YOUJI Rechargeable Anti-Bark Collar – 3 Modes (Beep/Vibration/Shock), 5 Sensitivity Levels, Humane Training for All-Size Dogs

This humane anti-bark collar uses smart detection to activate only when your dog barks, eliminating false triggers. Choose from 3 training modes (beep, vibration, or adjustable shock levels 0-5) for gentle behavior correction. The rechargeable design lasts 15 days per charge (USB included) and fits dogs 8-150 lbs with adjustable reflective straps. Its progressive system starts with warnings, escalates stimuli gradually, then enters 30-second rest cycles to prevent over-correction. Ideal for safe, effective training without constant supervision.
