The SUPER DOGCHASER uses modern ultrasonic technology to repel dogs. This unit emits a high frequency sound that is in the 20,000 to 25,000Hz range. Humans can't hear this, but dogs can, and they hate it. This device also emits a super bright LED strobing light that confuses the dog and temporarily interferes with its ability to see. Stops the advance of a dog from up to 40 feet away. This device can also be used as a trainig aid and has a special setting for that. You will need one 9 volt battery to power this unit (not included). 4 3/4 inches x 1 3/4 inches x 3/4 inches

This works on most dogs but not all. I think it would be better used as some sort of training device.
I've tried this and it does work on most dogs. Some dogs however, don't seem to be affected by it unless it is very close (too close for my comfort). So I switched to your dog MACE canine Repellent instead when I go for my evening walk.
