Dogs Breeding in Puppy Mills

In order to maximize profits, female dogs are bred at every opportunity with little to no recovery time between litters. When, after a few years, they are physically depleted to the point that they no longer can reproduce, breeding females are often killed. The mom and dad of the puppy in the pet store window are unlikely to make it out of the mill alive, and neither will the many puppies born with any indication of imperfection.
