Arthritis Treatment: What Works, From Weight to Medication
What the evidence says about treating arthritis in dogs: weight, exercise, rehabilitation, supplements and medicines, and the myths to drop.

“Musculoskeletal pain (e.g., OA) is the most common form of chronic pain in dogs”, according to the American Animal Hospital Association’s 2022 pain guidelines (AAHA, Chronic Pain Assessment in Dogs). OA is osteoarthritis, the wear and inflammation of joints that most people mean by “arthritis”.
While no single treatment fixes it, several things help, and they work best together. AAHA’s senior care guidelines put it plainly: treatment “must be integrative and multimodal”, and “Addressing these issues early in the course of the disease improves outcome” (AAHA, 2023 Senior Care Guidelines: Pain Management).
This page sets out what the guidelines say about each option. It doesn’t replace an examination. Your vet needs to confirm it’s arthritis and not something else first.
1. Weight
This is the treatment owners control most. AAHA writes that “Longitudinal cohort studies in the veterinary literature strongly support maintenance of a lean body condition score” for “decreasing the rate of OA progression and extending life span” (AAHA, Nonpharmacologic Modalities).
Fat tissue isn’t just extra load on the joints. AAHA explains that it “secretes a mixture of cytokines”, signalling molecules that contribute to inflammation and pain.
Ask your vet to score your dog’s body condition and, if needed, to plan safe weight loss.
2. Exercise and rehabilitation
Movement helps. AAHA notes that “daily walking has been associated with a decrease in the severity of lameness in dogs with hip dysplasia”, though it says controlled trials in dogs are “sparse”.
Rehabilitation therapy is the veterinary version of physiotherapy. It can include stretching, massage, joint mobilisation, targeted exercises and hydrotherapy. AAHA’s advisory panel “believes that rehabilitation therapy should be considered part of a comprehensive wellness plan”, while admitting “a dearth of controlled prospective clinical trials”.
3. Changes at home
Small changes can make a big difference to a stiff dog. AAHA’s guidelines suggest secure footing such as carpet runners, and ramps or steps to reach favourite spots. The senior guidelines add rugs or yoga mats, raised food and water bowls, supportive harnesses and suitable beds.
4. Supplements
Most joint supplements have weak evidence. AAHA cites a review that “concluded that the strength of evidence was low for all nutraceuticals except for omega- 3 fatty acid in dogs.”
A 2022 meta-analysis reached a similar view: omega-3 diets and supplements showed clear pain relief, while glucosamine and chondroitin did not (Barbeau-Grégoire et al., Int J Mol Sci 2022). → Glucosamine and Chondroitin: The Meta-Analysis Says No
Ask your vet before adding any supplement. AAHA’s senior guidelines warn that some can interact with medicines older dogs often take.
5. Medicines
Your vet will choose a medicine for your dog. This page doesn’t recommend one or give doses. What AAHA’s guidelines say about the main groups:
| Medicine group | What AAHA says |
|---|---|
| Anti-inflammatories (NSAIDs) made for dogs | Several are approved for chronic pain. Side effects can occur, but “the true incidence is likely low (and unknown).” |
| Anti-NGF antibodies (monthly injection) | “good pain relief” in studies. Newer safety reports are covered in our separate article. |
| Oral opioids, long-term | “not recommended for chronic pain control.” |
| Gabapentin | Widely used, but “It has not been evaluated for analgesic efficacy in chronic pain in dogs.” |
| Cannabinoids | “the data required for evidence-guided prescriptions of cannabinoid compounds in veterinary medicine are lacking.” |
| Joint injections | “emerging evidence”, though “most studies are small and results have been mixed.” |

Our note: AAHA singles out one nerve-pain medicine, which this page names. Ask your vet whether it suits your dog.
Our note: Which arthritis medicines are approved for dogs differs by country, and CBD’s legal status varies.
6. Acupuncture
AAHA reports that acupuncture “was not found to be beneficial for the treatment of pain associated with OA in dogs”, though it may help some other kinds of pain.
7. Tracking whether it’s working
AAHA suggests owners take videos of their dog moving at home, which help vets “monitor responses to medications and therapies.” Vets also use owner questionnaires that ask the same questions over time. AAHA names the most widely used: the Canine Brief Pain Inventory and the Liverpool Osteoarthritis in Dogs questionnaire.
X-rays don’t tell the whole story. AAHA notes that “Joint pain on palpation and radiographic signs of OA often correlate poorly.”
Our note: AAHA mentions free owner questionnaires. We haven’t checked where they are published or their terms of use.
8. Who funds the guidelines
AAHA’s 2022 pain guidelines “are supported by generous educational grants from Arthrex Vet Systems, Boehringer Ingelheim Animal Health USA Inc., Elanco, and Zoetis.” These companies make products used for pain in dogs. That doesn’t make the guidelines wrong, but you should know.
9. What we could not verify
| Commonly said | What we found |
|---|---|
| “Arthritis is just part of getting old” | It’s treatable, and AAHA says early treatment improves outcome. |
| “Rest is best for arthritic dogs” | Not what AAHA says. It supports exercise and rehabilitation. |
| “Long-term anti-inflammatories always damage organs” | Not shown in long-term studies, AAHA says; side effects can still happen. |
| “An X-ray shows how much pain a dog is in” | No. X-ray findings and pain often don’t match. |
