Is an ultrasonic no bark device harmful to my parrot?
I bought "bark off", a small device that can be used as needed inside (or carried in your pocket outside) to distract your dogs from "nuisance" barking. When you turn it on It emits a sound humans cannot hear but dogs can hear. Can my bird hear it? Is it possible to damage his hearing or cause any other ill effects? I don't want to try it until I find out.
