I don't know how many people know about these, but that is where petstores get their puppies at. We have a few where we live, they just post in the paper though. I think it's sad you have to abuse animals for profit. Puppymill dogs are also very unhealthy and sometimes deformed. The moms spend all their life having babies, and they are kepted in small chicken cages. It's so sad.
