Why is my senior dog limping, dragging his back leg, and it's swollen?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 10 years and 4 months old

My chocolate lab is 10 years old and today he has started limping and seemed to be dragging his back end on one side when he gets up from a nap. As he walks around it seems to ease but on inspection of his back legs. One is much larger than the other around the muscle on his upper leg and it is solid around the muscle area.. There are no lumps as such though. He is probably slightly heavier than he should be but not massively overweight

This is probably due to hip disease (arthritis), the larger leg is probably not the bad side, the problematic side is usually smaller due to muscle atrophy as the dog is favoring his good leg. i advise you to take Mocha to the vet ASAP, the vet will perform a physical examination, he will probably need to be put on anti inflammatories/pain killers permanently.
