Mini Ultrasonic Dog Deterrent K26, 20-30kHz Sweep Frequency, Strobe Light, 300mAh, Type-C, 4 Colors

Product Name: Mini Ultrasonic Dog Deterrent Model No.: K26 Purpose: Safe & efficient dog deterrence for outdoor activities, delivery work, yard protection, and pet training aid. How It Works This dog deterrent uses a combination of ultrasonic waves and visual interference to trigger dogs' natural avoidance instincts. It is a reflex-based protective tool that is both safe and effective. Ultrasonic Principle: Dogs hear 40Hz–60kHz (humans: 20Hz–20kHz). This device emits 20kHz–30kHz ultrasonic waves that cause discomfort or alertness, encouraging dogs to move away. Sweep Frequency Anti-Adaptation: The frequency automatically changes (e.g., 1–2 times per second) to prevent dogs from getting used to a single frequency. Dual Ultrasonic Heads: Directional ultrasonic beams ensure focused energy and longer range (effective coverage: 5–10 meters). High-Frequency Strobe Light: Built-in LED flashes synchronously with ultrasonic emission (e.g., 3–5 times per second), using dogs' sensitivity to fast-moving light (especially at night) to enhance deterrence.

Avoid pointing the ultrasonic emitter directly at human eyes or pet eyes. Clean the ultrasonic emission holes regularly to ensure no blockage. Some dogs (e.g., hearing-impaired or puppies) may show weaker response. Combine with other protective measures if needed. Children should use this device under adult supervision.
