This patented Cesar Millan in a jar device is said to be able to “quickly and humanely restore 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.

The Indoor Barking Dog Deterrent measures 3(H) x 5(W) x 2 1/2(D) inches and requires one 9-volt battery. The product is available from the Hammacher Schlemmer website for $49.95.
