I am pretty sure that I've decided we will go through with the neuter. I would love to breed him....but I think that some think he is too small to breed. I also don't want him to live with the frustration of always feeling like he needs to find a mate, and I wouldn't want him to get a female pregnant accidentally. I figure if I want another yorkie, I will just have to buy one or hopefully adopt one that is in need of a home!!
Thank you to everyone for their advice and input!
