Both Sneakers and Becca (they are Bro/Sis) came from a Friend of mine, which most call a "Back yard Breeder", though I'd like to refer to He and his Wife as "Hobby" Breeders.
They only let their PB/Registered pair have one Liter a year, and I had to put my name on a List, and wait for over six months for Becca (my most recent) His pair have a good reputation for very healthy pups, and.... well.... just maybe I'm going get a third Dog from him in a year or so. Haven't decided if it will be Female or Male yet, but you know how it goes. Once you get one then it's "Katy bar the Door" !
I've owned a LOT of Dogs in my life, but none even come close to having the intellect and intuitive ability of the Yorkshire. Most judge animals on how many tricks they can teach them, but as you should know, there's a lot more to that, than just sit, stay or lay down.
I could literally write an Essay on some of the things my two do which is just flabbergasting as to how they can think things through.
But, I'd be preaching to the Choir, wouldn't I
