Barking that starts while you are at work, asleep or in another room does not have to wait for you. This ultrasonic device answers it on its own with a tone dogs notice and people do not, with no shock and no spray. Stay with your dog for the first sessions and stop if it shows distress.

As an ultrasonic dog bark deterrent, this stop barking device runs itself: automatic detection activates it when barking is detected, and the frequency adjusts from 15kHz to 30kHz. Its compact design hangs in a hallway, yard, porch, training room or on the back fence, so this dog training aid works indoors and outdoors.
