Are Dogs Colorblind? GUEST BLOG

Today's question is answered by one of my students, Taylor.

Dogs can see color, however they cannot see every color. During the day, humans use cells in their eyes called cones to see colors. Humans have three different types of cones, which allows them to see the colors red, blue, and green. However, dogs only have two cones, which only allows them to see the colors blue and green.
Dogs are not colorblind in the sense that they only see black and white, but they do only see certain colors due to the lack of one cone in the eye.
