If you're tired of constant barking disturbing your peace, or dealing with complaints from neighbors about your dog's noise, our ultrasonic anti barking device is the perfect humane solution for your home and yard. Designed with pet safety and effective training in mind, this battery operated bark silencer helps reduce excessive barking without any shocks, pain, or fear. Featuring a 50foot long range and dual ultrasonic emitters, this bark deterrent delivers stable correction across your entire yard, patio, or garden. The 120° wide coverage eliminates dead zones, making it ideal for controlling barking from multiple dogs or even your neighbor's dog. With 3 adjustable ultrasonic frequencies and 4 sensitivity levels, you can customize the correction intensity to work for small, medium, and large dogs aged 6 months to 8 years old. Built with IPX5 waterproof technology, this outdoor bark control device withstands rain, snow, and harsh weather conditions, so you can leave it hanging on your fence, tree, or wall year-round without worry. The natural wood-grain finish blends seamlessly with any outdoor decor, keeping your yard looking clean and natural. Unlike rechargeable models that require constant power outlets, this anti barking device runs on 9-volt battery (not included), offering true wireless convenience for remote or off-grid areas. One set of batteries provides months of regular use, and the low-battery indicator ensures you never run out of power unexpectedly. The smart noise filter technology prevents false triggers from TV, talking, traffic, or wind, so the device only activates when real dog barking is detected. This means no interruptions to your daily life, and no unnecessary ultrasonic emissions.
