Yes, a few dogs don't like the sound. It's not that unusal.

And, as I tell my students, I don't care what you call a behavior as long as you're consistant. If you want to call it Beekabeeka, have fun.

I've always toyed with the idea of making up a very strange language and going into the agiity ring with my dog calling out quite silly commands. Of course, i won't do it. If something were to happen to me, my dog wouldn't be able to work for anyone else!
