1. DOG BARK CONTROL AND PET TRAINER Our Ultrasonic Dog Bark Deterrent provides effective bark control and helps reduce unwanted behaviors such as digging, fighting, chewing furniture, and eating unsafe foods. It offers three modes Chaser, Train, and Light. Use the knob to switch among the modes to obtain the best results. 2. POWERFUL DUAL ULTRASONIC SPEAKERS The device uses two speakers with a reach of up to 33 feet to deter unfriendly dogs. Its portable design makes it suitable for indoor or outdoor use. You can employ the ultrasonic bark deterrent to train your dog or carry it along to deter other dogs. High frequency flashlights combined with ultrasound increase deterrence, especially at night or in low light environments. 3. LED FLASHLIGHT WITH MULTI SETTINGS In addition to training and bark control, a super bright flashlight is included as a secondary way to stop an approaching dog. Holding down the button emits an ultrasonic sound and triggers rapid LED flashlight flashes to help correct a dog's behavior. The flashlight can also be turned on to light your way home. 4. SAFE FOR DOGS AND HUMANS This is a humane and widely used method to prevent barking from your dog or a neighbor’s dog. The ultrasound is inaudible to humans and therefore does not cause interference or harm, while dogs are sensitive to these ultrasound frequencies. Use scenarios - At home in the yard or doorway: switch to Train or Chaser mode during training sessions to reduce barking and reinforce calm behavior without physical contact. - On walks or in parks: carry the device to deter aggressive or overly vocal dogs within a safe range, using the Room or Light mode as needed for visibility at night. - Indoors during quiet hours or late-night activities: use the UltraSonic and LED light together to deter barking and provide illumination if you need to move around the home.
