What is wrong with Buddy?

One of the reasons I like the breed was
because it was small, so much for that, another was it was a house
dog. So much for that as well. It's cold out and the colder the better
he seems to enjoy being outdoors.

It's driving me nut's. I have to drag
him back in after a 15-20min walk in the bitter cold. It was 19 degrees
out this am, I was freezing he was pulling me along like it was 80 degrees.
His paper's state Yorkie, he looks like a Yorkie but could he really be
Siberan Husky in disguise? Everything he suppose to be he's not

I know there's always an exception to the rule but why does he have
them all

Good thing I love this big boy
