GREENSBORO, N.C.-- Lurking in the grass may be an unpleasant surprise.

"It's a huge nuisance and getting it on the bottom of your shoe is on the worst things to come home with," Carolina PooPrints owner Brock Kehoe said.

It happens when an owner doesn't pick up after their dog. If pet poo happens to you, Carolina PooPrings will respond to the scene and take a DNA sample.

"Our goal is to catch owners that aren't picking up after pets and hold them accountable for it," Kehoe said.

In order for this to work, every pet in a managed community must get a DNA sample on file with PooPrints.

"It's a constant problem," pet owner John Mattey said. "People walking with their kids - it gets stepped in. It's nasty."

The organization said they have more than 8,000 dogs registered in North Carolina alone. Now that some apartment communities are enforcing DNA testing of all dogs on the property, PooPrints said they have seen more owners cleaning up after their pets for fear of getting fined.

Some said adding DNA testing into the equation may be too much.

"As president of our homeowners association, we tell our residents to take a nice picture of the dog in the act," Mattey said.

PooPrints said the poo problem is much more than an ugly sight.

"The Center for Disease Control basically ranks pet waste along with toxic chemicals and oils," Kehoe said. "So if you wouldn't allow somebody to pour gasoline or motor oil on the ground, you shouldn't allow somebody to not pick up after their dog."

So far PooPrints said they have a perfect record of matching the doody to the dog.
