier cross 7kg dog was 17 years old in 2010 and she started having difficulties walking, due to spinal arthritis. It got to a point where her tail would shoot off to one side and she couldnt walk first thing in the morning. I couldn’t stand by and watch it and felt compelled to do something.

      Other than that she was in fantastic condition going for daily walks. Her diet, being looked after and care could not have been better. Since the age of 8 I fed her home made food with supplements including aloe vera extract and fish oil etc.

      I felt that I had a duty to care for my dog before euthanising her as a last resort where pain relief was no longer working. In that position, Cartrophen , amidst harsher NSAIDS like Carprofen , metacam etc, was on balance the best option to try.

      So we did. I must say that my vet was very confident in the safety of Cartrophen.

      Initially, it did appear to help to reduce the early morning seizing up that my dog would experience.

      However, Within a year, around April 2011, intermittent lameness form what we thought was spinal arthritis/spondylosis became regular/constant lameness and visits to the vet for anti inflammatory metacam shots which seemed to get her going for afew weeks.

      In the end, we discovered that she developed osteosarcoma/bone cancer in the front leg at 18. The diagnosis was made by x ray. It was absolutely devastating. At such an old age, most surgical or treatment therapies were off the cards.

      In the very end, euthanasia was the only option, around June 2011. When pain relief stopped working there was only one choice and it had to be made quickly to avert incredible suffering – and in the circumstances of vocal pain and suffering, it was easy to do and there was no doubt the pet was thankful for us sending her to tranquility and freedom.

      My vet seemed fairly sure osteosarcoma/ bone cancer was not from the Cartrophen describing it as ‘safe as houses’ and with no negative reports during his approximately 10 years of practice.

      I must admit I did and do suspect, otherwise. The way the osteosarcoma came out of left field, and took over so rapidly for such a healthy dog was just insane.

      However this is not with a sense of blame for our vet who was very good and helpful throughout.

      After all, at the age of 18, anything we did to relieve pain could have had side effects and it was clear we had to do something for her when she started limping severely in the mornings. It was really a question of how do we manage side effects and conditions to achieve comfort for the dog.

      Nonetheless, even 8 months after it all ended, the suspicion that Cartrophen may have been to blame or an accelerating factor has me still researching the proposition and hence me reading this blog, partly out of guilt, but also curiosity and genuine interest.

      There can be a problem with forums like this, and that is that the real scientific data and considered scientific observation is lacking, and we can jump to unjustified conclusions. That is something to keep in mind.

      In any case, my take as an animal lover who has been down this road is consistent with that espoused elsewhere on this page- that you should always try the natural remedies exhaustively to see what works before going for the man made remedies. The amazing system of the living body must first be assisted naturally to heal itself rather than to impose potentially dangerous chemicals that really only act as temporary band aids.

      In any case, there are no easy answers, and the sooner we realise that there is only so much we can do to slow the sands of time in each of the hourglasses that are the lives of ALL living beings , the better we can be prepared , and further deal with the battleground of ailing health. In doing so we will also come to fully and completely understand and live the true gift of love these creatures teach us – in their bodies, and then in spirit, still with us, when they pass on.

      This is a great site for animal lovers dealing with mobility issues in pets. Good luck to all visitors and readers trying to assist their much loved pets.

        I’ve just had my 13 year old Rhodesian Ridgeback injected with Cartrophen – she has been an extremely active and healthy dog until about 6 months ago, usually lapping me off the lead when we walk up the mountain behind where we live. At 13 she is old. When I got her, the breeder told me, in terms of her expected longevity, that “with Ridgebacks (which are big dogs), anything over 10 is a bonus”. So really, we’re in bonus territory here. Since her cartrophen shots, she has been happy and active – able to go for walks again. She has a new lease on life. Before the injections she had gotten to the point where she hardly moved. Though I understand how cartrophen might encourage any cancer already starting off in an older dog, surely this should be weighed up against the benefits it is providing in terms of quality of life for dogs that are in pain especially when they are living on “bonus time”. It sounds to me like your dog was very old, and as with my dog, was living on bonus time. The cartrophen improved her life, albiet briefly. How long did you expect your dog to live? Did you want her to suffer in her old age? Taking medication should always involve a risk/benefit analysis. If my lovely old girl develops cancer in the next year/6 months, so be it. She will have had some extra quality of life in her last year.

      Would you be able to share any of the information that you have on cartrophen? I believe my dog died because of it but the vet said it was just a coincidence.
      Thanks

        Hello there, I dont have much information unfortunately.
        You can try researching through search engines. In my case I didnt have much option but to try something or have the dog lose all mobility. I would not try to blame the vet and be open to his opinion. After all, their livelihood depends on a good reputation and referrals, generally speaking they would not be quick to do something that would endanger your pet for commercial expediency.

        My dog also died after a catrophen injection, it was a horrendous experience 4 hrs after the injection. Although he had 3 injections before that with no effects but good results. We are left wondering why he died after that particular injection. The vet has not rung us to offer any advise obviously.

        I am so sorry to hear this, I really don’t know amything about this drug except from what I have read, I wouldn’t let my cat have anymore, he had 1 shot before I knew how dangerous it wasand told the vet that I wasn’t letting him have anymore. I hope you get the info you are looking for.

  2. Thank you for your reply, feel free to cite anything that may help you.
    Just an update on the dog mentioned. The owner changed her diet to grain free, and the improvement was seen within in a week. She is pain free and a happy girl, this required no use of medication. This may not be the answer in all cases, but it’s alarming vets offer medication without looking at what is going into the dogs body first, and how that can be a contributing factor to both the problem and solution. This is no different from how medical doctors treat most problems, in both animals and humans.

      I researched everything on the Net before giving this drug to my 12 1/2 years old pure Boxer. I was so scared about all the negative comments. Before this drug, I have tried rimadyl combine with pain killer and still he was in pain. Anyway, I don’t work for the pharmaceutical company, I just want to say that Boogie has been on Cartrophen for 8 months now and he is jumping like he is a puppy again and anyone who know Boxer know what I am talking about. Yes, maybe this drug is not for every dog but for me, it has been a savier. My old boxer is running again. As I am writing this, he is close to 13 years old for which I understand is very old for a Boxer. Lifespan is more like 10-12 max. So far everything is ok. Anyway, here is my email if you want to talk about it. marc-rrt@hotmail.com. Again, I don’t work for any pharmaceutical, just wanted to give my own experience. Feel free to contact

    Hello, being the stupid human I am, I too recently gave in to my Vet’s instructions to start my German Sheppard “Armour” on Cartophen. I did notice a slight improvment however, not long after the series of injections she developed breast cancer. One day she was fine then the next day this lump had appeared and thats literally how fast it was. Fortunately I’m very hands on with her and I discovered the lump quick enough to have it removed. I didn’t suspect that any of the choices I’d made could be the cause until now. I’ve just started researching cartrophen and it’s alarming how many other pets have experienced the same or similar side effects. I’m horrified to say the least. Can you tell me what changes I can make to her diet and lifestyle to ease the discomfort that Arthritis is causing her. She’s a beautiful girl and at 11 years old, I think she’s doing wonderfully. Forever grateful. Renae

    • Thank you for your comment Renae

      No one is stupid, sadly many of us are uninformed and mindlessly trust vets and doctors, but realistically be should be able to trust their word. My experiences come from trusting vets, then finding out better choices could of been made, and/or the animals life was lost prematurely because of the treatment offered. Being informed is the best answer I think to helping our companions live longer, happier lives.

      I am not a vet, so my advice is based on research, including questioning both conventional and homeopath vets on issues that concern us. What I have found is the highest contributing factor to many illnesses in dogs, especially arthritis and ear infections, is the food we feed them. Most of it is processed, many contain ingredients that are carcinogenic and most of it includes bottom of the barrel meat by-products. Many dogs also have sensitivity to grains, removing them has produced very good results in dogs suffering from mild to moderate arthritis. That is what I would recommend for your girl. I would also encourage you to find a homeopath vet close to your area. I have found there are only a few to chose from, and usually you need to travel. The extra cost of a homeopath and the trip, is paid back by not having to return as often because of further complications, as you may find when conventional vets prescribe treatments.

      Switching to grain free has to be done very slowly. I started by going for a low grain, high quality organic food to start, 1/4 cup replacement a day, and noticed differences within a week. After removing my own dog from a grain diet, he is a 8 year husky who now can run and play, without coming in limping and in pain as he did prior to his diet change. His chronic ear infections have also vanished. Amazing how something so simple as diet change can effect our companions. Overall he is just a healthier, happier dog.

      There are also Chinese herbs that can help your girl with any discomfort. Prescribed by a homeopath vet, these are given specifically to suit the symptoms, it isn’t a general pill or liquid they give all animals, so the more information you can give them the better off she will be.

      I hope I’ve helped you and your girl. If you decide to change her diet, or visit a homeopath I would appreciate an update.
      Good luck and Happy New Year.

    Hi I have a young Irish Wolfhound butch. 22 weeks old, hand reared from 2 weeks due to damage in left leg joint. Initial x-ray showed infection and a gap in the elbow joint. Antibiotics , long course have cleared the infection and further x-ray shows she has grown into her joint. She will always have some limp but recently she must have knocked the elbow causing pain. She wa placed on an antiInflamrory painkiller which has worked ( not metacalm) and she was ok for a bit. The limp has came back and the vet has suggested cartophen as the x-ray seems to show cartilage damage and he thinks this will lubricate and forestall the onset of arthritis which will become a problem for her. My concern is she is a very young bitch and still growing. One of the contra indications is that it should not be used in youn undeveloped dogs. So I would say she couldnt get the treatment till after 1yr poss longer. I don’t want her to be in pain. During your research has anyone heard of this being used in such a young dog? At present she in on puppy food 3 times a day but we will be getting het onto Nature Diet as it is not made from the off cuts and scraps of meat.

    Reply

    • In my research I haven’t come across age related testing, other than in older dogs who have undetected cancer at the time of treatment. I do know one of it’s uses is to stimulate lubrication of joints. I’ve included a link to a good study done in the UK on the product. Have you considered a homeopath? They treat not mask the problem. I would first check natural options before any drug, especially one so young.

      Best Wishes for you and your dog.

        Reading up on Cartrophen, it does indeed treat the problem. Asprin, or an NSAID ir other painkiller would mask the problem. Homeopathy has not been scientifically proven to help with humans, let alone animals. So it would probabaly do nothing at all. If you want to go the alternative route – the only “alternative” treatment that has had any noticeable results in double blind studies is accupuncture.

    I am very alarmed by the comments I have been reading on the web about the possible connection between Cartrophen and cancer. Our cat, Lily, was recently prescribed a course of 4 weekly injections of Cartrophen for her arthritis. When I took her for her final injection last week, the vet announced that Lily has developed cancer of the lymph nodes in her intestine! (just a month earlier the vet found no sign of this when she examined her). We are devastated by this news and Lily has just undergone extensive (and very expensive) surgery. They were not able to remove all the tumours and we are awaiting lab results before treatment is prescribed. We were not told that cancer could be a side-effect of Cartrophen and I would never have agreed to her having the injections if I had known. I feel very let-down.

      P.S. Update on Lily (above):

      The results from Lily’s operation showed that she had several Leiomyosarcomas in her intestine, one was very large (the size of a walnut). The vet was able to remove some but not all of them, about 3 small tumours remain. Lily was given about 4 months to live in August last year (2011). I am very happy to report that so far (I am currently writing this in February 2012) Lily is showing no signs of ill health at all. Her appetite is good and she is back to her normal self. She is examined by the vet every 4-6 weeks and the remaining tumours have not grown in size at all. We are so relieved and although we have no idea how much longer this happy state of affairs will last, we look on this period as bonus time and we thank God every day she is with us.

      • You are both blessed. Thank you for Lily’s update. I hope you have many days left with her.

      • Posted by Sarah Ballingal on July 9, 2013 at 4:53 pm

        Sadly, we had to say goodbye to Lily today. After nearly two years of ‘bonus’ time with her since her initial diagnosis in August 2011, the tumours in her intestine had started to rapidly increase in size. She died peacefully at home when the vet came to administer the necessary drug. We are so very sad but so grateful for the extra time we have had with her.

    My 11 year old dog was diagnosed with a malignate anal tumor. I did not want chemo or surgery. My vet told me he had 6 – 9 months to live.I elected to take him to a holistic vet. In the course of prescribing natural herbs for the cancer, she recommended Cartophen Vet for arthritis. The dog was not showing any pain from arthritis but was stiff first thing in the morning. Five days after diagnosis of cancer he had the first cartophen injection. Three days later he stopped eating. He had always had a great appetite. He had a second injection 6 days after the first. He collapsed at the vets after the second injection. Two days later we put him down. My conclusion: if your pet has cancer – do not give them cartophen vet.

      So sorry to hear. My husky had first cartrophen injection last wed. Last year,she had surgery to remove a cancerous tumour on side of neck. Now I am seriously worried what to do. My husky is 14 and has arthritus. Should refuse further injections. she has been on k9 immunity and transfr factor to fight any potential undiagnosed cells in herbody. Urgent any advise wuld be really helpful

      • Hi Laura

        With a history of cancer I don’t know if I would be willing to take the chance. This drug can speed up cancer cell growth, if she is still fighting this disease it may be to much for her body to handle. Have you spoken to a homeopathic vet? There are plenty of remedies for arthritis that may help your husky, and not have the potential side effects of Cartrophen Vet. Since I am not a vet, but have spoken to many and done a lot of research on this medication, I can tell you what I would do and that is not take the chance unless all other roads fail.
        I have not read anything negative about K9 immunity, but I see no results in it being used a long side Cartrophen vet, so not enough evidence to ensure us this is an adequate defense against this drug.
        She must be a strong girl Laura, 14 years old, cancer surviver. You’ve done a fantastic job. I’m sure the choice you make for her will be in her best interest. My prayers are with you both.
        Any feedback on what you decide and the outcome would be appreciated. I refer with vets still on this subject and the more information we get the more we can help others.

  7. Thank you so much for sharing your story. I am so sorry for your loss. I hope his death help save others from losing their dog to this drug.

    Please read this article from a Holistic vet on cancer that supports my findings, and is painfully aware of how many pets are diagnosed with cancer after being injected with this drug.

      Hi I went to my vet today for a checkup and we are discontinuing cartophen. I also did some of my own research and found the msds for cartophen vet. It says not to give to pets with tumours and cancer and other abdominal problems I told my vet about the msds today. Because my husky has had cancer two tumours removed over last two years. potentially this drug could have catalysed dorment undiagnosed cells. I am hoping that k9 immunity will continue to resist any potential devt of cancer cells. I will continue to give dha fish oil, synflex for dogs, greenlipped mussels daily to help her reduce osteoarthritus pain. She still loves her walks and walks well for a 14 year old. She also takes milk thisle once a week for keeping her liver strong.

    Hello,
    I had an 11 year old yellow lab.He started drinking a lot of water so I took him to his vet. I was thinking diabetes but it turned out to be cancer. He was expected to live 6 to 9 months. His only sympton was the thirst. I elected not to do surgery or chemo but switched from his life long vet to a holistic vet. I wanted his remaining time to be as comfortable as possible and not bombard his body with chemicals. The holistic vet did an exam and recommended $900 of pills and cartrophen. Although my dog was slowing down he had never been treated for his hips other than with Cosequin. I switched to a grain free dog food and he was wolfing it down. Long story short – he had difficulty standing for a short period after the first injection. After the second he stopped eating and was dry heaving and could barely walk. 10 days start to finish and he was dead.
    The holistic vet believes his rapid demise was due to the cancer.

    • I am very sorry for your loss.

      Let me explain what the major obstacle here is by sharing a story of what I recently went through after a vaccination injection was given to my son, the problem is universal as you will see.
      I took my six year old in for a check up, and was told by the doctor, actually made to feel like I was neglecting my child if I didn’t give him a certain vaccination. I don’t have anything against vaccinations, I do however have a problem with them using thimerosal. It acts as a preservative, vaccinations can be manufactured without it, but isn’t available in large quantities. The vaccination containing thimerosal is not recommended for kids 6 and under, it has potential for neurotoxicity, my son already has a neurological disorder but the doctor insisted, she said statistics show a very low side effect rate, to this drug so I caved, we all want to be good parents to our children, and to our animals. Later I discovered that the doctor was supposed to keep my son in the office for monitoring after the injection for a possible allergic reaction, this wasn’t done. No less than 10 minutes later he started complaining he was dizzy and his head hurt. I honestly thought it was stress form the shot, I left the office and went home thinking he would be fine. By the time I got home, about a forty-five minute drive, my son had a temperature over 104.F, a migraine headache, and disoriented. I called the doctor, her response hit me like a ton of bricks. I was told he couldn’t possibly be having a reaction to the vaccination, he must be ill with something else! How many times have I heard those same words from vets as well! I called back later to tell them his temperature had increased again, he had also went into a crying fit and urinated himself. The doctor told me to give him children’s Tylenol and if his temperature goes over 105 F take him to the hospital. She also insisted again that him being ill was no way related to the vaccination. Do you see what the problem is, because even on our government website that references these vaccinations lists all his symptoms as being side effects, yet the doctor refused to acknowledge it. That leads us directly to that low percentage statistic of side effects to the vaccination the doctor told me before the injection. If doctors or vets aren’t reporting the calls they get from parents of children and animals who have suffered a reaction, how can the information about the drug be trusted, most doctors will say the illness is unrelated to the drug. Doctors also have a talent for making you feel as if you are neglectful, if you don’t support giving the medication they recommend. I’ve been in situations when I’ve taken an animal for two or three opinions on an illness, it’s like they are all reading off the same script, giving the same answers, recommending the same drugs. With Cartrophen vet, I wonder how may more animals have died as a result of being given this drug, not reported because vets refuse to connect the two together. It all comes down to disclosure really, and letting the animals companion make an informed decision, but is that being done.

      The best way I can put this in perspective is in a quote borrowed from Paws to Heal. ‘If you don’t look, you won’t see’.

      http://pawstoheal.com.au/curing-cancer/

      As for research studies, the manufacture says that cartrophen vet is safe and side effects are low. The problem is the manufactures usually are the ones who run the research studies, not a second unbiased party. It is difficult to find studies that are conducted with companies unrelated to the manufacture. I have included links for your reference.

      This is a data sheet, it is contradicted to give this product to dogs with cancer.

      In 2013 all doctors will be made to disclose kickbacks, bonuses, incentives they get from pharmaceutical companies. Something for all to think about. Below are two articles of interest on this subject, most information is hidden but it can be found.

    Thank you for your reply. I’m sorry that you had to go through that with your son. I know how helpless we feel when our children are ill or in pain. For me, I felt that I had contributed to my dogs death by not doing the research myself. The links that you provided are very helpful. Thank you for taking the time to help in my research.

  11. If you did the research before his injection you would of read about studies conducted showing 80% success rate, with very few side effects. My argument is, how are those statics accurate if most veterinarians will not report instances of illness and death after a recent injection, denying the two are linked.
    Jane, I don’t know why your vet treated him with a drug contradicted for animals with cancer. I was going over this for hours last night, researching to find anything that would give him cause. I can not find any. What was he thinking!! I know how difficult it is after you lose one of your family, and you don’t want to continue revisiting the pain. Respectfully, I would encourage you to write Your Veterinarian Medical Association, giving the details of what happened to your boy. They have no choice but to investigate. You can reference any story shared on this blog. Also there is a vet at “Paws to Heal” that wrote an article “Curing Cancer,” that links cartrophen vet to cancer.
    What ever your choice, thank you for sharing your story, you may help save a dogs life.
    If I can help further, please let me know.

    Hi, my story is slighty different from others in the symptomology our dog experienced after the C injection. Our 11 year old blue heeler cross dog was taken to the vet because we noticed a lump on her abdomen. The sample showed that it was just fatty tissue, but the vet said he noticed that her arthritis was worsening (I dont doubt his
    diagnosis), so he reccommended commencing the C injections. My husband agreed
    and she had the first injection that day.
    Later that evening I noticed her limping(which she had not being doing prior), and commented that the injection appeared to be making her worse. We thought no more of it really except that she was limping. We mentioned this at the next appointment for the injection and it was noted but the injection given.
    Again, she seemed to get worse, and the night before the third injection was due I noticed her bump into the wall on her way to the food bowl.
    Next day at the appointment I mentioned this to the vet and said I wondered if this was coincidence, if she had a reaction to the previous injections or if she might have diabetes as that affects the eyes. He tested for diabetes and did not give the next injection, instead he put her on an anti inflammatory liquid – Metacam, with instructions and another appointment within a week to review.
    I took our dog home and two nights later she was totally blind.
    I took her back to the vet early the next morning, a different vet saw her, examined her eyes and explained that whilst totally blind (with no reaction to light whatsoever), there was nothing wrong with her eyes and it must either be the optic nerve or brain. He said that he did not believe in coincidence and that our dog may have had a reaction to the C injection but that it was unlikely and her particular condition was an extreemly improbable reaction.
    He suggested we treat it initially as an optic nerve issue (optic neuritis), as that would be more likely and able to be treated, until he could get in touch with the specialist and make an appointment for us. Wewere to have a review in 5 days.
    Our dog commenced Prednisolone (it is horrific for people too), and experienced the side effects; increased appetite, thirst and urination including some incontinence, rapid breathing and anxiousness – although the blindness obviously contributed to this.
    We returned to the vet, who noticed some response to light in her eyes which he thought might be due to the prednisolone, and suggested our dog remain on a decreased dose but we received a phone call re the appointment with the animal eye specialist and instructions to cease the prednisolone.

    We are waiting on that appointment – 18 April 2012.
    I have no idea what has caused the blindnessor if it is permanent but, like most of you, I have a concern over coincidence and want others to know about a very different symptom from cancer. Sorry for rambling

    • Hi Rhonda

      Sorry it took me a while to reply. I wanted to do some research on the relationship between cartrophen vet and blindness. The chemical make up of Cartrophen vet is 100mg of Pentosan polysulfate (elmiron) and Benzyl alcohol .01mg. On the list of side effects for pentosan polysulfate are, Conjunctivitis, tinnitus, optic neuritis, amblyopia, retinal hemorrhage.
      There is a lot of information on pentosan polysulfate that I’m trying to put together to get a more accurate list of possible side effects. This task has proven to be quite complex. I hope this bit of information I can give you at the moment helps in some way. It’s heartbreaking to hear what you and your girl are going through, and scary that they continue to load her up with harmful drugs as they scramble to find answers. It seems more logical to ask if the blindness will reverse itself after a period of time, more drugs are unlikely to give her back her eyesight only do more harm.
      Your concerns are right on! Please let me know how your appointment goes. Would you consider getting a opinion from a homeopath? They treat her whole body, with no side effects. Strong bodies can heal, by adding drugs we weaken the immune system the body fights the drug and not the problem causing the illness.

      You both are in my prayers.
      Blessings

      Kelli

    I should have read this article sooner. My husband & I had a beautiful rottie x ridgeback who was like our own child. He was 10 and he was put to sleep just this noon due to bone cancer so its a very hard time for us now. Last January we went for his annual vaccination then vet recommended Cartrophen. We blindly agreed since we wanted him to be as he was before. Then like many of you, a lump grew suddenly in his right paw after the third injection. We had it amputated just to be able to spend more time with him as normal as possible. But after 2 months he deteriorated until we ran out of options.
    Thinking about it we suspect that cartrophen may have been a factor. I researched and stumbled on this article and now I’m convinced.

    • I am so sorry for your loss. I have been there many times and have had two rottie’s pass away from the same cancer.
      I’ve had so many people contact me about this drug, and my blog isn’t big so unfortunately it’s not easily found. I am researching the drug in cartrophen vet and putting together information that I plan on giving to the manufacture. I will do my best to try and get the links to this drug and cancer be recognized, so there is full disclosure on side effects then people can make informed decisions. We all want to do what’s best for our fur kids, it’s so hard to know what that is many times.
      Thank you for sharing your boys story.
      Prayers of strength to you and your husband at a difficult time.

    My labrador had a cartrophen injection on 20th december last year. Seven days later she had a massive bleed and needed 3 days at the vets to save her life. Turns out she was limping because her cruciate ligament was beginning to tear not because she had arthritis. She went lame then had a TPLO operation to fix her leg 3 weeks ago. She was doing fine but then had a relapse. She wouldnt eat and couldn’t pass stools. She died on saturday morning ( 21st july 2012 ) I read this forum and wish i could turn the clock back and not give her that injection. She was only nine. I will never forgive myself. John

  20. Hi John
    I am very sorry for your loss, it breaks my heart every time I learn another loved companion has died because of cartophen vet.
    Her death is not your fault, you did everything you could for her. It is the system that allows veterinarians to prescribe medication without disclosing full side effects, and report those side effect to the company so we can have accurate statistics to base decisions on that is at fault.
    What I’ve learned reading people’s stories is that knowledge is key. Share this article. I make no money from this blog but stories like yours can hopefully help others.

    John I here you and feel your pain. We took our Lab(10yrs 9 mths) to the vet May 26 2012as her back leg was shaking. Vet said arthritis so she had her first cartrophen injection, on the 3rd injection she collapsed at the vet now lame in the front leg also. On the 9 July 2012 I lost my girl we had to euthanise as she had a ruptured spleen tumour. Was it there before? Maybe but I do believe it was the Cartrophen that took her life. Yes I feel guilty and heartbroken but I cannot blame myself its the vets and other associations for not declaring the issues this can cause. She will be in my heart forever.

    Hi everyone.
    My 12 year old girl had her first C injection 6 days ago. It was recommended to her when I popped into the vet after she ate something weird at the beach and I wanted to check she was ok. Having found nothing wrong with her and I suspect to cash in on my visit, the vet suggested I start her on C. I supposed she was starting to get a little stiff and bumpy looking, but I really didn’t think she was showing dramatic signs of arthritis onset. Anyway, I sit here now contemplating whether to complete her course. My gut (and now this blog) tells me ‘NO’. What I am worried to the point of tears about is what damage I may have already done. Could one shot trigger cancer? She seems absolutely herself. Perhaps the only unusual occurrence since the shot is that she wet the bed for the first time EVER out of the blue about 3 days after the first shot. Could this mean anything? Nothing since though. If anyone has time to chat for my peace of mind, please write in. This dog is my life. I am cancelling the vet appointment this morning for shot number two, and will begin research into vet homeopathy for future reference. Thanks for listening. xxx

    • Katy I have always found going by our gut instinct is the best way. I’m not sure why your vet prescribed this drug, doesn’t seem justified other than the need to increase your bill. Get a second opinion, a homeopath is a great idea! I’ve researched this drug in great depth, it will never be my choice for any treatment under any circumstances. I’m so glad you decided to explore other options. She certainly sounds like a strong healthy girl in no need of this drug.
      What can one shot do? Depends on the dog. Though stress can be very hard on both of you, and bring down both your immune systems. If you are concerned possibly consider a wellness in the near future for her.
      Breath.
      Please share back how she’s doing.

      I can’t advise you specifically but our cat had 3 injections (out of a course of 4) when cancer was discovered in her gut. She had an operation and thankfully, is still with us over a year later, even though there are tumours still present. I wish I had never allowed her to have cartrophen.

        Thank you so much for your prayers, God has really blessed us with extra time with our Lily :)

        They discovered the cancer when they examined her during the course of the cartrophen injections. They gave her a general external examination prior to starting the course and found nothing, then just 3 weeks later, the vet felt several lumps. They operated immediately but were only able to remove the larger ones (tests showed them to be Leiomyosarcomas) They had to leave 2 or 3 inside her to avoid removing too much of her gut. She is currently examinated every couple of months but so far, the remaining tumours haven’t grown and she is in excellent condition. One would never know that she is ill.

        At the time of the operation, I complained to the vet that I had not been warned of these possible side-effects to cartophen and although she was very sympathetic and contacted the drug company, no connection between the cancer and the cartrophen was acknowledged or confirmed.

    I had my siamese cat to the vet today because he was holding his paw up all the time, they took xrays and she said he had arthritis in his elbow, he is going to be 6 yrs. old im March, he had the 1st needle of cartrophen today and supposed to have 3 more , one a week, but after reading all these comments I am calling the vet tomorrow and telling her I don’t want him to have anymore. She also put him on synovial flex gel… I wasn’t told of all these side effects, All she mentioned was that he would need periodic blood work.

        Skai is on synovial-flex, it is a gel and I put it in his food but he doesn’t always finish the food so I don’t know oif he is getting enough of it. Where do you get the tablets you mentioned? I an going to the vet tomorrow and tell her that I don’t want him to have the other 3 shots. He was fine when I left to do some shopping last Friday and when I got home he was limping and holding his paw up, she took a xray and said he had arthritis, but how can it come on that fast? He is only 5

        Hi, Beverly – I get Lily’s Glycoflex from the vet, it comes in small fish-shaped chews (dose is one per day) which Lily scoffs down with her breakfast! If Skai doesn’t always eat all his food, you could give him the gel/tablets in a smaller portion while he’s still hungry and then give him the rest once he’s eaten the medication. I think you’re wise to stop the course of cartrophen injections, given the chance again, I wouldn’t let Lily have them again.

      • Posted by beverly billard on October 17, 2012 at 6:19 pm

        Thanks for the info Sarah… I’ll keep you informed as to how he is doing… he is quiet now but still playful and eating ok (except when he knows the synovial flex is in his foord) but he is eating his hard food ok… I just feel like I had my feisty boy when I left the house to go shopping and came home to a completely different cat. He had some problems with the paw on that foot when he was declawed and the vet we had then told me that it probably feel numb at times, now I am wondering if that is the case now or maybe he stubbed it somehow,,, he may have the beginnings of arthritis but Idon’t see how it came on within a hour of my leaving him to go out….. Just my thoughts….

  25. Posted by beverly billard on October 17, 2012 at 10:16 pm

    Sarah, I went to the vets and told her I was not going to let Skai have anymore of those needles…. she said I shouldn’t believe everything I read on line and I told her that there were posts from vets as well… I asked for the Glycoflex and they don’t have it, told me to go to a pet store to get them. I went to both pet stores here and they don’t have them either, one girl went on line and said they are only available thru a vet… so I am going to keep looking… I live in Canada and alot of things that are available in the USA we can’t get… the one pet store did have something but it didn’t have the green mussles in it, it had shark cartliage but it was alot strongrer than the gel I got from the vet, and cheaper lol Anyway, I feel alot better knowing I am not doing anything to harm him Thanks again!

      Last year my cat had one shot of the cartrophen, then I read it causes cancer and wouldn’t let him have any more, I posted my fears on here and got alot of nasty comments back from people accusing me of not giving my cat proper care ect. I also stopped letting him have the shots for fleas and went with a natural remedy called Fleatreats, which I order from California and he hasn’t had fleas for nearly 4 years now. The reason the vet wanted him to have the cartrophen was FOR arthritis….I think everyone who has a pet should ask more questions about the treatment the vets are giving their pet. there are ones only interested in the money and care isn’t cheap!

  29. We lost our 7.5 year old rough collie female within a week due to Cartrophen. We didn’t know she had cancer and also she was showing signs of mobility problems. The vet thought she had a knee injury so due to a BAD diagnosis (prescribed Cartrophen) our dog suffered horribly during her last couple of days losing all mobility in her limbs. If your dog has any of these signs please see a proper vet right away. Also get a blood test done if there is any doubt and then you will know about cancers.

    About 9 months ago we started our 11yo Yorkie on Sasha’s Blend as we noticed he was a bit stiff when he first got up in the mornings. About 3 months later he did his cruciate ligament and the vet told us he needed a 4 week course of Cartrophen to “reduce the onset of arthritis”. While he was still in his 8 week recovery from the surgery, the hyperactive little bugger did the cruciate ligament in his other leg…….yep, more surgery and more injections. Now I have received a reminder letter from the vet saying that he is due for cartrophen booster injections (another four week course). Firstly, I was quite annoyed as we were not even told 6 monthly boosters would be needed. Second, I don’t think he even needs them!! He now has a mostly BARF diet and his daily dose of Sasha’s Blend with his dinner. The vet told us following the surgery he would not be able to use stairs or run around any more (try telling that to a dog who thinks he is still a puppy…) but I am not noticing any stiffness in him and he always tries to run around with our other dog (1 1/2 yo Westie) when he thinks no one is looking. After reading all the coments here I think we will just continue as we have been and ignore the letter from the vet.

    Our 15 yr old cat started losing weight last Christmas (2012). The vet did blood work and told us it was the thyroid. We weighed the options, and decided to go with the medicated food, Hill’s Perscription Diet y/d. We noticed since then that he was having a hard time getting around, stiffness in his rear end, worse after waking. We took him in, and the vet said it was either a tumor in the spine, or arthritis. She said she could rule out a tumor with an x-ray, but as there isn’t a treatment that we would put him through in that case we decided to treat it as if it was arthritis. She recommeded C injections, because any medications might conflict with the medicated food and might put his thyroid or kidney at risk. She said that with the 1000’s of dogs and 100’s of cats she’d treated with C injections she’d never seen a significant negative side effect.
    Then I came home and looked it up…
    So I want to know if the medicated food is causing his symptoms of arthritis, or can that food cause cancer? And since it is his controlled diet that is keeping his thyroid good, how can I treat the arthritis with diet?
    Thank you for this post, I already knew about the games pharma plays with meds/side effects for humans, not a surprise they do it on our pets, too.

    I have had my 11 year old Rottweiler on Cartrophen Injections for the last three years with no negative side effects. He has Grade I DJD in his Elbows and had quite a bit of Pain. He goes for his Monthly injection as Maintenance and usually just before the Winter (like now) I give him a 1xweekly series of 4 shots to help him throught the Winter. The Cold and Damp Weather is brutal for him. All other Anti Inflammatoires I have tried upset his Stomach to the point of projectile Diarrhea.

    MOST IMPORTANT:

    If anyone has any knowledge of how to ameliorate the effects listed in these 64 or so posts due to cartrophen injections, please share – forthwith.

    My Grey-baby will be 16years old in December this year. Granted, he has been undergoing treatment for high blood pressure (amlodipine), liver, kidney, and gastrointestinal diseases/disorders for several years. We know there are masses in his GI tract, but they seemed mostly benign, and if there were cancerous cells, he was not presenting with serious symptoms, and the distribution and placement of the masses made surgical removal not feasible. He carried on 1.5 to 2 years in this way without succumbing to anything like what he has now.

    Greystoke has finally become an old man these past few months, being rather sedate, no playing, etcetera, lots of cat napping, but he had mobility; he could jump up and down 2.5 to 3 feet, drink, eat, enjoy petting, etcetera. Granted, my little man had lost weight; granted, he was in a weakened state; granted, he receives subcutaneous fluid injections about 3 times per week, but my little man received one Cartrophen injection Sunday afternoon, October 13, 2013. It is now Wednesday, October 16, 2013, and I have to feed and water my boy with syringes; he cannot walk a straight line – he staggers and lilts, but not too far – he only has a few steps in him before he lies down where he stands, er, lilts. He is clearly uncomfortable; doesn’t want to be touched; won’t eat or drink, even though he is hungry and thirsty (he is licking his chops and sometimes leans toward the food, even lapped at it a couple of times tonight, but cannot bring himself to chew/swallow). He smells toxic. It was Sunday or Monday when we realized there was moisture on the human bed under his cat bed he was sleeping in; apparently, he urinated – significantly, either in his sleep, or just curled up and went to sleep in his urine-soaked bed – NOT normal behaviour for my cat. He has been incontinent since; he hasn’t eaten enough to produce a bowel movement. He moves a few steps a day; we bring him what he needs.

    Obviously, I am now considering “options”. I asked for a painkiller because we’ve known he has some tenderness in his back end for some time (as in tenderness, and ability to walk … and jump). I asked for cortisone, was told that was a terrible idea, but Cartrophen was what he needed. Yeah, I’m sure that cortisone would have been just *terrible*. No option for pain was offered other than Cartrophen, and I asked more than once, more than one vet. I have seen on the internet other people posting all kinds of drugs they can give their cats (maybe this is a USA vs. Canada thing). No one mentioned anything about not giving to cats with liver or cancer issues – you’d think my vets of 10 years would know that they were treating my cat for liver, kidney, gastrointestinal disorders, with a smattering of masses along his gut.

    I am not impressed – and not for the first, or even second time.

    What is obvious to me is that if a patient has a weakness already, perhaps undiagnosed or stagnant, doses of Cartrophen exacerbate or flare the disease/issue and make it scream out every associated symptom. Whether or not it causes cancer may be debatable, but if you have a patient that is technically diseased but still maintaining a degree of health, this “treatment” will probably kill the patient in short order.

    I have been reading these comments and I now feel very concerned about my dog! I have a 3 year old border collie and last week he had been running in the garden and had obviously slipped and twisted himself as he couldn’t get up, he was not able to put any weight on his back leg and it was very distressing to see. My husband took him straight to our vets he told him our dog may have done damage to his back and gave him an injection. My husband came home and I asked what the injection was called and he said cartrophen and that he needed to go back the following day for another one. I googled this and saw it was a drug that helped arthritis. Our dog the following day was so much better and since he has been back to normal wanting to run but obviously I have to keep him on a lead for a while. The reason I found this blog is because my dog has not had a solid poo since and I decided to google side effects. I am now very very concerned after reading other peoples experiences and now think my dog is only 3 years old and has had 2 of these injections!!!

      I researched everything on the Net before giving this drug to my 12 1/2 years old pure Boxer. I was so scared about all the negative comments. Before this drug, I have tried rimadyl combine with pain killer and still he was in pain. Anyway, I don’t work for the pharmaceutical company, I just want to say that Boogie has been on Cartrophen for 8 months now and he is jumping like he is a puppy again and anyone who know Boxer know what I am talking about. Yes, maybe this drug is not for every dog but for me, it has been a savier. My old boxer is running again. As I am writing this, he is close to 13 years old for which I understand is very old for a Boxer. Lifespan is more like 10-12 max. So far everything is ok. Anyway, here is my email if you want to talk about it. marc-rrt@hotmail.com. Again, I don’t work for any pharmaceutical, just wanted to give my own experience. Feel free to contact

        My 16 y.o. staffy was great on Cartrophen for about 12 months, then had a reaction within an hour of injection. Couldn’t walk properly, fell over, legs not strong enough to hold him up. The vet said not possible to be a reaction andgave him pain releif. The next C due I asked about the last reaction to hear that it was not possible to be the C. Worse reaction this time, he bumped into walls, was totally disoriented and very stressed. Lay in the garden crying, couldn’t sit still and couldn’t walk within tripping and falling. Thsi time the vet said all the info she had read (from the pharmaceutical co) indicated no side effects. I told her about this blog, she gave pain relief again. Sam is better but has lost some strength and stamina in the 3 weeks since. I have just received a bill for the after hours treatment for more than $250 … I’m about to discuss that. I will never subject my baby to Cartrophen again, can’t believe the vets are so stubborn about it’s side effects… wish me luck!

        Vets are reluctant to acknowledge that there might be a connection. My 12 year old yellow lab had great difficulty walking after the injection and then died within a week.

    Our British Short Hair, male, developed Hip Dysplasia at age 2 years. He is now nearly 5 years old and has a Cartrophen injection every 4 weeks. He also has a Onsior tablet and Glucosamine tablet daily. The cost doesn’t worry me as he is insured for life. However on ready these excellent articles I wonder are we doing him more harm than good letting our Vet do his own thing?
