Dogs nose prints are as unique as a human’s fingerprints and can be used to accurately identify them. If you look closely at a dog’s nose, you will see lines forming patterns, just like fingerprints.
Just like the pattern of every person’s fingerprints are unique, each dog’s rhinarium has features that are unique to each dog. The rhinarium is the section at the tip of a dog’s nose; it’s a special type of skin that secretes moisture. The surface of the rhinarium is part of what gives dogs a superior sense of smell.
Few places in the United States have already adopted dog nose printing as a common way of identifying lost dogs. The Canadian Kennel Club has been accepting dog nose prints as proof of identity since 1938.
Other forms of dog identification include the use of a microchip being implanted in the dog, however many pet owners feel this is an invasive and painful way of keeping track of their furry friend.
