1. 3-IN-1 DOG BARK DETERRENT: This innovative anti-barking device includes a built-in flashlight function. The ultrasonic bark control effectively captures your dog's attention, helping to curb unwanted behaviors such as barking, digging, scratching, biting, or jumping on furniture. For optimal results, use consistently for at least one week. 2. DESIGNED FOR ALL DOG SIZES: The Ultrasonic Bark Control emits sounds within the dog’s hearing range of 24kHz to 26kHz. This frequency is inaudible to humans, ensuring that the device captures your dog's attention safely without disturbing people nearby. 3. USER-FRIENDLY AND SAFE: Featuring a comfortable wrist strap, this anti-barking device is easy to hold and carry. A simple one-button operation turns it on and off, while another button allows you to switch between a standard flashlight and a flashing ultrasonic deterrent. It operates safely on dogs and requires one 9V carbon battery (not included). 4. EFFECTIVE DUAL ULTRASONIC SPEAKERS: The Dog Training and Bark Control Unit features dual speakers that can project ultrasonic sounds up to 32 feet, making it effective for deterring aggressive dogs. Its portable design is suitable for both indoor and outdoor use, allowing you to train your dog or repel other dogs when you're out and about. The combination of ultrasonic waves and a high-frequency flashlight enhances its effectiveness, especially in low-light conditions. 5. MULTI-FUNCTION LED FLASHLIGHT: Beyond barking control, this device includes a powerful LED flashlight that can help deter approaching dogs. By holding down the button, you can emit both ultrasonic sounds and a bright LED flash. The flashlight can also be used independently to illuminate your path. This product provides a practical solution for dog owners seeking a safe and effective way to manage barking and ensure a peaceful environment.
