My 7 month old chi has started to limp for a couple of minutes after he first wakes up. He does not seem in any pain at all - it almost like his leg has gone to sleep. He tries to run about but its the same front leg that gives way umderneath him. After a couple of minutes and a stretch he is totally back to normal and its never a problem at any other time.
Ive visited the vet who found nothing wrong with his legs after 20 mins of manipulation. But no xrays and he didnt see him limp (its only after sleeping). I've now got a video to show the vet (i think they thought i was a bit neurotic to be honest) but has anyone known anything similar?
