Lol, I noticed that, too. Like, uh...what possible reason would a deer have for chasing a dog? Numerous times? You know deer are herbivores, right, and dogs are not, so the deer would see the dog as a predator and try to escape from it, not pick a fight? Stupid pig's sister probably told her that story once as a joke, to see if it was dumb enough to believe it...and of course it was.
