I posted this earlier on another thread...
I just watched the show and thought they did a pretty good job. The only other thing I wish they would have touched on is the that these puppy mills end up selling sick puppies because of their breeding practices (or lack of it). I wish they would have mentioned that responsible breeders check their bitches and studs for disease and congenital defects and don't breed ones that have any. Also, they didn't mention how many are being brought in from other countries - like Mexico - and sold out of the trunks of cars!!! Or the trauma that these puppies go through leaving their Mom's too early, traveling from the puppy mill breeders to puppy millers like The Hunte Corp and then on to Petland!!!! 
I cried and continue to cry for all of these animals...
