Electronic Ultrasonic Dog Repeller

This Electronic Dog Repeller uses a couple of ways to repel dogs. One is the discomforting but not harmful high frequency sound (20,000Hz - 25,000Hz), audible to dogs but not to humans. And, the second is a super bright LED flashing strobe that temporarily blinds and confuses the dog. Helps stop the approach of unwanted dogs up to 40 feet.

Also features a training setting to help you correct your dog's behavior and can also be used as a flashlight.

Dimensions: 4 3/4" x 1 3/4" x 3/4"
