A quieter home without a shock or prong collar: an ultrasonic device that responds to barking with a high-frequency sound dogs find unpleasant, aiming to interrupt and reduce the behaviour over time. Automatic bark detection, 15 m range: Activates on its own when barking is detected nearby, so it works without you needing to trigger it manually each time. Ultrasonic deterrent: Emits a high-frequency sound outside typical human hearing that dogs find unpleasant, interrupting the barking without physical contact. Multiple intensity levels: Adjusts to suit different dogs and situations, so you can start gentle and increase only if needed. Rechargeable, waterproof: USB rechargeable with no disposable batteries to replace, and built to handle outdoor use and weather. Specifications Type Ultrasonic anti-bark device Detection range Up to 15 metres Intensity levels Multiple, adjustable Power Rechargeable USB battery Water resistance Waterproof design Suitable for All dog breeds and sizes Results vary by dog and by what's causing the barking, so consistency and patience matter more than intensity. If barking is driven by anxiety, fear, or a medical issue, a device alone may not resolve it, and it's worth speaking with a vet or a qualified dog trainer alongside using it. Place it where it can detect barking in the room or yard your dog spends the most time.
