How do dogs see you?

It is generally known that the dogs we love see the world in a different way. That can be observed on two fronts: their perspective in daily life and the physical nature of how their eyes work. Both are very interesting, to say the least.

Dogs place a priority on their more animalistic impulses. The needs and wants of the modern canine can easily be traced back to food. Your veterinarian can pinpoint an ailment by asking when and what you’ve been feeding your dog. Misbehavior often documented on video and social media can be linked to the desire to eat. Perspective, especially when comparing dogs and humans, is integral when breaking down the difference between the two.

The physical nature of how your dogs’ eyes work can offer perspective as well. The difference between how we see and how dogs see can be broken down into two little pieces of anatomy: rods and cones. Our retinas have more cones so we can see more colors. The dog retina has more rods, which means that their perception of greys is more prevalent, inhibiting their ability to see colors other than shades of grey. The equivalent to this is comparable to a human with red-green color blindness. Dogs also have 20/75 vision, but cannot benefit from corrective surgery, even though the thought of a dog participating in a visual acuity test is amusing. The advantages that a canine has over humans in terms of vision is increased night vision, and they can sense movement from a much longer distance.
