What Are the Five Senses of a Dog?

A dog's five senses are smell, hearing, sight, taste and touch. While these are the same five senses that humans have, dogs use them in different ways, and they are much more sensitive than humans are, especially when it comes to their sense of smell.

Dogs rely heavily on their sense of smell. They use it to hunt for food, recognize their territory and recognize their pups. The sense of smell is so keen in dogs, humans use it to help locate lost persons, hidden drugs and even dead bodies.

Dogs' sense of taste is similar to that of humans, and their main taste sensations are sweet, salty and sour. Dogs primarily use their sense of sight to focus on depth perception to help them chase their prey. When compared to human vision, a dog's sense of sight is inferior. Contrary to the popular myth, dogs do not see only in black and white, but they are likely color-blind to the red-green spectrum.

A dog's second-strongest sense is the sense of hearing. They can hear sounds in a much greater range than humans, and muscles in their ears allow them to focus their hearing towards a sound for even better efficiency. A dog's sense of touch is important because it allows the dog to sense changes in temperature or pressure against their skin that could indicate danger.
