My definitions of a bad breeder are;
NO health testing
NO spay/neuter contract
NO interest in the puppy after it goes to it's new home
Will place a puppy/dog with anyone handing them $$
Will not take back or help re-home a puppy if needed
Breeds just to make some money
Those are just a few that come to mind.
