There is a man shipwreck on an island

There is a man shipwrecked on an island and he is all alone, accept for a German Shepard and a goat. He has enough supplies to live healthy from the sunken ship and plenty of shade to protect him from the sun. Though the lonely nights started getting to him and eventually he starts to take a fancy to the goat. Though every time he tries to get close to it the German Shepard growls at him. This goes on for almost a month. Then one day a plane crashes over the island and he sees a women fall into the water. He swims out and pulls her back into shore and saves her life. She offers him anything in return for saving his life, and starts to undress herself. The man stops her though and kindly asks her to take the dog on a long walk instead.
