My dogs protected me when a 60lb snarling asshole dog ran out from his yard and focused on me. The smaller alpha 15lb stepped in front of me while the 20lb slipped his leash and jumped the 60lb bastard and sank his little sharp teeth in it's neck. It retreated with my dog on his heels nipping. This dog also hates shitskins and growled at a spic who commented that lil' dog can't protect you. I had to drag him away from killing that spic. Cat would just go over and rub their legs. They have no loyalty at all.
