How good is a dog’s hearing ability?

Dogs have a great sense of hearing. In fact, it is their second most developed sense (next to smell). Dogs can hear much sharper than humans. Not only can they detect sounds that are much too faint for humans, but they also can hear sounds pitched at frequencies above or below a human’s range. Dogs can hear in the range of 67 HZ to 45 kHZ (compared to a high range of 20 kHZ in humans).
