Sounds like someone needs to get their friend a pitbull. Treat one of those like that and they'll snap, and take a lovely bite right out of him. Just to be clear, I'm not saying pitbulls are bad dogs. I'm saying this guy needs to be taught a lesson. Any dog will snap if it's being abused too much. Dogs aren't bad, bad owners make them that way. What he really should get is a visit from the cops, maybe to scare him straight. Edited for a little more clarity. I have no tolerance for animal abuse. I'd sooner beat the crap out of the guy, and then ask him how he likes it.
