The scent membrane is called turbinate and it contains the nerves that process olfactory details to the brain. With such a huge quantity of receptors, a dog can detect the unimaginable level of scents. Humans have something close to 50 lakh receptors and we use it to detect a staggering one trillion colors.Ĭanines have two hundred and twenty million olfactory receptors.īloodhounds have three hundred million receptors compared to one hundred and twenty-five million in Dachshunds.

People would still collar and microchip their dog with appropriate tags.ĭogs use their nose much effectively than we use touch and sight to comprehend and understand the world. Without a proper collection of all these dog nose prints, it appears unlikely that this could become a major identification program.
