Have a question for the long time Yorkie people, I have my first Yorkie, Keno 7 months who is tall,,,,12 inches and skinny. His legs go on forever. He has a perfect coat and is from a 6lbs male and 7lb female. I saw both parents. My question is how did this happen. Keno is neutered and goes at 9 lbs.

He is smart and a keeper. I wanted a small yorkie, 6lbs or so. But, like I said he is a keeper, so he is just right.....
