50 Ft Range Ultrasonic No Bark Training Humane Barking Deterrent Device with 2X Ultrasonic Emitters,Black

The ultrasonic dog barking deterrent device is a fast,safe, and efficient training system that uses high-power audio signals to attract the dog's attention, then guides and corrects its behavior through the owner's gestures. Our dog bark deterrent device features dual ultrasonic frequencies (fixed 25kHz and variable 20-30kHz), combining 4 ultrasonic modes plus an audible beep and LED flashlight for versatile training. With cutting-edge technology and an effective 50ft range, this device is designed to help you regain peace and tranquility in your home.While only 10% of dogs become immune to our advanced 25kHz dog barking control devices, we refuse to settle for less than 100% effectiveness. That's why we added an undulating 20 to 30 KHz 8-second ultrasonic boom - 100% painless and 100% effective. It provides 300% faster dog training compared to a dog whistle, dog clicker, bark box, bark collar, air horn, or in-person dog training program. This magic solution for behavior modification eliminates the need for E-Collars that might impact your dog's health. It effectively puts an end to barking, chewing, biting, jumping, and other annoying behaviors without harming your dog's well-being. It also helps repel aggressive street dogs to safeguard yourself or stop dog fights to protect your pet.
