Dog Whistler Training App is a must-have application for you if you own a pet dog and want to train the dog. What the app can do is it has different buttons for different high frequency (ultrasonic) sounds that are inaudible for humans but can be heard by dogs.

You can find and accustom your dog with different high-frequency sounds for different actions by tapping buttons that start playing ultrasonic sounds. This way you can train your dog, find the dog and make him do different things anywhere without disturbing other people.

Just use ultrasonic sound to giving your dog a command. For example, you can play 2 seconds of 18 kHz sound to train the dog to sit. Similarly tap different buttons to make your dog sit, stand, run and fetch. Play a sound when you want to take the dog for a walk. Repeat it for a couple of days and your dog will react and do what you want the dog to do.

This app can be also used to scare unwanted dogs. Moreover, there are a lot of dog breeds so every dog hearing capability may differ from others.
