My 8 month old lab had been limping every now and again with his hind leg so we took him to the vet, had an x-ray and his joints seem fine.
The vet told us to rest him with 2 10 minute walks a day on the lead. We've been doing this for about 6 weeks now, gradually increasing his walks and he's been fine so yesterday I allowed him off his lead for the first time. As he's a young lab he's had a LOT of bent up energy so off he went as fast as his legs could carry him. All seemed well until we got back, after he'd been in his bed for about half an hour, then when he got up he was limping again. This only lasted for 20 minutes or so and he seems fine again but it's frustrating not knowing what's wrong with him.
The vet says she thinks it probably a pulled muscle that will get better eventually but I thought you guys may be able to offer a second opinion.
Basically he has only ever limped once he's rested in bed AFTER a run. Even then the longest it's lasted was probably 2 hours but it does seem to happen every time he has a long walk off the lead.
Any ideas
