The ultrasonic sound emitted by DOG OFF gets the dogs attention and distracts them from their current activity sufficiently for them to receive your command.
Works well with disciplined larger breeds of dog. Smaller 'smart arsed' dogs, particularly poodle crosses need some persavearance.
* The unit has been designed to release an ultrasonic wave that will transmit up to 20feet.
* The ultrasonic sounded emitted is not harmful to the dog and is not audible to the human ear
