Congrats on your new puppy! As far as the breeding, I am assuming you mean "very small" by saying "teacup". Breeding can always be dangerous, but is even more so with a tiny dog...a lot more so. I think friends are looking at cute puppy pictures of your new baby and just "want" one just like it. They have no idea the cost and danger you will entail if you choose to breed. I could run on and on, but I want to tell you that I honestly wouldn't recommend you breeding your new girl. Let all your friends come over and love on her!!
