Dogs fear me

Or to be more accurate, they fear the high B on my whistle.

Was sitting in the car, getting in one last practice before going into class. Dude walked by with a terrier on a leash just as I was doing the second half of O'Keefe's Slide, which has a mess of high a and b's. The dog stopped short, whipped around and stared at my car, all at attention. Dude turned around like wtf?

Me - slid down to hide behind the steering wheel.
