NoBark Ultra™ Reviews: A Humane Ultrasonic Anti Barking Device for Everyday Dog Training

NoBark Ultra is a handheld ultrasonic pet trainer sold by Wuzutech. Instead of a shock collar or spray, it plays a high-frequency tone that captures your dog's attention the moment you press the button, letting you interrupt unwanted behavior and redirect it in real time. The manufacturer describes it as a full behavior-correction tool — for barking, jumping, chewing, digging, biting, and leash pulling — that works on small, medium, and large breeds.

Key specifications (per the manufacturer)

• Ultrasonic tone in the 20–25kHz range — inaudible to humans, clear to dogs
• Three modes: Bark Control, Manual Correction, and a gentler Warning Tone
• Built-in LED assist light for night or low-light training
• USB-rechargeable battery lasting several days of normal use per charge
• Lightweight, pocket-size body — smaller than a phone, clips along on walks
• Effective on all breeds and ages (shorter bursts advised for puppies under 6 months)

1. Charge it — top up the battery with the included USB cable; one charge covers days of normal use.
2. Pick a mode — Bark Control for barking, Manual Correction for jumping or pulling, or the gentler Warning Tone.
3. Observe the behavior — wait until your dog barks, jumps, pulls, or otherwise misbehaves.
4. Press the button — the ultrasonic sound plays and captures their attention instantly.
5. Reinforce with a command — redirect, then reward calm behavior for lasting training.

Use it consistently and, per the manufacturer, your dog will begin to self-correct without you needing to raise your voice.
