According to the Merck Manual, dogs have the ability to distinguish the directional origin of a noise. This is an adaptation that is useful for hunting, because dogs can hear the sound of prey attempting to flee or hide, even if they cannot see their targets. The physical part of this adaptation involves a deep ear canal, which gives dogs superior hearing when compared with humans.
Northern Virginia Community College further points out that dogs' eyesight adaptations have contributed to their success. Though dogs cannot see much in the way of color and aren't very good at distinguishing detail, they do have a superlative ability to detect movement with their eyes, a trait that is useful for hunting and guarding.
