Dogs are considered by many people to be man’s best friend and with millions of dogs owned by families in the US, it is highly likely that many dogs are in need of some amount of training. Since dogs can hear sounds at much higher frequencies (频率)than humans, there is a wonderful tool for the training of the dog. It is an app called the Dog Whistle. This isn’t your typical whistle in that it produces sounds at a frequency that is unable to be heard by humans. This unique app will allow you to train your dog without the need of a dog whistle.

The Dog Whistle free app was created by an app developer Maoli Wang specifically for dog owners who are looking for a way to communicate with their dogs in order to be able to either train them or alert them when the noise around is too great for them to hear you call them. By simply fixing the app on your iPone, it will immediately turn itself into a dog whistle.

The app includes a very powerful system that is able to create different tones ranging from 16,000 to 40,000 Hz in order for a dog to be able to hear it. The app also has an on-screen sound meter in order for the user to monitor the sound level being produced. In that way, they can decide on which frequency works best for their dog. What’s more, the app easily produces the requested tones at the frequencies necessary to be used to communicate with your dog by simply tapping the screen of your phone.

The app was designed to be used in place of a dog whistle in order to get your dog’s attention when it is too noisy around them. The sound produced through the app is at a level that only dogs are able to hear and they will respond to the sound. If you own a dog and are having behavioral issues with them, you would surely benefit from the Dog Whistle free app available by clicking here.
