Do dogs have cone cells in their eyes?

Yes, dogs do have cone cells in their eyes, but in fewer numbers compared to humans. Cone cells are responsible for color vision, and while dogs primarily see in shades of blue and yellow, they have a limited ability to perceive reds and greens. This means their color vision is dichromatic, unlike humans, who are trichromatic and can see a wider spectrum of colors. Overall, dogs' vision is adapted for detecting motion and seeing well in low light rather than for color discrimination.
