The owner will, at a directed place, be told to play actively with the dog. Preferably pull-game with a cloth or a ball, but if the dog doesn’t want to play, you’ll have to try, to get another kind of activity going between the dog and the owner. Meanwhile, (with 15 seconds interval) there will be fired to loos shots with a 9 mm. gun in about 20 meters distance from the dog. Here the owner needs to talk to and encourage the dog, in order to describe if the dog interrupts, resume or maintain its activity with the owner. There will be described the dogs ability to maintain its activity or its escapetrend from the sound.
