For as long as I can remember, it has been common knowledge that a dog has a much superior sense of smell than we do. However, to my surprise, a dog's scent sensitivity is several thousand times greater than that of a human. Scientists have recently uncovered the secret behind our furry friends extraordinary ability. Canine's have, as do other keen-scented mammals such as rats and rabbits, a specialized anatomical structure in their nasal cavity known as the Olfactory Recess. It is located beneath their eyes and takes up half of their interior nose. The Olfactory Recess is a large maze of twisted and coiled airways that are not found in humans and similar primates. Scientist have created a computer model of a canine nose to truly understand why they have such superior smells. In order for the nose to breath in the same manner as a dog, the scientists used data collected from special muzzles which they attached to several dogs. The discovery has lead to breakthroughs in the advancement of scientific invention and understanding.
