WELCOME TO YORKIETALK TO YOU AND ZEKE 
Welcome to YorkieTalk. I am so glad you joined our growing community. Ten week old puppies DO sleep alot. They eat and drink, poop and pee and then play until they collapse to sleep - then they start all over again. The big question would be when Zeke is awake how is his activity level? Is he playful, is he eating and drinking, peeing and pooping? If so it sounds like he is a perfectly normal little Yorkie.
