Does anyones chi sleep a lot? Because Dusty sleeps a lot and I'm worried about him. He plays a lot and he eat. But when I go to school my husband says Dusty goes in the room ans sleeps for 5 hours he only wakes up to go to the bathroom and to eat. Now when I get home for school his ready for play time and he doesn't leave my side. Please help me. Do I have to take him to the Vet?
