My least favorite breed is the Chow- really an ill tempered bear cub- Little bastard took a chunk outa my leg, after I house sat and fed the creep for a week.

I hear you. The only dog to ever bite me was a Chow as well. Weird dogs, unprovoked attack, too.

If my knowledge serves me, Chows were actually bred for fighting and guarding, while a Rott originated as a simple farm/all around utility dog in their native Germany.
