Just to be very clear, Duke has never "attacked" any human being in the eight years I have had him, and he was six months old when he brightened my life. He brings joy wherever he goes (unless you've left your trash out on the porch).<quoted text>
Don't think so. He's replying rationally, not in attack mode like you are 99% of the time. You sure you're not Duke's dog?
He certainly has killed his share of chipmunks, mice, and moles, but even then, he usually merely wants to play with them, and things get out of hand. And people have accused him of attacking cats, but those are false allegations. He loves them. I've seen him pick up tiny kittens in his mouth and proudly and protectively carry them around in the exact same fashion that mother cats do to their own younguns...that's where he learned how to do it.
I have seen him pose in a protective stance and snarl on a very rare occasion when there's a stranger approaching my son, and Duke apparently notices something amiss, but never has he attacked.
He's a good dog.
