How Well Do Dogs See in the Dark?

09 September 2013 ~ 2 Comments

Well, while dogs don’t see as good as cats in dim light, they still see a lot better than we do. In fact, dogs see about 5 times better than humans. Dogs have such a good night vision because they have larger pupils which allow more light to get through, and also, a dog’s retina has more rod cells (these are photoreceptor cells that can function in dim light).

Dogs’ improved night vision is also due to the tapetum. The tapetum lies behind the retina, and is a mirror-like layer of tissue that reflects light back through the retina, giving it an extra chance to register light. The tapetum is what makes animals eyes glow in low light, too, as you can see in this photo of me and Toby:

The picture below was photoshopped to give you a chance tho see what dogs might see like in the dark. Pretty cool!

    Great – My older Corgi (11 years old) has cataract problems. I’ve ruled out diabetes and other heath problems. This article was helpful, but I wonder how much he can see in the dark??
