【Pet-Friendly Anti-Barking Device】This ultrasonic bark control device works by emitting a stable frequency sound that only dogs can hear, allowing dogs to avoid the annoying voice that triggers barking. The anti-barking device is harmless to both people's and dogs' hearing, perfect for creating a quiet room for dog lovers and stopping unwanted behaviors such as barking, digging, fighting, etc.

【Effective on Dogs of All Sizes】The ultrasonic dog bark deterrent with 3 adjustable sensitivity and frequency levels (15-30 kHz for large, aggressive dogs; 20 kHz for docile dogs; 30 kHz for small dogs) easily addresses different types of barking dogs. Adjusting the frequency weekly can maintain the training effect. The wide 33 ft (10 m) control range is suitable for preventing your neighbor's dog from barking at you and your family. 【Easy to Use】 This rechargeable dog bark control device with a light indicator can be used effortlessly. The light will flash blue when in operation; red when the sonic bark control device is triggered by barking; the red light will flash when the device is low on power. The 3.7V 1500mAh USB rechargeable battery can be used for 30 days, saving you the hassle and cost of batteries. 【Indoor and Outdoor Use】 The humane bark control devices, with their IP4 rainproof rating and portable hook, are suitable for outdoor use and can be easily hung on trees, walls, or fence posts. But if it rains heavily, it's best to take it back inside to help protect the equipment and prolong its lifespan. Small ultrasonic dog training devices can be set up more than 1.5 meters indoors, which can make them more effective. 【Perfect Service】 Our dog bark box comes with 1 charging cable, 1 dog training whistle, and 2 screws for easy installation.
