MICHEL MARTIN, HOST:
Good morning, I'm Michel Martin. For the past five months, residents of Vastogirardi, a village in southern Italy, had been troubled by a string of tire lashings. Was it a feud between neighbors, even the mafia? After setting up security cameras, police found the culprit, a dog named Billy. Billy had gingivitis, and vets believe he was biting the tires to relieve his pain. All's well that ends well, except for Billy's owner, who will likely have to foot the bill for all the damaged cars and hopefully get Billy some help. Transcript provided by NPR, Copyright NPR.
