Nickel Shepherds Whistle Silver Nickle

A sheepdog lip whistle is a type of whistle that is held in the mouth and blown to produce high-pitched sounds that are used to train and communicate with herding dogs. The whistle is designed to be operated with the lips, hence the name "lip whistle."

Similar to other sheepdog whistles, the lip whistle produces ultrasonic or high-frequency sounds that are not audible to the human ear, but can be heard by dogs. Different frequencies of sound can be used to train different commands or behaviors, such as "come," "lie down," or "stay."

Lip whistles are popular among sheepdog handlers and trainers because they allow for greater control and precision in the production of sounds, and also because they are small and portable, making them easy to carry and use in the field.
