Trident Pet Supply Outdoor Dog Barking Control Device, Ultrasonic Dog Bark Deterrent and Training, Waterproof, No Harm To Pets, Easy Hanging;

2018 Upgraded Outdoor Dog Bark Controller by Trident Pet Supply

Does your neighbor's dog bark too much? Do you want to train your dog to stop barking?
The solution is here. Concealed as a decorative birdhouse, the Outdoor Dog Bark Controller is an ultrasonic repeller that emits an ultrasonic signal when it detects a barking dog.
An ultrasonic signal is simply a high frequency sound wave that causes no harm to the dog; the signal annoys the dog until it stops barking.
