Welcome to YorkieTalk! Small breed puppies should stay with there moms until 12 weeks so you might have a few issues with potty training, bite inhibition, and socialization. You need to make sure you know the symptoms of hypoglycemia which is another problem small breed pups can get and you should keep some nurtical on hand. Also remember to get your pup to the vet within the next two days for a vet check up. I also suggest you keep your pup away from other dogs until he is fully vaccinated. One more thing stay away from treats made in China many of them have been making dogs sick and killing them. There is great info that can be learned here so grab your wife and join the club
