Do dogs have the same image of the world as we do?

The eyes of dogs are positioned closer to the sides of the face than our own, and as a result, this gives them a broader field of vision than we have, but it does vary to some extent on the breed.

Broad-headed dogs such as the boxer have a better field of vision than their narrow-headed counterparts like the Afghan hound.

In general terms, dogs can see roughly three-quarters of the way around their heads, whereas our eyes only detect an image equivalent to half a circle.

We do have better overlap of vision in the central area however - so-called binocular vision - which means that we can detect a sharper image with our eyes, whereas dogs can detect moving images, often a long way away, more easily.
