Do all dogs see in color?

No, not all dogs see in color. While they can see some colors, their vision is primarily dichromatic, meaning they have two types of cone cells in their eyes, compared to humans' three. This limits their ability to distinguish certain colors.

Here's what we know about dog vision:

* They see shades of blue and yellow: Dogs can differentiate blue and yellow hues but struggle with reds, greens, and oranges.

* Their world is less vibrant: Colors appear less saturated and distinct to dogs.

* They have excellent night vision: Dogs have a higher density of rod cells in their eyes, which are sensitive to low light, giving them better night vision than humans.

So, while dogs can see color, their world is quite different from ours, with less color variety and intensity.
