Ah yes. My four legged, fur coat wearing, flea bag partners.... They are like heat seeking chainsaws. I have watched as they have literally devoured people. I swear to God I looked at a suspects leg and thought, "holy shitt, where's that guys calf muscle?" The only thing left was that mutts bloody smile.... and they do smile!!!
K9's are not to be looked at as pets or even animals. They are tools that have been honed to [near]deadly capacity.... That being said, they are only as good as the handler. I have seen waaaaaay too many wasted beasts. They were as worthless as their two-legged counterparts, just waiting on retirement.
