Training your furry friend is an important part of being a dog parent; plus, it has many benefits, including socialization and obedience. If you're looking to incorporate a training tool, a dog whistle may be a good option for you and your pup.
But as a pet parent, you may be wondering: How does a dog whistle work? Do dog whistles hurt dogs' ears? What are the advantages of using a whistle? These are important questions to consider when looking into using a dog whistle.
How Dog Whistles Work
Whistles have been used for dog training and communication for generations. Prior to that, humans communicated with their dogs by whistling the old-fashioned way, with their breath. You can use a whistle to "talk" with your dog and establish a behavioral routine, just as you do with verbal commands or clicker training for "sit" and "stay" or playing fetch.
Dogs respond to even the quietest of whistles because they hear at a much higher frequency than humans. "Dogs and people hear about the same at low frequencies of sound (around 20Hz). This changes at high frequencies of sound, where dogs hear up to 70-100kHz, much better than people at only 20kHz," say scientists at the University of Adelaide in Australia, and dogs "hear sound frequencies at least three times as high compared to people." It may seem as if dogs react to a noise that's not there when, in reality, they're highly sensitive to something we can't hear.

You may have to try out a few different types of whistles to see which one offers you the range of sounds you (and your dog) prefer. Start by learning how to use the whistle properly (practice, practice, practice), and then play around with the sounds to figure out which tones will work for which commands.
