Puppy mills are incredibly horrible places for dogs. The dogs (sometimes hundreds of them) are kept in cages too small for them to move around in, a lot of the time stacked on top of each other allowing waste to drain down on the dog below. The dogs sit in their own waste constantly, never taken out for walks, and never bathed. These dogs are never socialized with humans or other dogs and the females are required to produce litter after litter without any care for the mother or baby's health.
The worst part of all... Puppy mills are NOT ILLEGAL. So, we have to fight and MAKE THEM ILLEGAL. Do your part, and sign the petition!
