Dogs See Fewer Colors Than Humans Dogs' vision is similar to humans who are red-green colorblind. They can see shades of blue and yellow but struggle to distinguish between red and green.
Dogs Have Better Night Vision Dogs have a higher number of rod cells in their retinas, which helps them see well in low-light conditions, making them excellent at navigating in the dark.
Wider Field of Vision Dogs can see nearly 250 degrees around them, while humans have a field of vision around 180 degrees. This allows dogs to be more aware of their surroundings.
Dogs Have Better Motion Detection Dogs excel at noticing movement, even at a distance. This heightened sensitivity is useful for detecting prey or responding to a threat quickly.
Dogs' Eyes Are More Sensitive to Light Thanks to the tapetum lucidum, a reflective layer in their eyes, dogs can see better in low-light conditions. It also causes their eyes to glow in the dark.
Dogs' Eyes Adjust More Slowly While dogs have good night vision, their eyes take longer to adjust to changes in lighting compared to humans, especially when moving from bright to dim environments.
Dogs’ Vision Helps with Communication Dogs rely on eye contact to express emotions and communicate with their owners and other dogs. They use their eyes to signal whether they are friendly, scared, or aggressive.
