Early Signs of Arthritis in Dogs (Including the Subtle Ones Most People Miss)

By the time a dog is visibly limping, arthritis has usually been progressing for years. Most owners only spot it once it's advanced — but earlier signs are there months before. Here's what to look for, and when to act.

Why early detection matters

Arthritis is progressive and irreversible. Once cartilage is lost, it doesn't grow back. But the rate of loss can be slowed significantly with the right intervention. Catching it at year one of disease progression rather than year three or four makes a huge difference in your dog's quality of life over their lifetime.

The subtle early signs

1. Slower to rise — even briefly

The most common early sign. A dog who used to spring up when you grabbed the lead now hesitates for a beat. Or takes 2 seconds to stand from lying. Often dismissed as "old age" — but old age and arthritis are not the same thing.

2. Sitting "off-centre"

Dogs in early hip discomfort often sit with one leg tucked under and the other splayed to the side. Or they roll onto a hip rather than sitting squarely. Worth noticing if it's new behaviour.

3. Reluctance to jump (when previously willing)

Skipping the couch jump. Hesitating before the car. Looking at the bed and pausing. Even if they still jump eventually, the hesitation is a clue.

4. Subtle gait changes

Walking with the head bobbing slightly. Pacing rather than trotting. A "stiff" gait in the first 30 seconds of walking. Watch your dog moving away from you — asymmetry or rear-end swaying is often the first visible sign.

5. Reduced interest in long walks

Wanting to turn around sooner. Sitting down mid-walk. Choosing the shorter route home. These are commonly attributed to "the dog being lazy" — they're often early pain signals.

6. Sleeping in different positions

A dog in joint discomfort often shifts more during sleep, or starts sleeping in unusual positions to reduce joint pressure. Increased night-time restlessness is worth noting.

7. Personality changes

Pain causes mood changes. A dog who was always cheerful may become withdrawn, irritable, or grumpy when touched on certain areas. This is one of the most under-recognised arthritis signs.

8. Licking specific joints

Dogs lick painful areas to soothe them. Repeated licking of one specific joint (often a wrist, hock, or knee) is meaningful.

9. Stiffness after rest, easing with movement

The classic arthritis pattern: noticeably stiff for the first 5–10 minutes after rising, gradually loosening up. If you see this pattern even mildly, it's worth investigating.

10. Decreased appetite or grumpiness around food

Pain reduces appetite. A subtle but persistent appetite reduction (especially if combined with any of the above) warrants a vet check.

The vet check that catches it early

What to do if you suspect early arthritis

1. Schedule a vet check. Don't wait. The earlier you start management, the more you preserve.
2. Start joint supplements. Green-lipped mussel + glucosamine + omega-3 daily. Most NZ vets will recommend these even before prescribing medication.
3. Audit the home setup. Orthopaedic bedding, non-slip mats on hard floors, ramps if needed.
4. Adjust exercise. Shorter, more frequent walks. Avoid weekend warrior pattern.
5. Weight check. If overweight, this is the highest-priority lever. Even 1–2kg loss makes a measurable difference.
6. Re-check at 6 weeks. Note what's improved, what hasn't, and adjust.
