"Where did you get your dog?" is what I often ask people on the streets during a casual pup greeting. Many dog owners have no idea where their dog REALLY came from.
Your dog is from a breeder? OK. Did you meet the dog's parents? No? Your dog is from a puppy mill.
Was it hard to get the puppy? No? Your dog is from a puppy mill.
Did they ship your dog to you? If so, your dog is from a puppy mill.
Your dog is from a pet store? No, your dog is from a puppy mill.
Your dog is a rescue? Great, let's be friends!
As a mom to three former puppy-mill breeding dogs that were all rescued at various stages of life, I have witnessed firsthand the mental and physical toll the mill took on my dogs, which is why I am very vocal about adoption being someone's only option for welcoming a pet into the home.
While we are acknowledging that factory farming of farm animals is not a best practice as a society, we are slower to recognize the cycle of puppy mills, which is essentially factory farming for dogs.
