Description

How the Product Works:The average human hearing frequency ranges from 20HZ ~ 20KHZ, while dogs can hear from 15HZ ~ 120KHZ. The anti-barking device produces a high-pitched ultrasonic sound that attracts the attention of dogs and prevents bad behaviors. It is safe for dogs of any size, you and your loved ones. Working Mode:When the dog barks within the control range of the device, the internal microphone of the device picks up thesound and automatically activates the ultrasonic wave. The dog stops barking after hearing that, which makes the wave stop being emitted. Remember to give your pet the appropriate reward when it stops barking so that it relates the ultrasonic frequency with your desire to have it stop barking.  How to Test:1.
