Humane Bark Deterrent for Calm Training Meet the NoxLumina Dog Bark Deterrent Device—a compact, humane solution that interrupts barking with a brief ultrasonic cue

There are no collars, sprays, or shocks involved, making it suitable for short training sessions with treats to reinforce calm behavior

It is designed for dogs aged about six months to eight years; avoid use with dogs that have hearing issues

Three Emitters and Dual Frequency for Reliable Coverage Three ultrasonic heads provide broader coverage than a single emitter, helping you train in rooms, yards, and on walks

You can select a fixed 25 kHz output or a variable 20–30 kHz setting to adapt to your dog’s response, reducing the chance of tuning out during sessions

Beep marks barking cues, ultrasonic output helps quiet during training, and LED aids night-time safety
