Ultrasonic Barking Device Anti-Dog Barking USB Charging Driver LED Light Portable Dog Training

This product is mainly used to prevent being attacked by dogs when going out. The product uses a 9V salty battery. The ultrasonic energy is about 125dB/30cm, and a strong white light of 2800mcd can produce strong stimulation to dogs and cats (the human ears cannot hear it). It will cause uncomfortable and unbearable interference to animals. Moreover, this harsh sound will become more serious when the animal approaches, making the dog feel unsuitable and flee in panic. Dog removal is not effective in the following situations: 1. Keep a dog yourself because it knows that its owner will not hurt it. 2. Noisy environments, such as downtown areas or on the roadside. 3. The dog with the owner - the dog relies on the power of the human being. the trained large dog - is well-trained. 2. When the battery voltage is too low - the transmission power is low. The above situation will not affect the effectiveness of this product, because your own dog, your dog who often goes shopping, your dog with your owner, or your well-trained dog will not bite people randomly. Note: It is best not to use a dog-repellent to tease the dog on purpose, because it is not surprising that the dog will hear too much.
