Mini ultrasonic deterrent for dogs

The DNBeffulgent Mini Ultrasonic Bark Deterrent emits a 40KHz tone to interrupt unwanted barking, digging or chasing. It is designed for owners who want a handheld, pain-free way to manage their own dog or a neighbour's pet during walks or at home.

Rechargeable battery with USB charging

A built-in lithium-ion cell reaches full charge in 30 minutes from any standard USB source such as a power bank, laptop or car charger. The pack includes the device and a charging cable so no separate batteries are required.

21-foot range and single-frequency output

The ultrasonic beam is effective up to 21 feet and uses a fixed 40KHz frequency suited to small, medium and large breeds. It cannot penetrate walls or solid obstacles, so line-of-sight positioning is necessary for the sound to reach the animal.

Questions about this item

How often will the built-in lithium-ion cell need recharging?

The device fully charges in 30 minutes via any standard USB port and then runs until the 1 Wh cell is depleted; recharge whenever the indicator shows low power.

What stops the unit from working at distances beyond 21 feet?

The ultrasonic output is calibrated for a 21-foot effective range; beyond that distance the 40 KHz signal drops below the level that reliably interrupts barking.

Does the housing get warm or make noise during extended training sessions?

The emitter is silent to human ears and the low-power 1 Wh battery produces no noticeable heat even when the button is pressed repeatedly throughout the day.
