✅【3-in-1 Dog Corrector】This adjustable anti bark dog device works as three tools in one: anti-bark collar, dog whistle/dog clicker, and training tool. Easy to use, animal-friendly (no discomfort!) and can quickly calm even the neighbor's barking dog.

✅【Versatile Functionality】With simple operation and powerful features, the device uses 3 ultrasonic frequencies for faster training results: fixed 25Hz, low 20-26Hz, and high 24-50Hz. For stubborn dogs, built-in buzzer and flashing lights can stop barking, digging, and excessive chewing – all without harming dogs or humans.

✅【10m Effective Range】Perfect for indoor and outdoor use, with an impressive range of 10 meters. Train your dog at home, in the park, or manage disruptive dogs quickly. For best results, maintain a clear line of sight – walls and obstacles can dampen the ultrasonic signal.

✅【Quick Charge & Long Battery Life】Use the ultrasonic dog anti barking device daily for up to 30 days on a single charge (only 1.5 hours). Compatible with Type-C, eliminating battery worries during training or walks.

✅【Compact Design】Small enough to fit in your pocket, easy to take on outdoor adventures. The stop barking dogs device features LED lighting and strobe function, providing extra safety during nighttime walks.
