Rocky the chocolate lab in my profile pic is very vocal. I also have a yellow lab named Turbo who happens to be the laziest animal I think I have ever owned. Turbo will eat just about anything he can stuff into his face whole. Terds, bunnies, remotes, keys, foam bedding, dead birds, any kind of edible human food. Rocky is the athlete and neurotic ball hog. He could care less about anything else in life other then chasing the ball and being in the water. He likes his food, but certain veggies such as broccoli just piss him off. He will literally stomp around the house with brocolli in his mouth and growl, huff and puff at you. They both are expert crop dusters and have no shame with sharing their stench, they will also burp in your face and actually blow it at you. So yeah, I totally understand the " defective dog" thoughts.
