The service, branded PooPrints, is a very simple, Mayer said.

The first step is to register the DNA of all dogs in the community by collecting samples of their cheek cells using a pair of sterile swabs, Mayer said in an email. The second is to collect a sample of feces and send it to the lab for matching.

An attorney advised Kansky that condo trustees could enforce existing condo rules by requiring all dog owners to submit their animals for collection of DNA samples. Dog owners paid a one-time fee of $59.95 for the initial DNA testing for the database. Subsequent lab tests of dog droppings that end up identifying the offending animal result in a $50 testing fee plus a $100 fine.

So far, one resident dog has been identified as an offender.
