Why is my senior dog suddenly having trouble walking and collapsing?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 95 lbs

My dog is a 14 yr old 95lb black lab. In the last month I noticed his black legs seem to collapse and he has trouble walking. When it happens he has to drag his back legs. He can no longer get on the couch or walk at all on tile floor. He does not appear to be in pain. What could cause this?

I'm sorry Buddy isn't doing well at the moment! He is a senior large breed dogs, and musculoskeletal problems such as hip dysplasia and arthritis are common in these dogs. Those would both cause him trouble walking. He could also have a problem with his back. Even though it doesn't appear he is in pain, dogs are very stoic and this will be painful for him. I would have him seen today by a vet for a physical exam, lameness exam, and possibly x-rays. This test will help the vet diagnose what is causing his symptoms so he can be treated. He may benefit from pain medications, which the vet can prescribe. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given.
