Dogs react primarily to sounds and coustic signals, and not to language.

Therefore the whistle is optimal for training and hunting as the sound can hardly be heard. Its sound is clearly different from the ususal sounds that surround your dog every day.

Please note that a light whistle is completely sufficient, as sounds that are too loud rather frighten your dog.

Dogs have a much wider spectrum of sounds they can hear and perceive the tones of the high frequency whistle at the same volume as the sounds of a normal dog whistle.

The pitch of the high frequency whistle is individually adjustable. The higher tones are intended to be used at close range and the lower tones for distances that are further away.
