Ringtones for Dogs?

So I saw this come through the Twitter wire and found the concept just preposterous enough to actually click on the link. A Japanese company is actually marketing ringtones that are out of the audible range of humans and are catered to our canine friends. Obviously one would question how useful such a technology could be. If I can't hear it, why buy it.

Here are some uses for such a technology:

• You are upset with your significant other and need a distraction. Issue the "bark incessantly" ringtone command and you're free to give way to the canine distraction.
• You want to impress your house guests and secretly activate the "Beat It" ringtone to which your friend with paws is taught to moon walk and possibly lick his unmentionables in tribute of the gloved one.
• Your book group is over discussing the latest Grisham novel "Appeal" and with every mention of the word "lawyer" you activate the ringtone that commands your furry friend to flatulate.
• Finally, and for no good reason, you just want to laugh and activate the "Chicken Dance" ringtone to which Rover decidely performs this timeless polka.

OK, so my ideas aren't terribly hillarious but you get the point.

What ringtone-dependent ideas can you come up with that could be useful for man's best friend?
