What Does This Mean to You and Your Dog?
Dogs see different colors than humans do, so choose toys for them that feature the colors they can see. Dogs may not be stubborn or stupid if they can’t find a toy you threw because it was in a color they couldn’t see. When throwing a ball or bumper for your dog to retrieve, choose something blue and yellow instead of red or orange to help them discriminate between the two objects.

Dogs see color differently than humans. Dogs can see yellow and blue, and combinations of those colors.
This renders a lot of the world grayish-brown to them.
Are Dogs Color Blind?
Dogs only have two color receptors in their eyes, which means they can’t perceive reds or greens. Dogs are classified differently by experts as either color blind or not colorblind in the way that everyone seems to think they are. Dogs don’t just see in black and white like humans do – they see a color spectrum similar to that of humans with red-green colorblindness
Dogs can be colorblind and may not be able to see some colors. Dogs with red-green color blindness have difficulty seeing shades of green and red that are close together on the spectrum. Dogs with blue-yellow color blindness have difficulty seeing shades of blue and yellow that are close together on the spectrum. Dogs who are dichromats (only see one type of color) may also have problems distinguishing between different colors, but this is less common than problems with either red-green or blue-yellow color blindness.
There is no known cure forcolor blindness in dogs, but certain types of glasses can help a dog see better in certain colors.
What Colors Can Dogs See?
Dogs can see colors as a result of their species’ ability to see red and green light, which is called dichromacy. However, dogs cannot see blue, which is why they cannot see the sky and why they do not have blue eyes. Dogs only have two cones in their eyes that perceive color, meaning that certain shades of reds, greens, yellows, and oranges are lost to them. This doesn’t mean they don’t see the color altogether, just like a person with red-green color blindness can still tell you what color a firetruck and a banana are.
The only difference is that a dog’s color spectrum just isn’t as wide as ours! Dogs can see colors including red, yellow, green, blue and violet. Dogs’ color vision is not as good as humans’. Certain colors may be more noticeable to dogs than others.
Color blindness in dogs is rare but can occur if one or both parents are carriers of the gene for color blindness and their puppy inherits the gene from one or both parents (usually 50% chance). . In order to help your dog see as many colors as possible, keep his environment brightly lit and avoid giving him objects in dark colors. Dogs can see a range of colors including blue, yellow, orange, and red. Dogs’ color vision is better than humans in the short-wavelength (blue and ultraviolet) range.
Dogs see best in bright light and prefer to stay close to their caregivers when outdoors. Certain breeds of dogs are known for their exceptional color vision, such as the sighthound dog or Australian shepherd dog. There are a few diseases that can cause changes in a dog’s eyesight, including distichiasis (a condition where hair grows on the back of your dog’s eyelids), glaucoma (an increase in pressure within the eye), retinitis pigmentosa (a progressive degeneration of the retina), and keratoconjunctivitis sicca (a dry eye condition).
If you notice any changes in your dog’s eyesight, make an appointment with your veterinarian.
The Black and White Vision Theory
The belief that dogs only see in black and white is attributed to National Dog Week founder Will Judy, who wrote in a 1937 training manual that it was likely that dogs could only see in shades of black and gray. Researchers in the 1960s perpetuated the myth by hypothesizing incorrectly that primates were the only animals capable of perceiving color. This belief persisted about dogs until fairly recently when, in 2013, Russian researchers challenged the question, “Are dogs color blind?” They proved that dogs can see and distinguish between yellow and blue.
Dogs are very nearsighted with their vision estimated to be about 20/75; this difference in vision between humans and dogs contributes to their unique perception of colors. Dogs have a wider field of vision than humans.
Dogs are better at seeing fast movement, which makes them good at spotting fast-moving prey.
What Does This Mean for Your Dog?
This means that your dog is going to be charged with a crime that is punishable by death. Brightly colored dog toys, beds, and collars may appeal to human aesthetics, but they have no impact on your dog’s preferences. Dogs can see well in the dark and perceive colors differently than humans.
Selecting brightly colored pet gear could help your dog find objects faster amid natural surroundings.
How Your Dog’s Eyes Work
Your dog’s eyes are not just for seeing the world around them. They also help your dog to navigate. Your dog’s eyes are called the pupillary reflex. This reflex helps your dog to read the world around them. This is how your dog can tell the difference between light and dark, and to see objects as they come towards them. It connects the eyeball and the brain, and it carries electrical impulses from the eye to the brain, where those signals are processed to form an image.
The retina is inside of the eyeball and it functions to receive light and send those signals to the brain via the optic nerve, where they’re processed to form sight. Rods are one type of photoreceptor cell in your dog’s retina, and they’re sensitive cells that work mostly to catch movement or see in low-light situations. Cones are another type of photoreceptor cell that mainly help with color vision.
