Anyone who has bred a litter of puppies is by definition a "breeder". That is not an endorsement of quality or care. All breeders are definitley NOT the same.
Pure Bred = Well Bred - FALSE - All purebred registered puppies are not equal. Papers and proof of pure bred status does not necessarily mean a quality puppy. While choosing a breeder who sells Canadian Kennel Club Registered puppies is certainly a good start, not all of these are as well bred as others.
