I have a question for ya..I used a stud on my girls but i'm going to be buying one sometime in the near future. My smallest female is 5 and half pounds the biggest is 6 and a half pounds. I was the proud mama of a boy that died just before he turned one and he was around 3 and a half pounds. I never had problems with him as far as his size but i've heard that some have had problems with the smaller yorkies. Anyway i'm trying to get to the point here lol..I was wanting to get a male that was between 3 and 4 pounds to breed to my girls..Do you think that is a good size or will I be asking for alot of problems due to one being that small? What do you think is a good size to have for a yorkie stud?
