Well, this is kind of sh*tty, isn't it?

The city of Naples, Italy, is implementing a plan to take DNA tests from dog poop to catch people who don't pick up after their pets, according to The New York Times. If it turns out to be your dog's turd on the sidewalk, you'll be fined 500 euros. That's about $690.

Here's how it works: First, dogs must be registered and have cheek swabs taken. This is how officials collect their DNA. (In Naples, they're relying on blood samples, the Times notes.) When a small sample of poop is found, it gets sent to a lab to be analyzed. If it belongs to your dog, get ready to pay up.

“What we’ve seen is, when you start hitting people in their pocket they start paying attention," Moses told CBS Dallas Fort Worth.
