This lightweight, compact, ‘silent’ whistle is ideal for dog training, both indoors and out. The High Frequency Whistle is particularly appropriate for noise-sensitive breeds such as Border Collies.
It should be noted that this whistle is just audible to the human ear, essential for gauging its efficiency.
