【Effective Ultrasonic Bark Control Device for Most Breeds】This device is suitable for most breeds and sizes of dogs, except for deaf or hard-of-hearing dogs. Some dogs may be afraid of or dislike the ultrasound and therefore continue to bark at first. Please allow up to two weeks of training. Safe and Effective Ultrasonic Bark Control Device: Ultrasound is harmless to animals. If the dog is hard of hearing or aggressive, the device may be ineffective. It is not recommended to use an ultrasonic bark control device on two or more dogs that bark simultaneously.【Easy and Weatherproof Installation】This device is designed to be easily hung or attached to trees, walls, or fence posts to prevent your or your neighbor's dog from barking. Ensure the ultrasonic bark control device is placed in an open area, facing the dog. Product Description: This product is designed in the style of an alarm clock. This deluxe ultrasonic anti-barking device for outdoor use can be hung from a tree or placed anywhere in your home. Suitable for the garden, it can be hung or placed on a table or any other flat surface. When it detects excessive barking, its microphone picks up the sound and activates the device. The device then emits a high-frequency ultrasonic wave, inaudible to dogs but not to humans. Stimulated by this sound, the dog stops barking. Because the ultrasound is unpleasant for the dog, it eventually stops barking. Designed for outdoor use, this ultrasonic device is robust and waterproof. It has three sensitivity levels (ranges of 4.5 m, 9 m, and 15.24 m respectively) and a test mode. An indicator light shows when it is operating. Outdoors, it can be deactivated to conserve battery power.
