So who wins?

My friends dog is barking at the doorbell. On incoming foreign barked, and the call - no. They decided to hold a demonstration lesson. Husband (a pretty solid man with a bald head and abdomen, weighing about 100 kg) went on all fours at the door. The wife came out and rang the doorbell. Husband barking. Wife entered and gave her husband a piece of cheese. Husband chewed and smacked his lips.
 The dog looked at them as idiots. When the cheese is over, they have changed.
 Wife, slim and graceful woman, got on all fours at the door, and her husband went out and started ringing the doorbell. Wife barked. Husband opened the door, gave his wife sausage slices. However, he still kicked the dog, which continued to stare at them as idiots.
 When my wife grind two kilograms of raw sausages, cut into small pieces and hoarse from barking, and her husband, swore and said, "Do not useless, Dora learns to bark never", and they both went into the room, the dog ran rushed into the kitchen and dragged out a full a bowl of dry food to her mound, has set spouses and sat down on the mat, demanding the continuation of the show.
