What does your Westie see

Dogs appear to be better than people with peripheral vision, but their close-up vision does not seem as sharp as a human's. The dog's lateral eye placement allows better wide angle vision but hinders depth perception and close up viewing because there is minimal visual overlap between the two eyes.

Abundant light sensitive cells called rods in your dog's retina help it detect motion and see well in dim light. Clear advantages for canines stalking prey at dusk or dawn or guarding territory against intruders. The human retina is made up predominantly of cones receptors that are better at detecting colour and processing bright light.

Contrary to belief, dogs are not completely colour blind for they do have cones in their retinas.

But dogs can't distinguish the full spectrum of colours.
