Understanding Dog Vision

The video debunks the myth that dogs see only in black and white, explaining that dogs are colorblind from a human perspective but can still perceive colors. Humans have three types of cones in their eyes for detecting blue, green, and red light, while dogs have two types, allowing them to see blue and yellow. Dogs cannot see red but can distinguish between various shades of yellow, blue, and gray. Experiments show that dogs can differentiate between different shades and colors, proving they do not see in grayscale. The video concludes with a humorous note and encourages viewer engagement.
