I have a special place in my cold dead heart for people who get dogs and then refuse to train them because "That would be mean"
I'm not asking you to beat your dog, but you can't fucking have an apex predator in your home snapping at people and thinking that's fine
I bite train all of my ferrets and even then, I always tell people that they might still nip because that's how they are, they're animals
Dog owners frequently don't even do that, they have their 80lb Belgian Malindoodle charge me while i'm walking and they're like "Oh, don't be scared, he's just friendly!" while that damn dog is snapping and snarling like i'm a giant walking turkey leg
