A new story by Paul Maar: Invisible dogs really exist - and so do real friends! Before Niko and Ole knew each other, each of them had an invisible friend: dog Snuffi belonged to Niko, pug Mucki to Ole. But now all of a sudden Niko and Ole are best friends, have a lot of fun and don't need their invisible companions anymore. The dogs don't want to believe what's happening to them: Does that mean they don't exist just because they're invisible? That can't be! And so Snuffi and Mucki set off together in search of a new human friend. With a lot of charm, wit and fantasy the ideal book for the first self-reading - lovingly illustrated by SaBine Büchner.
