Breeding is alot more then putting 2 dogs together. I don't know as you only asked if he is old enough to breed..... but have you done this before and with a yorkie? Have they been tested for any problems they may or may not have? I think you need to have them fixed. We have to many puppies in shelters now. And if you want to be a yorkie breeder take your time and learn what is involved to be a good breeder. Please look at the breeder forums on yt and look at some of the past threads you just may change your mind.
