The most common chronic condition in senior dogs — and one of the most manageable.
Understanding the condition
Osteoarthritis affects roughly one in five adult dogs, and most dogs over eight show some degree of joint change. It is progressive — cartilage does not regrow — but the pain and mobility loss are very treatable when managed early and consistently.
Effective arthritis care is multimodal: weight management, controlled exercise, veterinary pain medication where prescribed, and evidence-supported joint supplements. No single piece replaces the others, and supplement choices matter most when your dog is also on prescription medication — several joint supplements interact with NSAIDs.
Signs to watch for
- Stiffness after rest that improves with movement ("warming out of it")
- Reluctance on stairs, jumping into the car, or getting on furniture
- Lagging on walks or sitting down mid-walk
- Licking or chewing at a specific joint
- Irritability when touched near hips, knees, or elbows
- Muscle loss over the hindquarters
Managing it well
Weight first
Every extra kilogram multiplies joint load. In overweight arthritic dogs, weight loss alone measurably improves lameness — it is the highest-value intervention available.
Motion is lotion
Regular, low-impact exercise (leash walks, swimming) maintains muscle that stabilizes joints. Avoid weekend-warrior patterns — consistency beats intensity.
Veterinary pain control
Prescription NSAIDs (carprofen, meloxicam, grapiprant) are the backbone of moderate-to-severe arthritis care. Supplements complement them; they do not replace them.
Evidence-graded supplements
Omega-3s (fish oil, green-lipped mussel) have the strongest evidence for reducing inflammation. Glucosamine/chondroitin has moderate, mixed evidence. Always check interactions with your dog’s medications first — several joint supplements add to the antiplatelet effect of NSAIDs.
Track what changes
Arthritis progresses slowly, which makes memory unreliable. Weekly mobility and pain scores reveal whether a change in the plan is actually working.
When to call the vet: Sudden non-weight-bearing lameness, a hot swollen joint, or pain that stops your dog eating are not arthritis-as-usual — see your veterinarian promptly.
