Monday’s interesting Dog Fact!

Dogs can see in the dark because of the tapetum lucidum, a mirror-like membrane in dogs’ eyes. There are light-and-motion sensitive cells in the retina that are referred to as rods, which can tell the difference between light and shadow. The tapetum lucidum rebounds the light that the rods didn’t absorb into the retinas so they can take in more light. Dogs have evolved to be able to see better in dim light, yet they can’t do so as well as cats.
