Why are there health problems with puppies from mills?
Many breeds of dog have conditions that they are prone to, such as hip dysplasia, chronic skin conditions, overshot jaws and heart murmurs. Good breeders test their breeding dogs for these conditions prior to mating. Puppy farmers do not and, as they have no contact with the puppies once they have left the mill, they have no idea what genetic defects they are continuing to breed into these puppies.
