Ultrasonic Dog Repellent, 3-in-1 Anti-Bark Device, Dual Channel, Up to 20m Range, Training Tool with LED Light

General Description: The ultrasonic dog repellent is a 3-in-1 anti-barking device that generates powerful ultrasonic waves. These ultrasonic waves make dogs uncomfortable, causing them to ignore people. Humans, however, cannot hear these sounds. This training tool effectively stimulates the dog's nervous system, making it easier for them to accept the owner's commands. It is also equipped with an infrared light, allowing you to track your pet as you prefer. Technical Specifications: Dimensions: 13.7 x 5.7 cm. Operation: Open the battery cover and insert one 9V battery (not included). Turn on the switch to operate the device. Can also be used as a flashlight if needed. Other Information: Repels dogs, snakes, and cats with a single click, up to 20 meters away, improving safety and protecting children from fear, while repelling animals without harming them.
