I have loose grasp of what makes a good breeder a good breeder, health testing, contract with spay/neuture and health guarentee included, but am curious about one point. If a breeder health tests all their dogs, waits till they are 2 plus to breed, and does everything else right but DOESN'T show are they still considered a byb? Where does the distinction lie? Does the # of dogs change status as well as not showing? What if all those dogs are top of the line? I'm just curious how a person can know the difference between a good breeder and a byb. I hope I can tell the difference by now between a mill and a good breeder (lord I hope so) but the line seems a lot more fuzzy between some bybs and truly good breeders. Does anyone have a check list for potential puppy buyers to help us know what we should be looking for as well as avoiding?
