Your baby boy is just too cute!!! I honestly think all Yorkies are adorable..but I am espically fond of the ones who have manners and is well behaved! Its nothing worse than to see a cute small dog and then realize he is a yappy little devil!! LOL
I also agree with the last comment that a lot people just like smaller dogs.When I went hunting for breeders, I would specifically ask them how big they expected their pups to be..or how big the parents were. I did not want a small Yorkie because of all the health problems I had heard about. Chloe parents are 5 pounds and I am okay with that, but I would had also loved to have had a Yorkie who parents were a little bigger! Where I messed up was I went to visit the breeder to just "look" and fell in LOVE!!!
