It is often said that the dogs sense of sight is less developed than the other senses, but how do dogs see? Let’s try to answer the most requested questions from our readers, i.e. if the dogs see colors and if the dogs see in the dark. Some of our followers have even asked us if the dogs see the ghosts, but better not to dwell on this last question, it may scare some of you so focus on all aspects of the dog’s sight.
Do dogs see colors?
The dog’s sight is not as poorly developed as many of you think, but it differs from ours in many respects. In dog eyes the sticks are larger than the cones, much more so than in human eyes. The sticks allow black and white vision in lighter (twilight) light conditions while the cones are used for the colors that dogs can see. In any case, colors are not very important to them. This does not mean that dogs do not see colors , the dog sees some color shades, although it does not have the ability to see the details and has less depth perception than human beings.
What colors do dogs see?
Dogs distinguish colors like green and red with great difficulty, with the tendency to perceive them as yellow tones. Dogs see blue, yellow and purple colors much more distinctly than others.
Do dogs see in the dark? How do dogs see at night
Thanks to the sticks, dogs can see in the dark and have an excellent view from afar, and can see movement very well but are less able to make out details. However, they can easily recognize their master from several hundred meters away. They also succeed in distinguishing gestures from afar, a really useful skill during training. In fact, dogs are able to communicate at a distance not only with us but also with their own kind.
How do dogs see?
The field of view of the dog is about 240 ° with a binocular vision and monocular vision of 80 ° each. These features, among other things, allow our friend to see us when we walk by his side during the walks. Note that when a dog’s eyes are more frontal (as in the case of the Pekinese and Bulldog), the binocular vision will be greater, but at the expense of their field of vision. Conversely, when the dog’s eyes are laterally placed (as in the case of the German Shepherd) the binocular vision will be reduced with consequent advantage with their general field of vision.
