They are not only inhumane but a disgrace and the thought they merely exist is revolting.
But reality is this, if we researched the breeders where the puppies came from (even from a pet store) and the complaints or citations they had received. they would not make the money and would have to move on to another criminal activity to survive
There was a large chain pet store who unknowingly (hmmm) was buying puppies from just such mills and when it was brought to their and the medias attention stopped immediately (imagine that) Different counties began shutting the mills down or citing them, (Yes! One for the puppies)
The investigation and report was in 2008 involving Petland, dozens of breeders, The Humane Society, and MSNBC and took months of long hard work. Great job guys and all due to one person trying to make a difference.
FYI some of these mill puppies were selling for as much as $3500 so don't think for a second that just because they cost more means they must be from a good breeder (total misconception)
People assume that because the puppy comes from a "known" pet chain that it is a good breeder (totally not true) Remember companies large and small are usually in it for the money.
So the moral of this "should have been a hub" DO YOUR RESEARCH!
