Dog whistle - adjustable frequency - training tool
Using a whistle to support training your dog to listen to various commands has been a proven strategy. Make your dog act on commands, too! Train them with one of these whistles. They produce a sound on a very high frequency, which is inaudible to humans but audible to dogs. The frequency is adjustable!
This offer contains one whistle. The high frequency sound is not audible to humans, but the whistle is not entirely silent. Some sound of air blowing through the whistle is still audible.
