The DAZER II is back! A handheld ultrasonic dog deterrent that is useful for anyone wanting to avoid contact with dogs. It provides a humane alternative to chemical sprays and physical force. The DAZER emits a high powered sound is is uncomfortable for dogs but inaudible to humans. A simple one to two second activation startles the dog (ears prick up/head on a tilt) instinctively deterring it from approaching. This device can also be used to address barking issues.
