How common is it
Canine osteoarthritis is far more common than most owners realize. By age 7, roughly 20% of dogs have clinically detectable arthritis. By age 12, the number is well over half. Large-breed dogs and dogs with hip or elbow dysplasia show signs even earlier, sometimes before age 4.
Despite the prevalence, arthritis is consistently underdiagnosed. Dogs hide pain, owners attribute slowdown to age, and unless something dramatic happens (sudden limp, refusing to walk), early arthritis often goes years without intervention.
The home checklist
Score your dog on each of the following over the last two weeks. Honest answers, not what you hope is true.
Movement: - Slower to get up from lying down - Stiff for the first few minutes of a walk, then warms up - Reluctant to jump on the couch, into the car, or up the stairs - Limps after rest, especially in the morning - Walks shorter distances than they used to
Posture and resting: - Lies down with legs awkwardly positioned - Switches sleeping position more often during the night - Sits crookedly with one leg cocked out - Avoids hard surfaces, prefers extra padding
Behavior: - Licks a joint, often the wrist, knee, or hip - More irritable, especially when touched in certain spots - Less interest in play - Hesitates more before any movement requiring effort
If you check three or more, the probability of clinically meaningful joint disease is high. If you check six or more, schedule a vet visit.
Arthritis symptom checklist, by stage
| Stage | Common signs | Action |
|---|---|---|
| Pre-clinical | Slight slowing on walks, occasional stiffness | Joint supplement, weight management |
| Early | Stiffness after rest, reluctance to jump | Supplement + vet baseline exam |
| Moderate | Persistent limp after activity, avoiding stairs | Supplement + likely NSAID trial + vet follow-up |
| Advanced | Frequent or constant limp, muscle wasting, behavioral changes | Full vet workup, multi-modal pain management |
What the vet exam adds
A good orthopedic exam is the next step. Vets assess range of motion, look for swelling or pain on palpation, and watch the dog walk and stand. Many cases of clinical arthritis are confirmed at this stage without radiographs.
When radiographs are needed, they show joint space narrowing, bone spurs, and other structural changes. Severity on radiographs does not always match severity of symptoms; some dogs with mild changes are very painful, and some dogs with significant changes function well.
What a vet visit really gives you is staging and a treatment plan: weight management goals, appropriate exercise (yes to swimming and leash walks, no to ball-chasing on slick floors), supplement recommendations, and the threshold at which prescription pain management makes sense.
What to do if the answer is probably yes
Five things to do today:
1. Weight check. Every extra pound multiplies through the joints. If your dog is over their ideal weight, a 10% reduction can change everything.
2. Soft, supportive bedding. Hard surfaces aggravate arthritic joints. Memory foam or orthopedic beds make a clear difference.
3. Slow, regular exercise. Daily leash walks, swimming if available. Avoid weekend-warrior bursts of activity.
4. Start a quality joint supplement. Glucosamine + chondroitin + MSM + green-lipped mussel + turmeric is the multi-ingredient approach with the strongest evidence.
5. Vet exam. Get a baseline, including mobility scoring and (if appropriate) radiographs. Knowing where you are starting helps you measure progress.
