Dog Bark Control & Training: This anti-bark device utilizes the latest technology suitable for dogs of all breeds and sizes. It effectively stops excessive and noisy barking by emitting a sound that silences your dog. Once the barking stops, the device automatically stops emitting waves.

3 Modes: Our anti-barking device features three adjustable volume levels - low, medium, and high, with frequency bands ranging from 15KHZ-30KHZ for large dogs; 20KHZ for docile dogs and 30KHZ for small dogs. We recommend this device for dogs aged between 6 months and 8 years old.

Safe for Dogs & Humans: It won't cause interference or harm to humans since humans cannot hear these frequency bands. However, dogs will be sensitive to them. Please allow up to 2 weeks for training.

Design & Waterproof: This device is designed for easy hanging or mounting on a tree, wall, or fence post to prevent your own or your neighbor's dog from barking. The shell has an IP4 waterproof grade and can effectively resist external splash. However, if it rains, it's best to take it back indoors to protect the equipment and extend its life.
