Outdoor Ultrasonic Bark Control Device - 50-foot Range Anti Barking Device with Adjustable Ultrasonic Level Control - Ideal for Backyards | 2022 Birdhouse Design Review

☁Safe for Dogs & People☁ Ultrasounds will not cause interference or harm to humans because humans cannot hear these frequency bands, but dogs are sensitive to these ultrasounds. Different dogs may be sensitive to different frequency bands of ultrasound. Some dogs may be afraid or dislike the sound and won't stop barking at first, so turn the knob to test different frequency bands for best results. ☁Great Rang 50ft☁ The ultrasonic penetration range is 50ft, covering indoor and outdoor areas. Compared to traditional dog trainers, it completely frees your hands. You can easily train your dog's behavior by turning on the knob. Tested for best results within 50 feet. The smaller the range, the better the effect. If you or your neighbor's dog barks too excitedly, put it in the right spot and you'll have a quiet resting environment. ☁2022 New Version☁ This bark control is built with high quality materials to ensure long-term use; this version is lightweight and super cute in design, suitable for outdoor decoration; it also has fixtures installed inside to resist falling. ☁Durable Power Supply and Waterproof☁ The new bark controller is equipped with a powerful battery, which can work continuously for 30 days on a full charge. Designed to hang/install easily on trees, walls or fence posts to stop any dog barking (within range), indoors, outdoors, anywhere. Protect your warmth and peace. ☁Using Friendly Tips☁ Dog Deterrent is not suitable for the following: aggressive dogs, noisy environments, hearing impaired dogs, multiple dogs together, dogs under 6 months or over 8 years old.
