Using the latest ultrasonic technology, the Dog Chaser produces a discomforting but not harmful high frequency sound, audible to dogs but not to humans. Help stop the approach of unwanted dogs at up to 15 feet. Also a useful aid in training dogs. Requires one 9 volt battery.
The frequency emitted by ultrasonic dog repelling devices is carefully calibrated to be uncomfortable for the dog, making them run away from you. However, it is not harmful, and will not damage their hearing or produce any other consequences.
