They actually released a single around Christmas time. Of course, humans can't hear a thing but dogs reacted to it in a variety of fashions. Most just barked and seemed happy wagging their tails, some ran around barking and in a few rare cases the dog went a little bit schitzo. In one reported case the dog tore apart the sound system it was playing on. The track got a little bit of air time on some radio stations here too, just as a novelty, and yes I "heard" that play.
Apparently sales of it were so good that it made #1 in the charts for a short time. lol!
