Fun Fact: Vision of a Dog

Yorkshire Terriers, Cavachons, Yorkichons and Yorkie Mixes, like all dogs, have a different view of the world than humans do.

 Many of us think that our dogs are colorblind but in fact they are not.  They do not see as many colors as we do but they can differentiate colors within the range of sepia hues.

Although dogs cannot see as many colors as humans can, they have different benefits to their vision than we do.

Dogs have a broader field of vision and can detect movement better than humans can.  Our field of vision has a range of about 160 degrees while our dogs have a field of vision from about 200 to 270 degrees.  This fluctuation depends on the size of a dog’s snout. 

Because of the broader field of vision and a special membrane that covers their eyes they can detect movement from a much larger area than we can and they have much better night vision than we do which is why many dogs are used for hunting and like to do a little bit of hunting of their own in the back yard.

Even when a dog begins to lose their vision they are still capable of leading a full life because of the fact that their sense of hearing and smell is also so excellent.
