I live in NYC and want my 16 month old MALE Yorkie to breed. He is about 6 pounds and very healthy (not to mention his wonderful character). Can a knowledgeable person give me the facts as to how I would go about setting him up with a female dog. How does it work....once he has started will he want to be breeding every day? I am still on the fence about fixing him (don't feel like it is natural to change what is G-d has given him and his vet said it is o.k. if I don't have him fixed). Thanks in advance.
