Research has found that dogs have color-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of color vision that we do.
It is thought that dogs can see blues and yellows the best and that they are able to differentiate between various shades of blue and violet, but that they have difficulty distinguishing reds from green. They are considered similar to red-green color-blind humans.
yes
Dogs can see in colour but they don't see colour the same way as humans do. Dogs can distinguish between different colours, but they are also colour-blind as their eyes have a blue-violet range and a yellow-green range, similar to humans who have a red-green range. Therefore dogs are green-blind, resulting in dogs not being able to distinguish bewteen blue, grey and different shades of purple.
While dogs are essentially red/green colour-blind (unable to distinguish between these colours), they are significantly more capable of seeing objects in motion, even at great distance, and have enhanced night vision compared to humans.
It is a common misconception that dogs see only in black and white. Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do.

Actually, yes. Dogs do see color (meaning more than just black and white), just a lot fewer than normal humans do. Instead of seeing the colors of the rainbow as violet, blue, blue-green, green, yellow, orange and red, dogs see it as dark blue, light blue, gray, light yellow, darker yellow, and very dark gray.
Essentially then, this means dogs see the colors of the world as basically yellow, blue and gray. The colors green, yellow and orange look yellowish to a dog, and violet and blue appear as blue to a dog. Something we see as blue-green will appear gray to a dog.
Dogs have "red green" color blindness, i.e. they cannot distinguish between identically bright hues of these colors. They have limited blue-green perception.
Yes. Dogs are red/green color deficient because they only have two cone types, rather than the three, like humans. But they do not see only black/white and shades of gray.

Just like the cats like the lasers toys there are some dogs that also like the laser toys as well.
My dog watches tv when dogs are on it! Even when there is no sound! So I think that clearly shows that dogs can see things in 2D, like on a TV or in a mirror.A mirror image is considered 3d not 2d, so it is not the same thing. The dog is watching the TV because he can see the moving images of light. Not a picture similar to what we see.
Dogs look at lights because it catches there attention. They are trying to figure them out. Dogs are smart but human invented the light. ( but that's probually because we have opposable thumbs lol)
No, but they can hear through them much better than humans so will know what is happening. They can also smell things and recognize scents more than 1,000 times better than a human so if your dog knows you are on the other side of a wall, it is from those two senses and not the dogs x-ray vision.
Cat. Cats have an elliptical pupil which opens & closes much faster than round types (dogs/humans) and allows for a much larger pupil size. This in turn allows more light to enter the eye, giving the cat better night vision, not better in darkness but better at picking up light. No animal can naturally see in the pitch black but a cat can see better in minimal light.
If you see the beam, you are seeing the scattered light being reflected off particles in the air. Any light you actually see is no longer laser light, assuming you have sense enough not to look at it directly.
You can't see a laser beam crossing a room because the laser produces a narrow, focused beam of light that is not scattered easily. The light particles in the laser beam are not interacting with the air particles in the room, so there are no particles for the light to bounce off of and become visible to the human eye.
No, dogs cannot see infrared light. They can see some colors, but their vision is limited compared to humans.

To see a laser beam, you can use special materials like smoke or fog to make the beam visible. The light from the laser reflects off these particles, allowing you to see the beam.
Laser light.
In daylight: no At night: yes
You cant see it because it has a light and the tv has a light.
By definition, a laser travels at the speed of light. As soon as one sees it, it has already arrived via visual light.
Dogs can see ultraviolet light, which is invisible to humans.
You don't need laser light. Normal light will do, for many microbes. You DO need a microscope, since they are way too small to be seen with the naked eye.
The function of flash light is used to see the object in the darkest area.
