Thousands of puppy mills operate around the US. Even more pet shops live off of neglected dogs.
My friend has a Cavalier King Charles Spaniel named Rosie. Rosie was from a puppy mill, but a rescue dog. She had been forced to have puppies four times.
Imagine you're a young dog. You know nothing of the free life dogs normally have. This is replaced with a crueler image of a tiny, dank, smelly cage. Your only hope is that it ends soon. Your only contact with humans isn't positive.
This is the life of a dog in the puppy mills. Help save dogs who might never get the loving home that they deserve.
