Just the other day I went to look at some registered pups from a breeder reg with ANKC.
She had 50 plus dogs in cages....
She does all the paperwork, tests (bare minimum), and the dogs are shut up in those cages forever, basically.
So - she is registered and can offer you registered pups - but in no way is she ethical. NO.WAY.
An ethical breeder cares for his animals and looks after them, and is proud of what his Kennel produces, and stands by the dogs.
This is one of the reasons why its better to do research/detective work (for lack of better word), ask around, and go and see the pups yourself, or send someone to do it.
