Here's a touching story about a brave mutt taking a coupla bullets to save his master during a home invasion.
This is one of the few cases in which the term "animal companion" actually has some validity. My nemesis Derek Sapphire likes to describe his pet moggy Jocelyn as such. But I reckon if Derek ever found himself in such a life-threatening situation, Jocelyn would be hot-pawing it outta there. The inverse would also be true -- Derek would never endanger himself to protect Jocelyn.
They're both lefties, you see. They always think of themselves first.
