What is your definition of "sleeping a lot". I think dog's at any age sleep a lot, especially puppies.

How does your Sr. Yorkie act when awake? Is he eating well? Does he like toys? Does he seem lathargic? I know in another thread you posted that he is having some teeth problems. Does he seem ill to you? Maybe have an infection from his bad teeth?

So many of us I think might have a different definition of "sleeping a lot". So, maybe how many hours a day is he sleeping and is he sleeping all night long is my question about your little guy.
