1. Material: ABS
2. This product is mainly used to prevent attacks by dogs when going out.
3. The product uses a 9V salty battery. (Not shipped)
4. The energy of ultrasound is about 125dB/30cm, and strong white light of 2800mcd, which can produce strong stimulation to dogs and cats (the human ears will not hear), and it will cause uncomfortable and unbearable interference to animals, and this The harsh sound will become more serious when the animal approaches, making the dog feel unsuitable and panic and flee in panic.
The effect of repelling dogs is not good under the following conditions:
1. Your own dog, because it knows that its owner will not harm it;
2. Noisy environment, such as downtown area or roadside;
3. Dogs that are with their owners-dogged by human power; large trained dogs-well-trained;
4. When the battery voltage is too low-the transmitting power is low;
5. The above situation will not affect the use effect of this product, because their own dogs, dogs that often go shopping, dogs with their owners and well-trained dogs will not bite people randomly.
Note: It is best not to deliberately tease the dog with the dog repellent, because it is not surprising that the dog listens too much. When the light is obviously dim in the dog-driving gear, replace the battery in time.
