It didn't take long for the scene to sour inside the Anoka County government center after a dog and its owner joined a crowded queue of voters.
Canine diarrhea soon struck, leaving behind an irksome cleanup and the discovery that the dog had no service training allowing it to be in the building in the first place.
The hard truth, as county Administrator Jerry Soma puts it: "It was just a pet."
The messy mishap from 2016 spurred county officials to act. Anoka County now restricts animal lovers from toting ordinary pets into county facilities. From statehouses to corner stores, government officials and business owners across the country are trying to crack down on the number of people who misrepresent pets as service animals and weighing penalties for those flouting rules that restrict which animals may go where.
More animals than ever are being brought into restaurants, stores, hotels, airports and shared spaces. Some have been trained to do tasks for people with disabilities and are granted public access under state and federal law. But others are ordinary pets that owners are passing off as service animals so they can take them to places they don't belong.
There is no official national registry for legitimate service animals. With service vests available for anyone to purchase online, abuses can abound.
"I know it's increasingly been on people's minds that something has to be done because it's just rampant," said Margot Imdieke Cross of the Minnesota Council on Disability. "Maybe if there was a penalty for fake service animals, people would realize this is a big issue."
The topic, animal law experts say, comes larded with plenty of confusion over what does and does not qualify as a service animal.
