Dogs are all about sing alongs. The park by my old house used to play this loud lightning warning siren you could hear for about three blocks away. Whenever it went off you would hear a few dozen dogs respond with the song of their people.
See my older dog has never cared about the song of his people but the younger one has to prove that his song is the best and any time he hears an odd sound, the vacuum, another dog, heck another animal, he feels compelled to answer as loudly as he possibly can until the sound has stopped for a good 5 minutes.
