Animal Laughter
Can dogs "laugh" ? Recent research shows that dogs can tell each other when they want to play. They make a special sound-a kind of "laugh." Paychologist patricia Simonet recorded the sound. Then she played it back to dogs to assess their behavior. "All the dogs seemed to like the laugh," says Simonet. So do animals have a sense of humor? If laughter is a clue, then perhaps the answer is "yes!"
