There's nothing wrong with the dogs, Beau. As in, it's not their fault and they're all worthy of our love. But we need to prevent them from ending up in pet shops. Lots of dogs bought in pet shops get lovely owners and a great life. But a lot of them bought on a whim end up in shelters. Or bored and frustrated, alone in a backyard.
And they are often bred without any regard for their or their parents' wellbeing, which is also very wrong. If we want to improve the fate of dogs in this country we need to stop the kind of breeders that usually supply pet shops and also check out new dog owners to try make sure they are committed to care properly for their dogs.
