Using the very latest, and unique ultrasonic technology, the Electronic DOG CHASER uses two different ways to humanely repel a dog.
One is the discomforting and annoying, but not harmful, high frequency sound (20,000Hz-25,000Hz), audible only to dogs but not to humans. They will "hate" this sound, and it will make them get away from the user…fast!
The second is a super bright LED flashing strobe that temporarily blinds and confuses the dog…they find it so annoying that they will also turn and run away. These two methods combined, will help stop the approach of any unwanted dogs up to 40 feet away.
This handy unit also has a training setting, which can help some pet owners train the family canine. Only requires one 9 volt battery, which is not included. Can also be used as a flashlight, which is helpful before sunrise, and after sunset, or even in a dark garage or basement.
