This dog is the greatest example of optimism and determination. Dog vision is very different from human one. First of all, because dogs’ eyes are set on the sides of their heads, dogs have a larger visual field. Most dogs have a total visual field of 250 degrees, while human’s total visual field is only 190 degrees, because our eyes are set directly on the front of the face. Also dogs see better than we do in dim light. Although dogs have greater peripheral vision, they cannot see details as well as humans. And very often objects that are stationary don’t catch dogs’ attention, they might not even notice them, not the case for the dog from this video, though. When undecided about what they are seeing, dogs depend on their sense of smell to confirm any doubts. Although motionless objects can be missed by dogs’ attention, their sight is very sensitive to moving objects. Dogs can perceive direction, speed and may even be able to recognize an animal or human by their pattern of movement.
