well my big scary dogs consist of Foofie, a 10 lb poodle and Romeo (my boyfriend) a poodle of a whopping 4 lbs when wet. He is scared of the neighbor's cats who come sit on *his* back deck. He hates they are there, but what's HE gonna do about it! He barks viciously at anything that so much as twitches but poor thing just doesn't have it... ya know.
