Dogs have dichromatic vision, which means they see violet-blue, yellow and shades of grey. This is similar to a human being red-green colour blind. Dogs are typically nearsighted with a wider field of view than a human giving them better motion detection.
Called rod cells because of their shape, they function better in low light than cone cells do. Dogs also have a reflective tissue layer at the back of their eyes that helps them see in less light. This mirror-like tapetum lucidum collects and concentrates the available light to help them see when it's dark.
Human eyes have three types of cones that can identify combinations of red, blue, and green. Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.
