The stairs are a test: reading your senior dog’s joints

Small changes in how they rise, climb and settle say a lot. Here’s what to watch — and what to ask your vet.

By the AminoTails Science Team · Reviewed by our veterinary advisory board* · August 2026

Key takeaways

  • The earliest joint changes show up in transitions: rising, climbing, settling.
  • Body weight is the single biggest lever you control.
  • Film the stairs once a month — it turns a hunch into something your vet can see.

The first signs are quiet

Dogs are good at carrying on. Joint changes rarely arrive as a limp; they arrive as a pause. A slower start after a nap. A beat of hesitation before jumping into the car. A walk that ends a block earlier than it used to.

Other small tells: sitting with one leg kicked out to the side, licking at a wrist or knee, stiffness that eases after a few minutes of moving, or a new reluctance on slippery floors.

The stairs test

Pick one staircase and film your dog going up it once a month, from the side, at their own pace. Watch for bunny-hopping with both back legs together, pauses on the landing, or a shift in weight to the front.

The point isn’t to diagnose anything at home. It’s to give your vet a clear before-and-after instead of “I think he’s a bit slower?”

What helps, day to day

  • Keep them lean. In a fourteen-year study of Labrador retrievers, dogs fed to stay lean lived around two years longer and showed joint changes later than their littermates.
  • Shorter, more frequent walks beat one long weekend hike.
  • Grip matters. Runners on hard floors and a ramp for the car save a lot of small strains.
  • Swimming is excellent low-impact exercise, if your dog enjoys it.
  • A supportive bed away from drafts makes the first steps of the morning easier.

Where supplements fit

Supplements are support, not a substitute for any of the above. Joint Plus pairs daily cartilage support from Cartalax with weight-based dosing; Joint Pro adds BPC-157 for the tendons and ligaments around the joint.

Whatever you choose, give it six to eight weeks of consistent daily use before you judge it — and keep filming the stairs.

When to call the vet

Sudden lameness, a swollen joint, crying out when touched, or refusing to put weight on a leg are reasons to call your veterinarian the same day — not things to watch and wait on.
