Dog Whistle is a generator of high-frequency sounds for mobile phones. This is very useful for dog training processes, since the dogs can hear this type of sounds very easily.
Dog Whistle, however, also helps people who need to enter savage terrain, where animals such as wolves or jackals are a real threat. When the sounds are emitted, these animals are stunned and flee from the source of sound emission.
