Arthritis in Dogs
Pictured is my dog Piglet at age 15. Piglet had severe degenerative joint disease in both elbows. See the link to Piglet's Story below for how I managed her condition and kept her mobile for 17 years.

Disclaimer: I am not a veterinarian, nor do I have any formal training in any medical field. The information presented here is not meant to replace your vet's advice or prescribed medications, but only to suggest additional options to explore, based on your dog's condition.
The number of things you can try to help your dog with arthritis can seem overwhelming, so I'm going to suggest some ways to get started.
1. WEIGHT & DIET One of the best things you can do for a dog with arthritis is to keep him lean. Ideally, your dog should be quite lean, with ribs easily felt but not hip or backbones protruding. If your dog is at all overweight, start him on a weight loss program right away -- note that traditional high-carbohydrate weight loss products are not recommended. See my article on Weight Loss Diets for some guidelines on helping your dog to lose weight. Also see the section below on Supplements and Diet Guidelines for dogs with arthritis for more information, and the section on Senior and overweight dogs on my Commercial Dog Foods page.
If possible, reduce the amount of grains and starchy carbohydrates in the diet and increase the amount of protein. This can be done by feeding a better quality food, by using canned instead of dry foods, by adding fresh foods such as eggs and meat to the diet, or by feeding a home made diet. Many arthritic dogs improve when grains are removed from the diet, but if this doesn't help your dog, you don't need to continue to avoid them.
Moderate exercise can also be good for dogs with arthritis, and can help with weight loss. See Exercise and the Treatment of Arthritis for more information.
2. GLUCOSAMINE I think all dogs with arthritis or known joint problems should be on some sort of glucosamine-type therapy. This should include oral supplements that contain glucosamine (sulfate or hcl), chondroitin sulfate, green lipped mussel (perna canaliculus), hyaluronic acid, or a combination of these. It may also include the injectable form, Adequan or Cartrophen. Since these supplements are the only things that actually help protect the joints rather than just treating the symptoms, they are a must for all dogs with joint problems. Different dogs respond differently to different supplements, so find one that works for your dog rather than relying on what has worked for others, though that may be a good place to start. Give high doses at first, so you will be able to tell if it is working. If you get results, you can try reducing the dosage to see if your dog will do well on less. If you don't get results, try a different brand. See Glucosamine and other GAGs for more information.
3. FISH OIL If I were to suggest any single nutritional supplement for dogs with arthritis, it would be fish oil (fish body oil, such as Salmon Oil or EPA oil, not cod liver oil). Fish oil provides omega-3 fatty acids that help reduce inflammation. They are beneficial no matter what type of diet you feed. Note that omega-3 fatty acids are fragile and break down quickly when exposed to light, heat or air, so just feeding a food that has omega-3 fatty acids added may not be helpful. Give as much as 1000 mg fish oil (300 mg EPA/DHA) per 10 lbs of body weight daily. Because fish oil depletes vitamin E in the body, you should also give vitamin E supplements whenever you supplement with oils of any kind. Give around 50 IUs to a small dog, 100 IUs to a medium sized dog, up to 200 IUs for a large dog, anywhere from daily to once or twice a week. See Fish Oil (Omega-3 Fatty Acids): a Proven Treatment for Canine Arthritis for information on two studies published in the JAVMA in 2010 showing how dogs with arthritis improve when given fish oil supplements.
4. PAIN RELIEF If your dog is in pain, look for ways to relieve it naturally before turning to NSAIDs. DLPA is the first thing I would try, it made a definite difference for my dog and is very safe to use. For worse pain, consider using Tramadol, a synthetic narcotic that can also be used in conjunction with NSAIDs. I would also be trying a variety of natural anti-inflammatories, to see if any of them seem to make a difference. I'm always trying something new with my Piglet. If one supplement doesn't seem to help, I simply move on to another one when I run out. Anything that does seem to help I continue using. See the section on Chronic Pain Relief for more information on drugs used to help dogs with arthritis pain.
5. ALTERNATIVE THERAPIES Many people have reported success using acupuncture for arthritis. Unfortunately, I am not one of them, and at least in my area, acupuncture is very expensive (over $100 per visit), so it's not the first thing I would recommend trying unless you have access to it at a more reasonable rate. If your dog does respond to acupuncture, you can also consider gold bead implants, which are a form of permanent acupuncture. Chiropractic can also be helpful in many cases, although again, I have not had success with it myself. I do not recommend VOM (veterinary orthopedic manipulation), a form of chiropractic that makes unrealistic claims and in our case had no benefit at all, but other forms may be very helpful for many dogs. I am not a believer in homeopathy, but some people have reported success using homeopathic remedies for arthritis pain, including Zeel and Traumeel.
My dog Piglet (whose picture appears at the top of this page) had surgery for elbow dysplasia on both elbows before her second birthday, followed by surgery for a ruptured cruciate at age 3. She was on daily Rimadyl/Etogesic with occasional doses of prednisone up until age 7. At that time, I switched her to a raw, grain-free diet with natural supplements. She improved so much that I was able to discontinue all medications. At age 10, she ruptured her other cruciate and again had surgery (April, 2002). It took about three months for us to build back up to her usual 2 mile daily walks, but she did extremely well, became just as active as ever, and was still on no medications for her arthritis, despite the fact that x-rays confirmed severe degenerative joint disease in both elbows. At age 11, she became lamer in one elbow, and after many months of struggling to get her back to where she had been before, I put her back on NSAIDs (Metacam). She continued to be slower than before and I had to cut back on walks because she couldn't go as far. After about a year, she improved again, and while still slower than she used to be, could go on full length walks again at age 13. Then I discovered a very small tumor in her foot, between her toes. It was removed immediately, and when she recovered, she began taking very long walks, longer than ever before. Now, at age 14, she walks 1 1/2 to 2 hours at a time, going sometimes 3-4 miles, almost every day. I suspect that the tumor had been bothering her to walk on. It never hurts to keep looking for other possible causes of lameness, even when you know your dog has bad joints.
Here is what I have done with her:
- First, I feed a raw, grain-free diet. I also weigh all her food using a small postage scale, originally to gradually reduce her weight and now to maintain it (she weighs about 33 pounds and is lean but not skinny; she weighed 36 pounds at the age of 10 months and has been as high as 42 pounds). Keeping dogs with arthritis lean is one of the best things you can do to help them. Also, grains tend to increase inflammation and aggravate arthritis. Many dogs improve when grains are removed from the diet (most dry foods are high in grains, though there are a number of grain-free foods being offered, see my Dry Dog Foods web page for more info; note that there are also some canned foods that are grain free).
- I give fish oil(body oil, not liver oil), Vitamin E(which should always be given when supplementing oils), and antioxidants, usually Cell Revive 880 (same as Cell Advance 880) or sometimes Thorne Veterinary Immugen. I also give a Vitamin B-50 complex daily -- note that niacinamide (a form of vitamin B3) has antioxidant and anti-inflammatory properties, and may help to rebuild cartilage. According to a vet who recommended it to me, the dosage for Piglet's size (35 lbs) is 50 mg, which is what I get in the B-50 vitamin complex that I use. See Nutrition Q & A (scroll down to the last question) for more information on niacinamide.
- It is important that dogs with arthritis get adequate, but not excessive amounts of calcium, vitamin D and magnesium. If you are feeding a commercial diet, there should be no need to supplement with any of these. If you are feeding a home made diet, it might be helpful to supplement with small amounts of vitamin D (such as from cod liver oil) and magnesium. If your diet includes raw meaty bones, they should not account for more than around 50% of the diet. If your diet does not include bones, then you need to add calcium at the rate of around 1000 mg per pound of food (1/2 teaspoon of ground eggshell yields about 1000 mg of calcium). Piglet gets raw meaty bones as about half of her diet, and I have not been supplementing with magnesium or vitamin D.
- I have rotated among Yucca Intensive, Bromelain, Quercetin, Boswellia, Turmeric (or its extract, Curcumin), Sam-E, Borage Oil and other natural anti-inflammatory herbs and Nutraceuticals. It is difficult for me to tell how much any of these have helped, but I believe all have had some benefit. Note that Bromelain is most effective when given away from meals for an anti-inflammatory effect (otherwise, it is used for digestion), and may work best when combined with Quercetin. See Natural Anti-inflammatories for more information.
- Piglet has been on a glucosamine/chondroitin supplement for most of her life. I believe this is one of the most important things you can do, as these substance don't just treat the symptoms, they can actually help rebuild cartilage and restore synovial (joint) fluid. I currently use Arthroplex, which includes bromelain, boswellia, Green Mussel (Perna Canaliculus, which is a source of chondroitin) and DLPA for chronic pain. I give these supplements away from meals, which may make them more effective.
- Piglet also gets fresh crushed raw garlic (one small clove per day, as too much can be toxic), alfalfa, organic (raw) apple cider vinegar (about half a tablespoon daily) and fresh raw ginger in her food, all of which may help with arthritis.
- Before starting Piglet on Metacam, we used Willow Bark instead of Aspirin for occasional pain relief when she overdoes it, as it is easier on the stomach. You can also use buffered aspirin, such as Ascriptin or Vetrin (which comes in smaller doses). Giving with food may help prevent stomach upset, but not ulceration. Do not combine Aspirin with Willow Bark or any NSAID, such as Rimadyl or Etogesic. Also, do not use enteric coated aspirin, which can be dangerous for dogs. See Chronic Pain for more info on aspirin and other NSAIDs.
- Piglet got something called DogLeggs for Christmas. They keep her elbows warm and padded at all times. They appear to be comfortable, she wears them all of the time except when we go on our walks and during the day when it is hot, and she seems to enjoy them.
- In June, 2003, I started Piglet on a supplement called Arthroplex, and have been very happy with the results. For a couple of months, she had been favoring her left elbow -- it's usually her right that gives her the most trouble, so having to favor the left made her fairly lame. I chose Arthroplex because of the DLPA, but it also includes glucosamine, green-lipped mussel, bromelain and boswellia, so I discontinued the Flexile Plus and Green Mussel and instead gave her two capsules Arthroplex twice a day (maximum dosage for her size). Within four days, she was no longer lagging on our walks, and within a week, there was no longer a noticeable limp. She also still gets Yucca Intensive and fish oil, but no other supplements for arthritis currently. Unfortunately, after about a month of doing well, Piglet got worse again. We have continued the same regimen of supplements, including the DLPA.
- In June, 2004, I tried switching from Arthroplex to SynoviG3, which several people had reported good success with. Unfortunately, it did not work for us and Piglet immediately got worse, even when I started adding DLPA back in separately. We have since returned to the Arthroplex, and also Yucca Intensive, which I had discontinued after starting Metacam. In fact, I am not sure how much the Metacam is helping, and have discontinued it for now, she seems to do as well on Arthroplex and Yucca Intensive as she did with Arthroplex and Metacam.
- In October, 2004, she went back on Metacam, which really does seem to help Piglet's mobility. She's still not very fast, but she's going on much longer walks now than she was when things were bad. She continues on Arthroplex, and I switched from Yucca Intensive to an herbal blend that has yucca, alfalfa and some other ingredients (Animals' Apawthecary Alfalfa/Yucca Blend), so that may also be part of why she's doing better. I've been having very good luck recently using herbal blends in tincture form for dogs, including products from Animals' Apawthecary (Alfalfa/Yucca Blend and Senior Blend), Tasha's and Azmira. Piglet will be 13 in December.
- In September, 2005, I found a small tumor between her toes and had it removed. When she recovered from surgery, she began taking very long walks, going 1 1/2 to 2 hours at a time, often as far as 3-4 miles. As of January, 2006, at age 14, she is walking further and longer than ever before. She is not fast, but keeps a good walking pace and does not slow down toward the end. She continues on Metacam, though I take her off it periodically and she still does pretty well, but I figure she needs all the help she can get, and since she tolerates it very well (no digestive upset at all), I keep her on it most of the time. She remains on Arthroplex and is also currently getting curcumin.
- It's December, 2006, and Piglet has just turned 15. She continues to take me on 1 to 2 hour walks every day. I let her set the pace and decide how far we go, so as not to push her, though I occasionally have to ask her to turn back when we've gone a very long way and she wants to keep going. She currently takes Arthroplex (source of glucosamine, green-lipped mussel, DLPA, boswellia, bromelain and vitamin C), high dose fish oil, turmeric, SAM-e, vitamin E, as well as alternating between the herbal Senior Blend and Alfalfa/Yucca blend (both from Animal’s Apawthecary). In addition, she takes Metacam, and I give her one dose of Tramadol in the morning to help with walks. She is also on sertraline (Zoloft) for anxiety, which may help with pain as well.
- Piglet turned 16 in December, 2007. She slowed down quite a bit early in the year, taking shorter walks at a slower pace. We tried shock wave therapy in August and September, which has helped a little, letting her take longer walks (usually 45 minutes to an hour, with occasional longer walks up to 2 hours, which she had not done for six months prior to the therapy), and sometimes at a trot rather than her usual walk. She remains quite healthy. She currently takes Arthroplex (source of glucosamine, green-lipped mussel, DLPA, boswellia, bromelain and vitamin C), fish oil, turmeric, SAM-e, vitamin E, as well as alternating between the herbal Senior Blend and Alfalfa/Yucca blend (both from Animal’s Apawthecary). In addition, she takes Metacam, and I give her one dose of Tramadol in the morning to help with walks (I would give more but have to be cautious about combining it with Zoloft, which she gets for her generalized anxiety disorder). I also began giving her amantadine a couple of months ago, which is supposed to enhance the effects of other pain medications; I'm not sure if it's made any difference or not. I was able to get it in liquid form thru Costco (needed in order to get the correct dosage, as the pills are too high). Zoloft (sertraline) may help with pain as well. I should also note that I have gradually decreased the amount she is fed and the amount of fat in her diet as her exercise level has decreased to help her maintain her body weight at 34 lbs.
- July, 2008: Piglet is now 16 1/2, an amazing age for a Shar-Pei. She remains quite healthy and still enjoys her walks, but continues to be very slow. I've decided to try Pulsed Signal Therapy (PST) in the hopes that it will help her be able to go further. I stopped giving Piglet Arthroplex, as she has high blood pressure and the DLPA it contains can make that worse -- her kidneys and heart are fine, but she has some corneal degeneration and pigmentary keratitis that interfere with her vision, and I was afraid that she might blow out her retina due to the high blood pressure (she's also now on blood pressure medication). I first tried Dasuquin as a replacement, but she seemed a little worse on that, so I switched to Sea Mussel Plus and I've been happy with that. I also added three anti-inflammatory supplements in the hopes it might make enough difference that she would not need PST, but no such luck -- she may be a little better, but not a lot. The new supplements I added were Microlactin, Boswellia, and a combination Bromelain and Quercetin (I get all of these, including Sea Mussel Plus, at vitacost.com). That's in addition to her usual supplements of fish oil, turmeric (curcumin), SAM-e,CoQ10 and a multi-vitamin, and her usual medications, Metacam and Tramadol. Piglet starts PST next week, going every day for 9 consecutive days. I will update this site if I notice any improvement.
- October, 2008: Piglet has continued to be quite lame. The pulsed signal therapy (PST) did not help her at all. I tried switching her from Metacam to Previcox, which seemed to help but upset her stomach. I then tried prednisone, which helped a lot, but not being sure it was necessary, I tried another new NSAID, Zubrin. This one she tolerated well, but she returned to being quite lame. I've since switched her back to prednisone, which she is likely to remain on for the rest of her life. At almost 17, I don't have major concerns about its long term effects. Her dosage is every other day, which is also supposed to decrease side effects. Note that I kept her off all drugs for 72 hours in between each change in medication, as it's dangerous to switch from one NSAID to another, or to pred, too quickly.
- January, 2009: Piglet is now 17. She is doing well on the prednisone; although still favoring her right elbow, she is able to take long walks again, averaging around an hour a day, though she is very slow. I have discontinued all her other supplements, as it's unlikely that any natural anti-inflammatories would add anything over and above what prednisone provides, and she's developed some digestive problems that seem to do better when she's not getting supplements.
- March, 2009: Piglet is gone. She went downhill sharply in the last few weeks of her life, developing dementia and unable to cope with her limited vision. She was still mobile to the end, though very slow. She had a wonderful life, far longer than I ever dreamed when she was diagnosed with elbow dysplasia at a year old. Her condition helped me find the path to a natural diet and supplements, and to learning more about dog health and nutrition. She will always be in my heart.
There are email lists called OrthoDogs and CanineHD at Yahoo Groups that offer additional information about surgery for joint problems. Also see AbleDogs and Dodgerslist for dogs with back problems. There is a list called TPO that talks about surgical options for hip dysplasia and cruciate ligament repairs (also see the site at http://www.lauriebryce.com/tplo/ for a great deal of information and links about orthopedic surgery).
Note I am not advocating TPLO surgery for cruciate ligament injuries (and that is not what I had done on Piglet) -- it works well for some dogs, but I've heard of others where the joint doesn't heal properly and the dog is worse off than before. The skill of the surgeon may be a factor. Strict activity restriction is required, and failure to do so may contribute to complications. I have also heard reports, both directly and indirectly, of dogs developing bone cancer following this surgery, as well as other long-term complications. Removal of all implants six months to a year following the surgery may help to reduce this risk. I would seriously consider TPLO surgery for large, active dogs, but probably not for smaller or less active dogs, for whom conventional surgery seems to work well. See TPLO Awareness for more information. Also see Tibial Plateau Leveling Osteotomy - TPLO for a good overview. There are other forms of leveling osteotomies available as well, such as TTA (tibial tuberosity advancement). See TPLO vs. TTA for Cranial Cruciate Ligament Repair for more information.
MSU has recently begun offering arthroscopic cruciate ligament (knee) surgery for dogs. This is combined with traditional cruciate repair, involving sutures to stabilize the knee.
There is a new cruciate surgical procedure developed in 2006 at the University of Missouri, called TightRope, named after the rope-like material used to link the two bones in the knee joint. While the material used is new, the procedure is similar to traditional extracapsular cruciate repair surgery, not like TPLO or TTA, which cut the bones. TightRope is considered an easier procedure than TPLO or TTA, especially for a general practitioner (as opposed to a surgical specialist). While the TightRope procedure is relatively new, the results look quite promising. It is more costly than traditional repair, but less expensive than TPLO and similar leveling osteotomy procedures. See the following for more information:
- MU veterinarian develops 'TightRope' surgical technique
- Walking the TightRope on cruciate repairs
- Tightrope CCL for treating canine cranial cruciate deficiency
- TIGHTROPE CCL FOR TREATMENT OF CRANIAL CRUCIATE DEFICIENCY IN DOGS: Technique and results of a prospective comparison to TPLO using a validated outcome measures
One Pro’s Take on Orthopedic Advances (quotation from a surgical specialist in November 2012): "When I came to OSU 19 years ago, TPLO surgery for cruciate disease was just starting to be talked about. Cruciate repair was mostly done by lateral suture, essentially mimicking the action of the anterior cruciate ligament,” Rochat recalled. “Cruciate repair surgery is now largely TPLOs. Another procedure, tibial tuberosity advancement, is a new alternative that is purported to be easier to do, with fewer complications, yet the evolving literature doesn’t totally support that.
“Nevertheless, while the general subjective experience is that TPLO works very well, what little objective science there is still leaves us questioning that,” Rochat continued. “Properly done, a lateral suture stabilization technique [the older style of cruciate surgery] can yield good results. Again, the quest for accurate, unbiased evidence for the best solution for cranial cruciate ligament disease continues."
If your dog has orthopedic surgery, there are a couple of things you should be aware of that your vet may not be current on. The first is pain management, see my my section on Pre- and Post-Op Care for more information (I also have links at the bottom of that section to braces, slings and carts). Also ask about using intra-articular injections of either bupivacaine or morphine during surgery, which has been shown to provide more pain relief in the first 24 hours after surgery (see Postoperative analgesia for stifle surgery: a comparison of intra-articular bupivacaine, morphine, or saline).
The second is that recent research shows that it is important to start doing physical rehabilitation right away, at least in the case of knee surgery, rather than waiting six weeks. Contact me privately if you want a copy of the rehab instructions the surgeon gave me when Piglet had her second knee surgery in 2002. See The American Association of Rehabilitation Veterinarians to locate a rehab specialist in your area. Also see Physical Therapy for Pets for an overview of how important this type of therapy can be following an injury.
Conservative management may be tried in place of surgery if your dog has a cruciate ligament (knee) injury. If no improvement is seen within six to eight weeks, you should then move on to surgery. It is imperative that activity be limited during this time. It is my opinion that a ruptured cruciate will do better with surgery than without, but if there is any doubt about the diagnosis (which cannot be done via x-ray alone), then it may make sense to wait. As long as activity is restricted, no harm should come from waiting for up to two months. See Treating Canine Ligament Injury Without Surgery for more information. Also see How to Confirm Partial ACL Tear for some technical information on how vets try to confirm ACL injuries and differentiate between hip and knee pain. There is a Yahoo Conservative Management group for discussing this option with others. Consider a stifle (knee) brace, such as those from OrthoPets, to help protect the knee and prevent reinjury during the recovery period (see Braces, Splints, Orthotics and Prosthetics for more options).
Changing Views On CCL Repair, written by a well-known vet who practices "Integrative Pain Medicine and Natural Healing," talks about the use of Prolotherapy for treating cruciate ligament laxity (looseness), but I don't know whether it would help with a torn ligament, and it's hard to find a vet who does it. Also see Questioning Canine Cruciate Ligament Surgery, by the same author, which presents a hodgepodge of arguments against surgery, though the information is scattered and appears to apply primarily to TPLO, not other forms of cruciate ligament repair. For example, she says, "about half of Labradors rupture the contralateral CCL [cruciate ligament in the opposite leg] within six months after tibial plateau leveling osteotomy [TPLO]," but she does not compare this to rates of injury for other forms of therapy, which makes the statistic meaningless, at least in terms of trying to decide between treatment modalities. The same author collaborated with others on a third article, Treatment Options for Canine Cruciate Disease, which supports surgery in most cases, particularly for dogs over 15 kg (33 pounds), but also suggests laser therapy, acupuncture, and other modes of physical rehabilitation either after surgery, or in place of surgery if surgery cannot be done (see Other Therapies for more information on these modalities).
See Other Therapies above for more information on rehabilitation following injury or surgery. Also see Post Surgical Aids for information on a variety of devices that may be helpful, including e-collar alternatives, slings, braces, support harnesses, and more.
The University of Tennessee is studying "The effect of diet on muscle atrophy following surgery for cranial cruciate ligament rupture." The study is ongoing as of September, 2009.
The University of Florida performed its first total knee replacement surgery in a dog in 2012. They are seeking additional dogs with severe osteoarthritis in the knee for a clinical study on total knee replacements for dogs. See First canine total knee replacement at University of Florida a success for more information.
