DNA-testing dog poo: Spanish city on the scent of owners who don't pick up

Tarragona has threatened to use a DNA database of registered dogs to match droppings found on the street to dog owners

Spain's north-eastern city of Tarragona has threatened to use DNA analysis of dog droppings to track down owners who fail to clear up their pet's mess.

The coastal Mediterranean city would work with a local university to create a DNA database of registered dogs that could be used to identify their owners, said Ivana Martinez, the city's city councillor for public spaces, on news radio Cadena Ser.
