I need this. Not too much for my dog, French Bulldogs barely bark. But for that frikken dog from downstairs. These people downstairs moved in 2 month ago beneath us and their dog barks NONSTOP! They always leave the balcony door open so it’s bark echoes all over the place. I will get this anti bark device and will have it dangle right in front of their window from a string (only on sunny days since this device is only for indoor use)
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. One 9-volt battery (not included) provides power for about two months, and an LED indicates battery life.
