The Indoor Barking Dog Deterrent.

"This patented device quickly and humanely restores peace and quiet to a home vexed by a dog's excessive barking. No special collar is required; when a dog barks within 25' of the unit in an open space, it emits a harmless ultrasonic tone (inaudible to humans) that startles the animal into silence. The dog quickly associates its bark with the unpleasant sound, which conditions him to curb barking. The unit can also be activated manually to help you correct a dog's other bad habits, such as lying on furniture or foraging through the trash. Requires one 9-volt battery that provides power for two months; an LED indicates battery life. For indoor use only. 3"" H x 5"" W x 2 1/2"" D. (8 oz.)"
