maybe you should have him vet checked, if he's limping , even tho it clears up the next day, it seems to be re occuring, I would want to know 'why' he's limping. Could be nothing , could be something that you might be doing more damage to by over exercising him.
Dogs don't limp for no reason. Dogs can also be quite stoic and will not stop unless we make them. Some dogs also have high pain thresholds..
I guess I'd want to know 'why' he's limping and I would want a vet to tell me why..
