my Drummer has the COOLEST dogs in the world. Not sure what kind. But they never ever ever bite, and one is afraid of everything but likes to play all the time.
She'll come up and be afraid of the microphone and start barking at it, then she'll get scared of the barking from the amp and bark at that, and then start running around its awesome. THe other one is cool too, if you put your hand out for the dog to sniff it (like you are supposed to) the sog will start chewing on your arm, not a hard bite at all, but its really funny.
