Disguised as a birdhouse, this patented device quickly and humanely restores peace and quiet for those vexed by a dog’s barking. When a dog barks within range of the birdhouse, it emits a harmless ultrasonic tone, inaudible to humans, that startles the animal into silence. The dog eventually associates its bark with the unpleasant sound, which conditions him to curb this undesirable behavior. An on/off switch with three sensitivity levels (15', 30', 50') lets you control the unit’s effective range, and a test mode enables you to verify the device is functioning properly. Its weatherproof ABS cabinet can be hung from a tree limb, mounted to a fence post, or hung on a wall (for best results, install less than 5' off the ground). Requires one 9-volt battery that provides power for about two months, and an LED indicates battery life. For outdoor use only. 6 1/2" H x 5 3/4" W x 5 1/4" D. (1 1/4 lbs.)
