Thank you all. After reading your responses I've decided to get him neutered. I was only considering breeding him so that I could have one of his puppies. Your advice was correct, I've don't have much experience breeding small dogs. I have owned two toy breeds in the past but had both spade. I was thinking it would be good for him to have another dog at home he could play, but later I will look into buying another yorkie. I won't be getting him neutered soon though since he still has all his baby teeth. His little balls have dropped though and he is always humping things?? Thank you for your help.
