Welcome to YorkieTalk, MexChik! I believe that "Squirrel" Yorkies refers to a kennel which raises Yorkshire Terriers ... not a "type" ... our Toto was bought from "Tyava" which is their kennel name. I am not certain how to describe "Teacup" except that the AKC doesn't recognize it as a breed. They are the little tiny ones and I have heard lots say that there is no such thing as a teacup and, on the other hand, I have heard some say that there is! Go figure!!
We have some members who are breeders that hopefully respond and can give you an excellent explaination!
