Dog owners have always wondered how dogs perceive the world. It was believed for a long time that dogs could only see in black and white, but recent research has shown that dogs can actually see some colors. However, dogs do not see the full range of colors that humans can see and are similar to people with red-green colorblindness. This means that dogs cannot see the colors red and green at all.
Signs Dogs Can See Colors:
Dog owners can observe certain signs that indicate whether their dogs can see certain colors. Dogs may show a preference for toys of a certain color and reject toys that are red or green because these colors appear dull and hard for dogs to see. If you play fetch with your dog in the grass, using a blue or yellow ball will make it easier for your dog to find the ball. These signs can give you insight into how your dog sees the world.
Body Language:
There are various body language cues that dogs may exhibit when they see a color they can perceive. These cues include being alert, barking, tilting their head, raising their ears, and having their ears up. Other signs may include favoring one color of a toy over another, wagging their tail at the sight of a toy in a visible color, and losing toys of certain colors.
History of Dogs Seeing Colors:
For a long time, it was believed that dogs could only see in black and white. This belief originated from Will Judy, the founder of National Dog Week, who stated in the 1930s that dogs had bad vision and could only see basic outlines and shapes. In the 1960s, researchers claimed that only primates could see in color, leading to the belief that dogs also couldn’t see colors. However, in 2013, Russian researchers discovered that dogs can see a limited range of colors, including shades of yellow and blue but not red or green.
Science Behind Dogs Seeing Colors:
Dogs have a similar eye structure to humans, with rods and cones in their retinas. However, dogs have only two types of cones compared to humans’ three. Dogs lack the cones that allow them to see red and green, similar to humans with red-green colorblindness. Dogs have more rods than humans, which enables them to see better in the dark. They also have larger corneal lenses, allowing more light to enter their eyes in dark environments.
Dealing with Dogs Seeing Colors:
Understanding how dogs see colors can help dog owners make their pets’ lives easier. By purchasing toys and products in colors that dogs can see well, owners can enhance their dogs’ visual experiences. It’s important not to ask dogs to see colors that they are unable to perceive naturally. For example, using blue and yellow toys for playing fetch in the yard will help the toys stand out against the grass, while red and green toys may be lost. Realistic expectations should be set, and dogs should not be asked to see colors that they cannot see due to biological limitations.
Understanding how dogs see colors can help dog owners better cater to their pets’ visual needs.
Tips & Things to Know
1️⃣ Dogs can see some colors, but not all colors in the same range as humans. Dogs have limited color vision and cannot see red or green. It is important to understand the colors that dogs can see well and choose toys and products accordingly.
2️⃣ Pay attention to your dog’s body language when they see certain colors. Dogs may show signs of alertness, barking, head tilting, and raised ears when they see a color they can perceive. They may also favor toys of a certain color, wag their tail, or lose interest in toys of certain colors.
3️⃣ Dogs have different visual abilities than humans due to the structure of their eyes. Dogs have two types of cones instead of three, which limits their color perception. They have better night vision and a larger corneal lens, allowing more light to enter their eyes in the dark. Understanding these differences can help you interact and engage with your dog in a way that accommodates their visual abilities.
