K9-Shield® Repeller - Powerful Ultrasonic Outdoor Dog Repellent

Scientific studies have shown that properly tuned ultrasound effectively repels dogs.

Ultrasound acts as a deterrent signal for dogs; it is unpleasant for them but does not cause any real harm.

Our devices are designed to emit ultrasonic frequencies within the hearing range of the targeted pests. While these sounds are generally inaudible to adults, some individuals—especially younger people or those with sensitive hearing—may perceive a brief high-pitched sound when the device is activated.

That said, the device only triggers after a short detection delay via its infrared sensor, and the emission lasts only a few seconds. If you are indoors or not directly facing the device, you are unlikely to notice anything. Even outdoors, most people report little to no disturbance unless they stand directly in front of the device when it activates. Overall, it is designed to minimize any discomfort for humans while remaining effective against animals.

The repellent is adapted to target dogs but may also repel certain animals sensitive to the same frequencies, such as foxes.

If you have any issues with your device, please contact our customer service team. We guarantee a response within 24 hours and offer a 30-day money-back guarantee.

Simply plant the device in the ground. Its PIR sensor detects the presence of dogs and automatically activates the emission of ultrasound to repel them.
