Dogs have highly sensitive hearing and can detect sounds high above human capabilities. Their ears are mobile due to 18 muscles that turn, lift, and tilt them to pinpoint where the sound is coming from. Because of their acute sense of hearing, dogs can hear sounds from four times the distance a human can.
