Limping in dogs

Quick answer

A limping dog is usually protecting a painful leg. Check the paw first for thorns, cuts, torn nails, or swelling between the toes. If lameness lasts more than **24 hours**, worsens, or follows an injury, see your vet — sudden hind-leg limping in active dogs can signal a **cruciate ligament tear**, which needs prompt diagnosis.

Key takeaways

  • Rest the leg until you know the cause. Short toilet breaks on a lead are fine; avoid runs, jumps, and stairs until your vet advises otherwise.
  • Limping usually means discomfort, though some dogs hide pain well. Always investigate lameness rather than waiting it out.
  • Sudden hind-limb lameness can be a paw injury, muscle strain, or a cruciate ligament tear — especially in active or overweight dogs. A vet exam is recommended.
