A dog raised by oneself, because it knows its owner won't harm it; 2. Environments with high noise levels, such as busy urban areas or by the roadside; 3. A dog with its owner - the dog is very powerful. A trained large dog - well-trained; 2. When the battery voltage is too low - the transmission power is low. The above situation will not affect the usage effect of this product, because one's own dog, a dog that often goes shopping, a dog that is with its owner, and a well-trained dog will not bite people randomly. Note: It's best not to use a dog repellent to deliberately tease dogs in daily life, as it won't be surprising if dogs hear about it too often. When the lights in the dog repellent gear are obviously dim, charge it in time Directions 3+
