I've HEARD that if you baby a male too much, they won't turn out to be a breeder. I've had breeders and also my vet tell me this. We were worried that Chester wouldn't perform because I had babied him all of his life. But, he proved all of us wrong. Now, a friend's mom just bought a 2 yr old male yorkie and she babies him to the point that if anyone comes around her, he tries to bite them. My guess is he considers the lady his mate.
