Would have been better to just require a license with required facility monitoring by the government or 2rd party agency for all dog breeders especially the amatuar breeders. Additionally require papers on all dogs sold period not just pedigrees. Most dogs are already damaged from the puppy mills/breeders before they even hit the animal shelters or pet stores. Control at the source.
