Walter the Farting Dog Goes on a Cruise -- William Kotzwinkle, Paperback

Everybody is having a great time on a cruise . . . until a terrible odor permeates the ship. All signs point to Walter, and so he is first banished down below, with the stinky cheeses, and then into a lifeboat to float behind the ocean liner. Then catastrophe strikes! How long will the great cruise ship and its frightened passengers be marooned on the high seas? About as long as it takes Walter to digest that cheese!
