Typhon (1976)

Two friends are trying to train a dog named Typhoon to work in the criminal investigation department. To draw attention to their ward, the guys let him loose on the policeman, and they themselves run away in fright. Having plucked up the courage, they come to the department to find out about the victim's health. He turned out to be quite healthy and explains to the boys how to train dogs properly.
