An Israeli city is using DNA analysis of dog droppings to reward pet owners who clean up after their pets and punish those who don't. A six-month trial program launched this week, in the city of Petah Tikva, to tackle the dog mess problem in a high tech way. The program asks dog owners to take their pets to a veterinarian, who then swabs its mouth and collects DNA. The city will use the DNA database it is building to match droppings to a dog and identify its owner. Owners who scoop up their dogs' droppings and place them in specially marked bins will be eligible for rewards of pet food coupons and dog toys. Those who leave the poo on the street face fines. I wonder what sin you had to commit in a previous life to find yourself the official dog poop examiner of Petah Tikva, Israel.
