Ultrasonic Dog Bark Deterrent

This ultrasonic dog bark deterrent can automatically stop the bark and creates a tranquil and quiet indoor environment. You just need to put it on the table or in the corner of the house where the dog is often barking. When the dog barks, the dog within the coverage will hear a 2 second ultrasound. You can set it to turn on automatically when the dog barks, or you can turn it on manually to make an ultrasound. Your dog will associate the high-frequency tone it hears with its own bark, and the ultrasound can only be heard by dogs, which can not be heard by most of the human beings. Most dogs will reduce their barking after a few days. The device covers an area of 8 meters and is the size of one to two rooms in a conventional house. Larger rooms can be equipped with an extra ultrasonic dog bark deterrent or equipped with one in each room. If your dog is barking around in the house, or if there are multiple dogs in the house, you need to consider using a bark stop collar.
