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. Perfect solution for peace and quiet from loud pets. Designed for easy hanging/ mounting on a tree, wall or fence post to keep your own dog or your neighbors' dog from barking. Safe and effective for most sizes and breeds of dogs.
