My dogs do the same silly thing. There is a very big misconception about what colors dogs can see. For what I was told by many Vets, depending on the dog themselves, most dogs can see almost every color - just not as clear as we can. They see blur images. BUT they can see black, white, blue and red clearer than must other colors.

I don't know why people say that but they say that dogs can't watch TV either. My dogs go crazy over the laser pointer too and they watch TV for long periods of time. They cock their heads from side to side and sometimes lay in front of the TV for hours...watching it. I always wondered if they took a dogs eyes and put them in a person to see if they can only see in black and white. If not how do they really know. Dogs can't talk to tell you if they only see black and white. I think that both facts are wrong.

Dogs can ONLY see in black and white.
It's not the color your dog is chasing, as is evidenced by the fact that he chases both blue and red. It's the tiny pinpoint of light that the laser pointer creates.

Ok...first off its a myth that dogs only see in black and white. While its true they cannot see all colors (green is one of them) they can indeed see colors. Does anyone else besides me watch the Discovery Channel? There have been shows about this specific topic recently. Scientists have learned that they do see colors although the hues are a bit different than we see them. It is correct that dogs see things mostly in black or white or shades of gray, but they can distingush other colors, reds and blues, the color is just muted like they've been blended with grey.

Why is that a stupid question? I have heard the same thing and always wondered if it were true. But, in the case of the laser pointer, isn't it possible he just sees a dot of light moving about?

Most humans have the ability to see all the different colors of the electromagnetic spectrum, and consequently perceive all its' colors. [The color that is perceived is a result of the visual system, and not the spectrum itself.] Animals, such as the dog, are often thought of as being at a disadvantage by not being able to see all the hues of the spectrum. Evolutionarily however, the dog and the human each developed the visual system that worked best for them. Humans have depended on their diurnal ability and a sense of color throughout time to help them find food. Dogs on the other hand, were not originally diurnal animals, until humans domesticated them. Consequently, the ability to see at night was originally more important to the dog than color. After all, their prey is often camouflaged with the surroundings, so they are unable to rely on color vision cues as heavily as humans do to find food.
The retina of the eye is lined with both rods and cones in humans and dogs. The rods are much more prevalent in both species, but even more so in the dog than the human. The rods are adapted to work best in low light and are used for motion detection. The central retina of the canine eye contains about 20% cones, while humans have an area of 100% cones called the fovea. The cones work best in mid to high levels of light and have the ability to detect color.

I have a German Shep, too. I asked her if she could see color, but she won't answer.
Science says dogs can only see in black and white....but since no one but the dog has ever seen through the dog's eyes...and since my dog won't talk...I guess the evidence will remain inconclusive.
Btw, don't shine the laser right at your dog's eye! It WILL burn his eyes.

Yes; dogs ony see in black, white, & shades of gray. He's just going after the light, it has nothing to do with the color.

He just noticed the point on the wall or something. It might be hard to notice if you're color-blind, but dogs probably can see it.
