I would just like to say my bit, I work for a breed rescue & come a cross a west wales breeder selling whole litters to a pet shop in London. I called the kennel club & told them that we had had 3 of these dogs in rescue from the same pet shop.
Under the kennels clubs own terms & conditions it states that no breeder should sell too a commercial outlet, when I asked them about this there said they cant enforce it theres nothing they can do................
So in my opinion theres little point in having ethics
