Have they bred an ultrasonic breed of dog yet?

I think all of those ultrasonic things are, pretty much, snake oil.

Can anyone suggest a good deterrent that is ultrasonic?? I bought one and
can
hear the ultrasound and when it rained today I heard it in alley window
coming
from the backyard. I hear that Cat Stop is good. Any suggestions??


Thanks,
