Ultrasonic dog repeller

WEITECH WK0107 Ultrasonic Dog Chaser, Range up to 12 m

Pocket format powered by a single 9V battery for walks, runs and bike rides.

The WEITECH WK0107 Ultrasonic Dog Chaser is a handheld deterrent that keeps aggressive and stray dogs at a distance. It emits ultrasound at 20–25 kHz and over 100 dB at the device output, with a second mode adding bright warning flashes.

Ultrasound reaching up to 12 m

Aim the unit at the animal and keep a clear line of sight, since ultrasound does not pass through walls, fences or trees. A green indicator lights up while the signal is being emitted, confirming the battery still has power.

Two modes: ultrasound only or ultrasound plus flashes

Mode 1 works discreetly with no visible signal. Mode 2 adds startling light flashes for situations where a dog has already come close and a stronger response is needed.

20–25 kHz frequency, inaudible to most people

The signal irritates a dog's hearing without causing physical harm. Some younger people with sensitive hearing may faintly perceive it.

Standalone operation on a 9V 6LR61 battery

No cables or charging are required: a single 9V 6LR61 battery does the job and is not supplied. At roughly 54 g, the unit slips into a pocket or bag.
