ProfessionalPupperPetter is an Imgur poster who works at a doggie daycare center in Seattle. That means that she's one of the few people on the internet to deserve their quirky username. PPP's shelter has 40 to 60 four-legged visitors a day!
The work at the daycare involved keeping the pack of dogs under control (they even have a time-out-place where a pupper can spend 15 minutes accompanied only by a blanket and a bowl of water), scooping up the dog poop, giving them their lunches (some owners pack some) and so on. Not a bad job, overall!
