Very effective. The dark brown female is very protective, as all pit bulls are, but the yellow male is a Shar Pei / pit bull mix. He's always on guard duty and will bark at anyone whogets too close and looks out of place. He's a very lovable and friendly dog, as all pit bulls are, but he was attacked by a 130 pound unneutered male Italian Corso and fought him off in less than seconds. An amazing dog you don't want to piss off.

Nope, we don't need pepper spray or guns. Only dog food.
