Some breeds, particularly the [[sighthound]]s, have a field of vision up to 270° (compared to 180° for humans), although broad-headed breeds with short noses have a much narrower field of vision, as low as 180°.<ref name="note1" /><ref name="note2" />

 

Dogs detect sounds as low as the 16 to 20 [[Hertz|Hz]] frequency range (compared to 20 to 70 Hz for humans) and above 45 kHz<ref>[http://www.lsu.edu/deafness/HearingRange.html How well do dogs and other animals hear]</ref> (compared to 13 to 20 kHz for humans),<ref name="note2" /> and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate and raise or lower a dog's ear. Additionally, a dog can identify a sound's location much faster than a human can, as well as hear sounds up to four times the distance that humans are able to. Those with more natural ear shapes, like those of wild canids like the fox, generally hear better than those with the floppier ears of many domesticated species.
