I am a lifelong dog fancier. I spent 5 years as a field inspector for the American Kennel Club. I will, of course, watch this, as I have others in the past.
IMO, if puppies & kittens were not allowed to be sold through retail outlets, the puppy mill problem would take a huge hit. Most of you, would NEVER purchase a puppy from these locations, but it's done everyday through retail outlets.
Retail outlets provide folks with 'wallyworld' style shopping. Instant gratification... credit card/installment plans... AND, they won't tell you that you DO NOT QUALIFY for a puppy (because you rode in on a chopper with your girlfriend and just want to make her a present of a puppy; living in apartment; no job; 4'2' 110 lb and want a ROTTWEILER; no fenced in yard; work 80 hours a week; or other various reasons why responsible breeders/shelters discourage the purchase/adoption of a puppy).
You can continue to shut down one puppy mill after another, but unless you do something to reduce that style of MARKET for puppies, another will crop up in its place.
Many people who raise multiple breeds of dogs and more than one litter a year should NOT be designated puppy mills. I inspected many small breeders who took excellent care of their dogs, tested for genetic defects, socialized and vetted their puppies, did a good job of placing their puppies, and provided after purchase support. The first and biggest difference was they sell their puppies DIRECTLY to the public.
