Sniffing is his hobby! The adventures of an untrained police dog with bite, charm and a great need for petting! File number: barked! The world of the true-hearted Aspro, perhaps the smartest and best dog of all, is turned upside down from one second to the next. While routinely playing with sticks, he loses the boss, as he calls his master, in an explosive accident. Slightly intimidated and still dazed by the loud bang, the loyal male is taken in by a young, pregnant policewoman - her husband is not amused. But the three (soon: four) warm up to each other, even the new boss can't resist in the end and falls in love with Aspro. A dog that detects more than just bones Soon Aspro will even be allowed to accompany the boss to work at the station - because there is so much to experience in the world outside the basket. And because he's now a policewoman's dog, Aspro thinks he's a police dog - and he's more than ready for exciting cases! Undercover on four paws, it is easy for Aspro to work. So he single-mindedly uncovers injustice, confronts pickpockets, burglars, poachers and rescues a drowning man - and all this for honor and treats! He also helps his boss to get the nasty headache under control. What more could you wish for than such a good-natured friend with a fine snout? Absolutely nothing. Finds Aspro. Snooping is his hobby.
