Dog Limping: Causes and What to Do

Sudden vs gradual limping

A limp that appears suddenly often follows an injury, a torn nail, a cut pad, a strain, or something stuck in the paw. A gradual limp that worsens over time more often points to arthritis or a developing joint problem. The onset helps narrow the cause.

Common causes

Paw injuries, insect stings, muscle strains, ligament tears like a cruciate injury, joint disease, and infections can all cause limping. In large or senior dogs, arthritis is a frequent culprit. Some causes are minor; others need prompt care.

What you can do at home

For a mild limp with no obvious wound, rest and restricted activity for a day or two may help; check the paw for cuts, swelling, or debris. Never give human pain relievers like ibuprofen, which are toxic to dogs. Keep your dog calm and limit stairs and jumping.

Supporting the joints

For dogs prone to arthritis, a joint supplement like [Cosequin DS Plus MSM Joint Supplement](/products/cosequin-ds-plus-msm-joint-supplement) may support long-term joint comfort as part of a vet-guided plan. Supplements support, but don't replace, proper diagnosis and treatment. Keeping your dog lean also reduces joint strain.

When to see the vet

Seek prompt care for non-weight-bearing lameness, obvious pain, swelling, a dangling limb, or a limp lasting more than a day or two. Sudden severe injury is an emergency. Your vet can diagnose the cause and recommend the right treatment.
