"Herr Bello" tells the tale of 12-year-old Max, who is jealous of his widower father’s attempt to find new love with Frau Lichtblau. Max’s best friend is his dog, Bello, and thanks to magic the animal turns into a human being, Herr Bello. But if manners, or is it clothes, make the man then Herr Bello is most definitely still a dog! Furry-faced, cat-chasing and bad-breathed chaos ensues until it all comes good in the happy end as, thanks to Herr Bello, Max learns to accept the newest member of his family.
