i actually would like to have some info on this too. i have been researching some breeders in Toronto, but dont really know how to tell is they are BYB or not. like what if someone has a passion for the breed, but does not show? is everyone who breeds in their home and doesnt show considered a BYB? i dont care if a pup is show quality since i will never breed or show, but i also dont want to contribute to the degeneration of the breed...
