Petsage Outdoor Ultrasonic Bark Control Birdhouse
Discourage your loudmouth dog from disrupting the neighborhood with constant barking. The Radio Systems Outdoor Bark Control device emits a safe, high-pitched sound (inaudible to most humans) that will deter noisy dogs from barking. The unit is modeled to look like a birdhouse that can hang in a tree, on a fence post or anywhere outside. The ultrasonic bark controller is battery-operated and has three settings plus a test option.
