A dog’s hearing is more than a few meters, and it can hear sounds within one kilometer. This is why when a dog barks, we are confused and don’t know why it is barking. This is because it hears what we cannot hear. That's why they bark. Dogs have sensitive hearing and need more care from parents.

Tip:

The reason why dogs are afraid of thunder and firecrackers is also due to their sensitive hearing. Parents should keep their dogs away from these sounds as much as possible.
