I hear what you are saying applesmom, but I think we also need to add the difference from a "hobby breeder", and a " backyard" breeder. A " hobby " breeder is one that does the genetic testings on their dogs also, may not be actively showing, but dedicated to their breed, and breeding only good representatives of the breed.
The " typical backyard " breeder- is one that well I have a male and female cocker spaniel- what the heck- we could have puppies ... There is no attempt in either good parents of the pups, or an attempt to get good representatives of the breed. Shelties are a perfect example of this. Shelties can easily be too big- not the smaller ones seen in shows, but more of a working sheltie. Size aside- at least some try to make the dogs healthy- others do not-
Now posing question at you ( I already know my answer..) BUT- IF there is a person, with two shelties, both too big out of standard, but checked the hips, hearts, thyroids, - and breeds them- does this still fall under as a "backyard " breeder, or now 'upgraded' to a hobby breeder?
