Sorry, I've personally seen no-kill shelters I wouldn't give a dead hamster to. They warehouse animals in substandard facilities in packs. Weaker dogs were killed when the pack turned on them. Dogs were fed by throwing in large amounts of food in one or two places, so that the strong ate, and the weak got weaker.
I've also seen a place that bred dogs commercially(mostly dachunds) and they had well over 100 dogs. The kennels were well made, the dogs were clean and healthy. The puppies were fat healthy animals that would make good pets for people.

But by most people's standards, they would STILL be labeled a puppy mill. Never mind that the dogs are healthy. Instead of focusing on labeling breeders, why don't you focus on enforcing laws that already exist for humane care for the dogs? I.E. appropriate shelter, vet care, food and water.

I've seen pet stores that take kittens in, then sell them. I don't mind it, as long as the kittens are vetted and healthy. If you want a kitten for free in front of the supermarket, go get it.. then spend the $200 at the vet for all the stuff a kitten needs and hope that it's not sick already. Get a well vetted kitten from a reputable sho, shelter, or pound.. and you usually pay $60 and you get a kitten already checked by a vet. The shop that sells the kittens for $60 that has vetted the kittens doesn't make a ton on the kitten, anymore than they make a ton on the puppies they sell. They make their money on the accessories. The puppies and kittens draw in customers.

IF the shop is taking proper care of the animals, there should be no onus on them for selling puppies and kittens. They should also be making certain that their suppliers are treating their dogs, cats and the puppies and kittens properly as well, i.e. clean, fed, watered, sheltered.

Too many times people just automatically label ALL breeders as bad, either they are "backyard-breeders" or "puppy mills". Pick one, the only difference is number of animals. No one waits to see if they are caring for the animals properly, it's still a "bad thing" just because they breed.

HSUS only wants to outlaw all animal ownership INCLUDING owning dogs or cats as pets. They've already stated as such in some of their literature, and that's their goal. They'll just do it in a sneaky way so it'll get past all the blind doners who think "Ooo, a picture of a puppy, they must be good!" and hand over their money, and then blindly believe whatever they're told, because the HSUS says "humane" in it.. they must be right.
