Rision Birdhouse Shaped Safe and Effective Ultrasonic Dog Anti Bark Control Device Pet Barking Deterrent Device for Small, Medium and Large Dogs (Black)

When the Outdoor Bark Control is within range of constant barking, an internal microphone picks up the sound and the units is activated. The Outdoor Bark Control emits an ultrasonic sound. The ultrasonic sound can only be heard by the dog.
Started by the high-pitched sound, the dog should stop barking, as it will associate its bark with this unpleasant noise.
The ultrasonic frequency is not harmful to pets and completely inaudible to human ears.
The sensitive microphone isolates and picks up barking up to 50 feet away to solve your dog’s or your neighbor’s dog’s disturbing barking problem.

How it works :
Insert a standard 9-volt battery into the Ultrasonic Dog Bark Controller in Birdhouse Shape.
The unit is automatically activated by the sound of barking.
When the device is within the range of a barking dog, the microphone will isolate and pick up the barking to emit an ultrasonic sound to silence the dog.
The device has three range levels, including a test mode, and is effective up to 50 feet.
