I thought about breeding Hobbs bc I really wanted another yorkie that was as much like him as possible, and I figured that his offspring would be as close as I could get. But then I thought about getting one of Hobbs' siblings from a subsequent litter. I contacted his breeder and luckily Hobbs' same parents were prego with another litter!
So, if you are like me and want another one like the one you have now, have you considered maybe getting one of his siblings?? I know that non-neutered males can be somewhat of a pain and I know that breeders recommend that the male be smaller than the female. Just a thought......I'm no expert.
Good luck in whatever decision you decide to make!
