To even think that robot dogs would "attack" you in the same sense a real dog would is the funniest thing to me. Of course a robot dog would use missiles, guns, lasers, chemical spray, etc.
Reminds me of the book Daemon by Daniel Suarez (or its sequel, Freedom) where the automated, world controlling daemon uses robot drones with blinding lasers to semi-permanently incapacitate everyone in an area.
lol nah it should use a mechanical mouth with some insane hydraulic clamping force. And claws, why not give it some stainless razor wire claws while we're at it.
Pretty neat story :)
