A dog owner owned a dog of little monetary value. One day, the dog disappeared, and the owner placed the following advertisement in the newspaper: “I will pay $500 to anyone who finds and returns my dog.” Before reading the ad in the newspaper, the neighbor found the dog in his backyard late the next night. The man took the dog inside, intending to return it in the morning. Shortly before he returned the dog, the neighbor read the dog owner’s advertisement in the morning newspaper. If the neighbor returns the dog is there an enforceable contract?
