Where do pet stores buy their dogs?

Shelby Marlo, CPDT (Animal Behavioral Specialist, Professional Dog trainer) gives expert video advice on: Where do I go to get a dog?; Don't shelter or rescue dogs come with too many problems?; Do dog breeders provide the healthiest dogs? and more...

Pet stores most likely get their dogs from pet mills, and the reason is that most reputable breeders will not sell to a pet store. However, what I have been finding and again, where I live in Los Angeles and Hollywood, is that it's an area where it is very affluent, so I am finding there's better quality pets that are in the pet stores these days. That's not to discount the fact that in many, many states, there is still horrid conditions for dogs in pet mills.
