Dog vision

How dogs see, which is less sharp than people, with a limited range of colors, but better in low light and at spotting movement.

Also called: canine vision, how dogs see, dog color vision, dog eyesight

Dogs see the world differently from people. They have two types of color-sensing cells, not three, so they see mostly blues and yellows and cannot easily tell red from green. Their sharpness is lower than ours, commonly estimated at about 20/75 on a human chart, so details look softer from a distance.

They make up for this in other ways. Dogs see better in dim light, thanks to a reflective layer behind the retina, and they are good at noticing small movements. Their wide field of view is larger than ours, though it varies by head shape: long-nosed breeds see a wider area than flat-faced ones.

Dogs rely more on smell and sound than on sight. If a dog suddenly seems to bump into things, or its eyes look cloudy or red, ask a veterinarian.
