Ultrasonic Bark Control for Dogs

The Kole Imports OS923 is a wireless training aid that detects barking and emits an ultrasonic sound to discourage the behaviour. It is designed for owners who want a hands-off way to reduce excessive noise from dogs of any breed. The white plastic unit measures 1.875 by 1.25 by 5 inches and weighs .4375 lbs.

Sustained Operation and Range

The device monitors continuously and reacts each time a bark is detected within its 20 foot range. An LED indicator confirms the unit is active, while low and high volume settings let you adjust the output level for the environment. A single 9V battery powers the unit, though batteries are not included in the package.

Replaces Shout-Based Corrections

This stopper replaces the need for constant verbal commands or physical intervention when a dog barks persistently. The jump is worth it when you want consistent, automated feedback that works even when you are in another room. It is not suited for situations where the dog is regularly farther than 20 feet from the unit.

Questions about this item

Does the ultrasonic bark stopper make any audible noise or generate heat during continuous use?

The device emits ultrasonic sounds beyond human hearing and has no moving parts, so it runs silently and produces no noticeable heat.

What must I already own for the OS923 to operate out of the box?

You need one 9 V battery, which is not included, and a wall or surface for the built-in mount holes if you want it fixed in place.

Will the 20-foot range still cover my older dog's bed if the unit is mounted across the room?

Yes, the 20-foot detection radius works regardless of the dog's age, so an older dog resting within that distance will still trigger the ultrasonic correction.
