When I was small, we had some neighbors over and our dog (some sort of shepherd mutt) got riled up and bit one of our guests. Just enough to break skin. It was entirely unprovoked and we put the dog down the next day. What the fuck has happened to where useless cull dogs can straight up kill and start eating someone and the owners are even potentially able to keep them? How is any level of unprovoked human aggression deemed acceptable in what are supposed to be pets?
