My 10 month old male limps after waking getting up from a nap. Usually after running and playing hard at the dog park. Its his right front leg. limping only lasts a minute or two then stops.
I would get it checked by vet. It maybe nothing but I would get it looked at just to rule out any problems. I would also cut back on his hard play a running until I'd got to the bottom of the limping.
Definitely get it checked out as soon as possible, it may be nothing or it may be something far more serious. I really don't want to frighten you but in my experience the sooner the better then if there are any health issues they can be dealt with quickly. As @SwampDonkey says cutback on the hard play for a while, I would do more activities and training to compensate and tire his little brain. Good luck. Fingers and paws crossed.
