I have a 3 lb stud and I use him on my 4lb and 5lb females. Another thing to consider when breeding is how big are the parents of the stud dog? How big are her parents. I have found a dog can be small but still produce larger pups than what you want because he/she was actually the runt of the litter but has bigger siblings and bigger dogs in the background. When I went looking for a male pup for a stud dog, I looked at the other litter mates, the parents and also the grandparents if they were there.
