Did you know both cats and dogs noses are unique, like human fingerprints. It’s becoming more common to take nose prints of dogs in case they’re ever lost or stolen. Hmmm, interesting.

The reason dogs, or canines, are specially trained to help with police work such as taking down drug cartels or carriers, is because dogs have more than TRIPLE the amount of olfactory receptors in their noses as humans and cats combined! Humans have only about 20 - 40 million olfactory receptors, cats have between 40 - 60 million olfactory receptors, whereas dogs have about 220 million olfactory receptors in their noses. This means the olfactory bulb in a dog's brain is bigger than that of the one in humans and cats.These olfactory receptors give dogs the upper hand on having one of the best senses of smell in the animal kingdom; the Bloodhound being one example of the breed of dogs use in police work, as well as German Shepherds.
