7 Early Signs of Arthritis in Dogs Most Owners Miss

Arthritis affects 25% of all dogs — and up to 80% of senior dogs. But most owners don't recognize the early signs until their dog is already in significant pain. Here is what to look for years before the obvious limp.

Why Early Detection Matters

Arthritis can't be cured, but its progression can be dramatically slowed. Dogs treated early maintain mobility and comfort for years longer. By the time a dog visibly limps, significant joint damage has already occurred.

7 Early Signs Most Owners Miss

1. Stiffness After Rest (Not Limping)

The dog gets up slowly in the morning or after naps. They're stiff for the first few steps, then "walk it off" and seem normal. Owners think "he's just getting older." This is arthritis.

2. Sitting or Lying Differently

The dog sits with one leg splayed out to the side instead of squarely. This "lazy sit" is actually compensation for hip or knee pain. They may also lie down differently — circling less, or flopping down abruptly instead of lowering gently.

3. Reluctance to Jump

The dog hesitates before jumping into the car, onto the couch, or up stairs. They may still DO it — but with visible hesitation or a running start they didn't used to need. This is pain, not "being lazy."

4. Changed Gait

Subtle changes: shorter stride, bunny-hopping with both hind legs when running, shifting weight off one leg when standing, scuffing toenails on walks (from dragging feet slightly).

5. Irritability or Withdrawal

A normally friendly dog becomes grumpy, especially when touched near the hips, back, or shoulders. They may avoid being petted or snap when children climb on them. This is pain, not a personality change.

6. Accidents Indoors

A previously house-trained dog starts having accidents. They're not being bad — getting up to go outside hurts. The pain of moving outweighs their house training.

7. Decreased Activity

The dog stops initiating play, brings toys less often, lies down sooner at the dog park, and sleeps more. Owners think "he's calming down with age." It's often pain.

What to Do

Vet visit: Physical exam + joint palpation. Radiographs to confirm and assess severity. Pain scoring to track progression.

Treatment: Weight loss (the #1 most effective intervention — every pound lost = 4 pounds less force on each knee), joint supplements (glucosamine + chondroitin + omega-3s), NSAIDs (carprofen, meloxicam, grapiprant), Adequan injections, Librela (monthly anti-NGF injection), physical therapy and rehabilitation.

Home modifications: Orthopedic bed, ramps for stairs/furniture/car, raised food and water bowls, non-slip rugs on hard floors, gentle exercise (swimming is ideal).

Don't accept "it's just old age" as an explanation. Pain is treatable at any age.
