I have a 9 wweek old male Yorkie, he has been walking around the entire downstairs of the house for hours now and he only will lay down for a minute or 2 before he gets right up again. He had his first vet appointment today and they said he was healthy along with his sister. We are all very worried. Please, any advice?

Did he receive vaccines? If so, he may be having a vaccine reaction and this is how he displays discomfort. I would call the vet back and let them know he is acting strange after his visit.
