(CNN) -- A New Hampshire apartment complex is mandating that residents submit pet DNA samples.

Why? To check if any of them are abandoning their dogs' waste on the property.

"Ninety-eight percent do what they're suppose to do," property manager Debbie Violette said of her residents with dogs, "but there are some that don't and you don't know who that is. That'd be pretty foolish if they did that right in front of me."

Timberwood Commons in Lebanon, New Hampshire, says it is among a growing number of apartment complexes implementing PooPrints.
