Similar to a person’s fingerprint, a dog’s nose print is unique and is sometimes used as identification.

Dogs are known for their legendary sense of smell, and with good anatomical reason. Their noses have as many as 300 million receptors, while humans have about 5 million.
Evidence from a Bloodhound’s remarkable sense of smell is admissible as evidence in a court of law.

When it comes to taste buds, people are the top dogs. Humans have approximately six times more taste buds than dogs, around 9,000 vs 1,700. While some dogs are picky eaters, their overall tendency to eat even questionable fare comes from ancestral instincts when the species survived as scavengers in the wild.

A Greyhound can beat a cheetah in a race, depending on how long the race is. The cheetah can run up to 70 mph for about thirty seconds, but a Greyhound can run 35 mph for up to seven miles. So the cheetah would win a short sprint, but the Greyhound would prevail in a longer race.

You don’t need the scientific method to prove there’s something special about our wonderful canine companions. And the fact of the matter is that as long as we’re willing to learn, dogs will always have something to teach us about ourselves and the world around us.
