13 Fun Facts About Dogs You Probably Didn’t Know

2. Teeth and Eyes

A fully adult dog has 42 teeth. This makes it a bit easier for the dog to chew their food than it is for us humans, who are equipped with only 32 teeth.

But it’s not only the dogs’ teeth that separate it from humans. Dogs’ eyes are also quite different from humans, as they have to see completely other things than we do. The cornea of the eyes has two types of cells, rod-cells, and cone-cells. Cone-cells are responsible for the sense of color, and the rod-cell manages the eyes night vision.

Dogs are equipped with a lot of rod-cells, which is why they are remarkably strong for seeing in the dark, where humans have more cone-cells, which makes us better at seeing colors.
