Sounds somewhat like my Dex, 2yr. Although, he never bit anyone, if he is on my lap and DH goes to touch me or put his face near him to kiss him, FORGET IT. He is everything you explained about Snoozles when someone comes to the door,or even startled??? Halloween i though he was going to give himself a heart attack from over reacting. We ended up going outside w/ him on a leash, but that didn't get any better
