"Just a generation ago if you went near a dog when he was eating and the dog growled, somebody would say, 'Don't go near the dog when he's eating!, what are you crazy?' Now the dog gets euthanized. Back then, dogs were allowed to say, NO. Dogs are not allowed to say no anymore...They can't get freaked out, they can't be afraid, they can never signal 'I'd rather not.' We don't have any kind of nuance with regard to dogs expressing that they are uncomfortable, afraid, angry, or in pain, worried, or upset. If the dog is anything other than completely sunny and goofy every second, he goes from a nice dog to an 'AGGRESSIVE' dog."
