Our Electronic Dog Repellents stop the approach of unwanted dogs up to 40 feet! The Sonic Dog Repellent repels a dog by using a discomforting, high frequency sound (20,000Hz-25,000Hz), audible to dogs but not to humans, and a super bright LED flashing strobe that temporarily blinds and confuses the dog. This nifty electronic dog deterrant can also be used as a flashlight, making it doubly useful. Requires on 9 volt battery.
