Instead of enjoying his holidays, Little Dog needs to join his parents on their business trips. How boring! As his parents leave for their next trip, it happens: They forget Little Dog in the hotel. After a short moment of shock, he decides to stay. Maybe he can discover all the departments and learn how a hotel works? But what is this?!: Skinny greyhound Albert collapses under the weight of the suitcases, the liftboy chihuahua Maurice can hardly reach the buttons, the chef pug cannot cook and a huge black scary dog serves the very few guests of the hotel... Good, that Little Dog has an idea already! – And when his parents return after some days, neither do they recognize the hotel in which things suddenly work to perfection, nor their Little Dog!
