No, no no, it’s an Indoor Barking Dog Deterrent, not detergent. That would be silly wouldn’t it? Washing your dog silent. Anyhoo, this puppy – arf! – ultrasonics the poor mutt into an abjectly obedient and quiet beast. Which ain’t bad value if you breed turtles. [Eh? – Ed] $49.95.
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, 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 this undesirable behavior. 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.
