Dogs are not color blind. They see mostly in shades of red and blue. Their vision is not "terrible" as someone said above. They see sharply and clearly for most of their lives, then their vision starts to get worse as they age, just like it does in humans.
Compared to their sense of smell, a dog's vision is not as good, but that's because their sense of smell is so extraordinary.

Dogs see about 25% of the color we do. Is it bad? Not really. Back when they were wild (or if they are wild now) It actually helps them hunt. They aren't distracted by the colors of things, they instead focus on movement.
To a dog eyesight is not that important! That's why they can live perfectly happy blind! They use their ears & nose more than we do! They can smell things that you'll never be able to smell, the same with hearing!
