I would love to have a Biewer one day too! They are adorable. Sorry, I don't know any breeders. But I have two boys, and I've never had any problems. If you have a laid back dog, get another laid back dog. You have to match their personality. I find the sex doesn't matter but you can't have a energetic one and a laid back one. It usually doesn't mix and someone will end up getting aggressive. Like states above the next pup I get I want a girl just bc I've never had one to dress in pink and bows
. Good luck in your search!
