I believe that all Yorkies are different personalities ... our Toto has played at "warp" speed since we brought her home at 16 weeks. In the beginning she did sleep lots more than she played ... they are so high energy that they just seem to be drained after playing hard! Is he eating well? Is he alone a lot? It's really hard to guess what could be wrong. Has he begun any of his shots? If I were you I would make sure my vet is knowledgable about this tiny breed and if he isn't, I would find one who was. Also, if he isn't eating well ... since she is such a picky eater, we give Toto the vet formula NutriCal ... that assures us that even if her appetite isn't good, at least she is getting all the vitamins and nutrients that she needs. Please keep us updated on his progress ... hope things look up!
