My dog hates fat people. She's still a pup, 9ish months old. American bulldog/pit mix. All white, one blue eye, one brown. She stands out and is a person magnet. She absolutely hates fat people. At first I thought she was just skittish around some people, randomly. She's absolutely fine and friendly around most people, but she loses her shit when a fat hand tries to pet her. And the fats are just drawn to her for some reason. She's a good dog, she'd never bite, but she will bark her silly face off protecting her mom. So we're driving last night, on a road with tolls. One of these toll booths contained a literal toll troll. I think she must be confined in that small booth because she took up the entirety of it. I would have taken a picture, but I was busy trying to keep my dog from jumping into the troll booth. The troll was oblivious, and just kept on talking baby talk to my pup, wtf. My dog hates you.  It can get kind of embarrassing at times, but it is what it is. I never taught her to bark at or dislike any people, especially because of what she is, and I don't need that sort of trouble. She just knows.
