I like theo myself
I am in TO as well. just looking into getting a yorkie - there is a little 5 month old who is only 2.5 pounds that I am considering.
Where did you get your puppy? how much does he weigh at 4.5 months old?
How big was your pup when you got him?
Do you keep him in a crate or does he roam free in your home?
does he bark alot? that is my only concern. I am SO excited to get my very own yorkie! I am going to name mine Blue if it is a boy and Abby if it is a girl.
