GOLDEN VALLEY — The American Humane Society in the Twin Cities is adding photos of stray dogs it takes in to a database that uses facial-recognition technology to reunite lost pets with their owners.

The organization started adding photos to smartphone application Finding Rover’s database last week. Graham Brayshaw with the Animal Humane Society says it’s another tool in helping to find pets’ owners, in addition to collars, identification tags and microchips.

Dog owners can upload a photo of their pet’s face to Finding Rover in case they go missing. Someone who finds a lost dog could use the app to take a photo of its face, and the app uses facial recognition and location to look for matches.
