Dog Repellent Sound - Prank

Dog Repellent sound is an app that emits ultrasonic distressing in animals and acts as a bark repellent / anti dogs app.
The samples in this app range from 1000MHz to 15000Mhz which is close to the limit of the human ear and also close to the limit of most mobile devices. Dogs can hear frequencies up to 50khz!

Turn your phone up, and launch Dog Repellent Sound get within 20 meters of your dog and try some different frequencies.

Unfortunately Dog Repellent Sound prank may not work with some puppy as there are many variables. The developer makes no guarantees. This app should only be used as a means to change bad behaviour and not to tease.

The frequency of emitted sound can be annoying to humans but is not harmful.

Includes volume control, use high volume to increase effects.

Important Note: Not all frequencies may work with your phone/tablet. Some devices may render artifacts at some high pitched frequencies due to the phone software/manufacturer and/or the device's build in speakers. A safe way to go is around 15000 kHz because most devices can render that and is high pitched enough for dogs. A Nexus 7 for example may start to choke beyond 16000 kHz, while a ZTE phone may go up to 18000 kHz. If you can't hear the signal it doesn't mean it doesn't work because signals above 16000 kHz are usually beyond human hearing. Check and see what works best for you.

Warning : This app is not sure to work ! it's simply a prank !
