DNBeffulgent Ultrasonic Dog Bark Deterrent orange 32 ft 25kHz 2026kHz 2450kHz 480mAh USB-C

Ultrasonic Dog Bark Deterrent

The DNBeffulgent ultrasonic deterrent is a portable training aid designed to stop unwanted barking, biting, and jumping. It emits high-frequency sound at fixed 25kHz, variable 2026kHz, or variable 2450kHz settings, plus an audible beep and bright LED flashlight. Effective up to 32 ft with a clear line of sight, it suits adults seeking a humane, shock-free way to manage their own dog or a neighbour's dog outdoors or indoors.

Replaces spray collars and noise makers

This device replaces citronella collars, shock collars, and handheld noisemakers by using sound alone to interrupt behaviour. The jump is worth it when you need a single tool that works on 97% of dogs aged six months to eight years without contact or pain. It is not for owners of dogs with epilepsy or hearing impairment, nor for situations where a solid barrier blocks the ultrasonic path.

Simple one-button operation

Point the unit at the dog and press the button to activate the selected mode; a built-in safety lock prevents accidental discharge around children. The 480mAh lithium-ion battery charges fully in 1.5 hours via USB-C and delivers up to 180 days of standby time. What usually goes wrong is aiming off-axis or expecting results through walls, which the ultrasonic beam cannot penetrate.
