Ultrasonic Dog Deterrent

The Ultrasonic Dog Deterrent is an ultrasonic transmitter that emits extremely high tones that humans cannot hear, but dogs do.

Dogs find these tones extremely unpleasant and walk away. Hearing damage for the dog is not to be feared, this tool is designed not to cause any hearing damage to animals.

The device is of interest to joggers, and in particular hikers and travelers who may come across stray dogs or herding dogs.

It works 90% of the time, the remaining 10% are either hearing impaired dogs or trained dogs (like police dogs)
