PooPrints works by creating a community database the DNA of each dog on the property. DNA is collected via a non-invasive, painless cheek swab of the pet. If pet waste is left behind, a small sample can be collected and matched back to the correct dog and its owner. While most pet owners are doing the right thing by picking up their pet waste, this program deters the few pet owners who do not. Other benefits of the online registry include a lost-and-found service with positive proof of identification, online storage of veterinary records and vaccine history, and discounts on commonly used pet supplies.
