I have a toy poodle (4ish pounds) and Tucker, Tucker picked up on my poodle's little dog syndrome. He was fine untill she would start going into attack mode. Lexee (poodle) has gotten herself in some trouble by being so aggressive towards bigger dogs had has been bitten twice, thank god they were just minor bites but it hasnt slowed her down any. Everyone at my inlaws house has big dogs so I have to keep my dogs at home when we go there to visit. She has no problem with little dogs though..
