How your dog sees

Saturday, May 12, 2012
posted by Jim Murphy

A dog’s sense of smell is stronger than ours but what about his vision?  In low light, he can see about three times better than you can because his pupil’s are large and he has many more cones in his retina.  Cones have higher light levels. A dog’s peripheral sight is better than ours too.  His field of vision covers about 250 degrees.  Humans see sharper than dogs and we also see colors better than our best friends.  What your dog sees at 20 feet, you can see clearly from 75 feet.   Canine eyes lack one of the three sets of color receptors that are found in human eyes.  Dogs can only see blues and yellow not reds and greens.

Remember, your pets count!
