A new app, called Smart Snout, can track a missing dog by treating its nose as one would a fingerprint.
It’s thought every dog’s nose has a pattern that, when coupled with the shape of its nostril openings, is distinctive enough to identify it.
The app is free to download; but it comes with an annual cost, if you want to register your dog’s details.
Once your pup’s information is in the app, if the animal were to be lost or stolen, then recovered, the finder could simply scan the animal’s snout.
Then, the owner and the finder would be alerted to the dog’s identity so the dog could get home safely.
The app was only launched about eight weeks ago. But it already has more than 2,000 subscribers.
