I SOOOOOOO do that too. thank you for making me feel a little less crazy. my dog, benson, has very strong reactions to music. My playing he either loves, or it bores him--he always curls up in a ball and falls asleep when i play. There are records he really likes--he'll come to the room from whever he is and hang out...there are others that will make him leave instantly...i put on some Art Ensemble of Chicago once and he growled at my infinitys! I will never forget hanging out at one of chicago's cool dog-friendly bars one night and a sorta wacky lady struck up a conversation with us. somehow the topic floated towards the fact that her german shepard (who was with her, chillin') was a big bob dylan fan. to prove this, she put "hard rains gonna fall" on the juke, and the once silent dog sat up at attention, and then "sang" along with the whole song. admittedly, it was cool for about 30 seconds and then got really irritating, but a fun story nonetheless.
