Perhaps you and the other owners of dogs from her should all write and sign a letter saying that you are all concerned, and that perhaps she should just stop breeding these dogs, as "problem children" are the inevitable result.

Most breeders want to improve the breed, she is harming it - and its reputation - considerably.

I am glad Happy is with you - someone who is at least trying to understand, and hoping to help, with Happy's inherited difficulties. Give her belly skritches for me, okay?
