Previously used dog whistles mainly for hunting dogs - The trill served as a stop signal where the dog lies down. - The double whistle as a command signal. In recent years, it has also been enforced among the mass of household dog owners. A whistle allows easy contact with the dog even over long distances and in disturbing environmental conditions (wind, leaf noise). The respective signal sounds loud and clear and is not, as is often the case with verbal commands, superimposed by the feelings of the dog handler (anger, fear, anger). The ACME dog whistles are made of plastic and frequency standardized. Each whistle is provided with an embossed number, which stands for a specific tone or frequency. The whistle signals are always clear and clear, even the trill cannot be overblown. The mouthpieces of these dog whistles are sufficiently long and equipped with a small end bead to be comfortably held in the mouth.
