Puppies are born with their eyes closed. They don’t open them until about two weeks after they are born.
At first, their vision is blurry, but it gradually becomes clearer.

For a long time, scientists thought that dogs saw the world in black and white. But recent research suggests that dogs may actually be color blind.
Dogs have two types of color receptors in their eyes, but they don’t work the same way as the three color receptors in human eyes. This may mean that dogs see colors differently than we do.
Dogs Not Completely Color Blind
Dogs are not completely color blind, but their color vision is limited. Dogs can see colors, but their range of colors is not as wide as ours. They can see some colors that we cannot, but they cannot see all the colors that we can.
Dogs see colors differently than we do, and their color vision is not as sharp as ours. Humans have three types of cones in their eyes that absorb light. Dogs have two.
A dog’s eye has two types of cones: those that are sensitive to blue light and those that are sensitive to yellow light. The combination of these two types of cones gives dogs the ability to see some colors that we cannot see.
For example, dogs can see the color blue, but we cannot. Dogs cannot see all the colors that we can see because they lack a third type of cone that is sensitive to red light.
This type of cone is necessary to see the colors red, orange, and yellow. Without this type of cone, dogs cannot see these colors.
Plus, the colors that dogs can see are not as bright and vivid as the colors that we see. This means that their color vision is not as sharp as ours.
Dogs rely more on their other senses, such as smell and hearing, than they do on sight. This is because their color vision is not as strong as ours. Dogs use their other senses to help them navigate their world and to find food and mates.
Dogs See Colors Different
Dogs don’t see colors the same way that humans do.
Because dogs only have the two cones mentioned above, they can only see blue and yellow colors and can’t distinguish between red and green. Dogs can see some colors, but not as many as humans.
That doesn’t mean that dogs see the world in black and white. Dogs can still see plenty of colors, just not as many as humans. And due to their limited color palette, dogs likely see the world a little differently than we do.
So, while your dog may not be seeing the world in quite the same colors as you are, they are still seeing a world full of beautiful colors.
Dog’s Sense of Smell
Dogs are not color blind, but their color vision is not as important to them as their sense of smell. Dogs rely more on their sense of smell than on their sense of sight.
Dogs have a keen sense of smell, and they can use their sense of smell to track down prey, find mates, and communicate with other dogs.
Dogs also use their sense of smell to identify objects and people.
In fact, dogs have a special organ in their nose called the vomeronasal organ, which allows them to detect pheromones, which are chemicals that animals use to communicate.
So why do people think dogs are color blind?
It’s probably because they don’t react to colors in the same way that humans do.
For example, if you wave a red ball in front of a dog, they’re not going to react to it the same way they would if it were a green ball. They might not even react to it at all. That’s because red is not a color that is meaningful to them.
Dogs communicate mostly through body language and scent, so they don’t really need to see colors the way humans do.
So, while dogs are not exactly color blind, they don’t see color in the same way that humans do.
