Premium Automatic Ultrasonic Anti-Barking Device for Stopping Dogs From Barking Automatically

A device specially designed for dogs to address their unruly barking behavior. When the device detects a dog's barking, it automatically emits ultrasonic waves. These waves will make the dog feel astonished and uncomfortable, thereby stopping and interrupting the current barking. Once the dog stops barking, the ultrasonic waves will cease to function. After continuous use for a period of time, it will enable the dog to develop a conditioned reflex, making it understand that "barking will make it uncomfortable". This product operates automatically throughout the process and does not require manual operation. It has three settings: LOW, MED, and HIGH. There is also a TEST simulation setting. It uses a 750mAh lithium battery, which can be charged quickly via USB, and has a long standby time.
