How many meters can a dog’s eyesight see? For fixed targets, dogs can only see up to 50 meters, though for dynamic targets, dogs can capture up to 1,000 meters, and trained sheepdogs are said to be able to see people up to 1,500 meters away. For a long time, many people believed that dogs could not distinguish colors. Recently, researchers have found that dogs can distinguish different shades of gray, but also certain colors, especially blue and purple. Dogs can see farther than humans, and their vision is actually more open than humans. Dogs can see up to 250 ° -300 °, human binocular vision is only 180 °. In addition, dogs in the dark vision is also far better than humans. Because the dog eye contains a lot of cone cells and optic rod cells, especially the optic rod cells are sensitive to low light. Many times dogs bark in the dark for no reason, it is because they see where your vision can not reach.
