And it's pretty much like I said. Doesn't have a pole to release the dog so he has to get close. He gets the dog loose, then instead of walking, or perhaps backing, away, he stays around to fight with the roo. The roo isn't serious, but he doesn't know what this bigger animal is going to do, so of course he faces him.
Unless you're not where you're supposed to be or something, animals typically don't fuck with you. Of course, if they do, wild or domesticated, I'm prepared to kill them, like I'd kill a person if I had no alternative. Deadly force, yo. And love otherwise....unless they don't want love, and then they can WALK.
