## What is Dog Repellent?

Dog Repellent - 3D Sound with adjustable frequency, is the perfect app to chase away aggressive stray dogs. By using a special "3D Audio Technology" and an adjustable pitch, this app can repel most animals, that don't normally react to one particular sound.

It can also be used to train your dog to stop bad habits like barking or chewing on things around the house.

No need to select between presets that don't work like in other apps. And the bonus is that if your pet gets used to one high pitched sound, you can always vary it just a little bit to get them to stay away from your again.

The 3D sound technology works by creating a second wave like sound at an even higher pitched frequency which is inaudible to humans. When the sounds are combined, they create an annoying out of phase sound that can chase away animals.

Try it, you will not be dissappointed! But don't abuse it on innocent dogs!
