Humane Ultrasonic Bark Deterrent

The DNBeffulgent SD-02GN uses three ultrasonic emitters to discourage excessive barking without causing harm. It is designed for dog owners seeking a non-invasive training aid for indoor use. The device arrives new and includes a built-in lithium-polymer battery rated at 5 watt-hours. No separate battery purchase is required.

Suits Indoor Training.

This deterrent suits adults aged 18 years and older who want a simple, humane way to reduce nuisance barking inside the home. Buyers who need weather-resistant operation for gardens or yards should look elsewhere. The single-unit pack also limits coverage for households with several dogs in different rooms.

Simple Placement with Battery Care

Installation consists of placing the light-green unit in the problem area; no wiring or mounting hardware is involved. The internal battery is not user-replaceable, so the whole device must be recharged when depleted. The main issue owners report is forgetting to recharge, which leaves the dog unmonitored until the unit powers up again.

Questions about this item

Does the DNBeffulgent SD-02GN ultrasonic bark deterrent need a separate power supply to operate?

No, it includes a built-in lithium-polymer battery rated at 5 watt-hours so the unit runs without an external adapter.

Will the SD-02GN affect other pets such as cats or small animals that share the same indoor space?

The device targets dogs with three ultrasonic emitters; other animals may hear the tone but the product is designed for canine training.

How can I confirm the SD-02GN is emitting ultrasound after I switch it on?

The indicator light shows the unit is active; since the frequency is above human hearing you cannot hear it, but the light verifies operation.
