PetSafe Deluxe Outdoor Ultrasonic Bark Control - Elite No Barking Deterrent for All Dog Sizes - Up to 1/4 Acre (50 ft) Coverage - Weatherproof - Timer for Scheduled Activation - Bird House Design;

If your pooch protects his or her outdoor terrain with a chorus of excessive barking, the PetSafe Elite Outdoor Bark Control can teach dogs of all sizes to be silent. Disguised as a birdhouse, this weatherproof device has an internal microphone that picks up the sound of barking, then sends an ultrasonic tone to correct your dog€s noisy behavior. The ultrasonic tone is inaudible to most humans but is annoying to dogs. They€ll quickly learn to associate their barking with the unpleasant sound. This anti-barking deterrent can also control your neighbor€s dog€s barking if it€s within the acre hearing range. Best for smaller outdoor spaces, you add more units for additional coverage and strategically hang them in a tree or place on a solid surface outside. There€s a built-in digital timer, like an alarm clock, which can automatically turn the unit on and off at specific times. We have a €œNo Bark Guarantee€: If this product is not meeting your needs, please contact PetSafe so we can help you find a different solution for your dog. PetSafe brand is here to help you and your pet live happy together.
