As with most stray dogs, no one can say for certain how his life on the street began, but he managed to find a family all on his own. A few years back, he just showed up one day at a police post in the city of Petrópolis, Brazil. The cops he encountered there were immediately smitten by him, and they adopted the dog as one of their own.
He goes by several nicknames, but officially he's known as Xerife (Portuguese for "sheriff").
"They have put together a little house for him and they treat him with a lot of affection," Creuza Villardo Wurch, a neighbor, told The Dodo. "Xerife's loyalty to the police is amazing!"
But the faithful dog offers more than just a friendly face.
