Cones provide color perception and detailed sight, while rods detect motion and vision in dim light. Dogs have rod-dominated retinas that allow them to see well in the dark. Along with superior night vision, dogs have better motion visibility than humans have.
Anxiety in dogs is a very common problem that can be triggered by a variety of situations, but are dogs afraid of the dark? According to the Blue Cross, it's not common for dogs to be afraid of the dark, especially because their night vision is much sharper than ours.
