Why is my old dog suddenly limping, falling, with no visible injury?

Updated On September 23rd, 2025

In the past 24 hours my 13-year-old lab mix has gone from running and playing to limping with his front paw not coming all the way forward when he's walking. This causes him to fall over and I can't see anything wrong with his paw on the outside.

I'm sorry to hear your dog is limping! It's no fun to see them in pain :( I would recommend having your dog looked at by your regular veterinarian when you are able. Sudden onset lameness can be due to any number of things, from a strain/sprain to a fracture or dislocation, or ligament damage or even a bone tumor (definitely more common in older dogs). Your vet can do a thorough exam or your dog and try to determine which part of the leg is painful. They may recommend X-rays to check for some of the problems listed above, and they may prescribe some medications to help with the discomfort. Until you are able to have your dog seen I would recommend restricting his activity and only taking him outside on a short leash to use the bathroom.
