Dog Whistle

Dogs can hear sounds of high frequency which are hardly perceived by human ears. By simply adjusting sound frequency you can make the dog react your way. Dog Whistle is like a silent helper in training your puppies without disturbing people.
You can also use Dog Whistle to train your dogs, as well as pull a prank on animals
Features:

How to use:

1) Run the dog whistle app and listen. You will hear a disturbing sound. What you are hearing is only a secondary sound made by the air forced through the metal tubing; the actual whistle is inaudible to your ears.

2) Adjust the whistle to your own dog. Even dogs can't hear all frequencies. Wait until he is asleep and gently blow on the dog whistle. Continue testing until your dog perks up. You will then know you have reached a frequency he can hear.

3) Use the dog whistle with varying sequences to train your dog. For example, one long burst can mean "come," while a series of short, staccato bursts might mean "sit." Keep your whistle commands consistent and your dog will always know what you expect of him.

4) Choose from a variety of sound types (This Dog whistler application contains several frequency: 7kHz, 10kHz, 15kHz, 19kHz.)
