The following situations are not good for dogs:

1. Own a dog because it knows that its owner will not harm it;

2. Noisy environment, such as downtown or roadside;

The dog with the host;
A large trained dog;

2. Low emission power when the battery voltage is too low.

This will not affect the use of the product, because the dog, the dog that goes shopping, the dog with the owner, and the trained dog will not bite.

Note: it is usually best not to play dog with a dog, because it is not surprising that dogs listen more.
Replace the battery in time when the dog's light is clearly dimmed.

The effect is better when using alkaline battery.
The ultrasonic output power and efficiency of this product have been the best in the same kind of products.
Due to the current power limit of the ultrasonic head, if the output power is further provided, the ultrasonic head will be damaged rapidly.
In the future, there will be a high power ultrasonic head development (no higher ultrasonic emission head at present), it is expected to be improved, hope to understand!
