This document discusses the pros and cons of choosing a dog versus a pig as a pet. It shares a story of an airman who bought a potbellied pig but ended up getting injured by it after the pig piled rugs in the hallway and squealed for food. While both dogs and pigs can make great pets, the essay argues that choosing a pet requires considering one's lifestyle, finances, and living arrangements to pick an animal that is suitable. Dogs tend to have a minimal impact and are often easier to care for than pigs, which require more attention and space.
