Jerusalem has a dog poop problem. It’s apparently so bad, city officials are going high-tech to deal with it. They’re planning to compile a DNA database of city dogs and when they collect the illegal poo, they’ll be able to track down the offending pups. And the owners pay, according to The Daily Mail.

In a statement, the municipality said it would first be collecting saliva samples from dogs in the city before inputting them into a citywide database.

“The municipality pilot project calls for establishment of a database of dog DNA to allow us to reduce the soiling of pavements, parks and public spaces,” the statement said.

Once the DNA database has been compiled, the city will conduct testing to see whether the samples can be effectively matched to dog droppings found around the city.

Israeli daily newspaper Haaretz said the municipality hoped to get saliva samples from around 70 to 80 percent of the 11,000 dogs registered in Jerusalem.
