I used to like to play Pink Floyd's "Dogs" track for my dog to watch her look at the speaker, furrow her brow and cock her head trying to figure out the electronic barking noises. Classic dog body language for WTF?!?

Tyler (1989-1992) would howl along.

I always wondered what the reaction would be to "Several Small Species Grooving"
