Ultrasonic Dog Barking Control Device

Goodbye To Endless Barking. . . .  The Ultrasonic Dog Barking Control Device teaches your dog or your neighbors' dog to stop barking, giving you peace and quiet.  Stops dogs from barking by safely emitting ultrasonic waves in a gentle, friendly way that is harmless to both people and pets.

Much like a dog whistle, the ultrasonic sound is harmless yet annoying, which causes the dog to stop.  No more annoying barking.   Use this anti-barking device to train your dog to be quiet. Safe for small, medium, and large dogs.  Adjustable Modes allow you to choose the appropriate level of ultrasound depending on the size and age of the dog.   This device solves the problem of noisy dog barking.  Turn on the unit and turn off the barking.
