Recorded Dog Laughter Calms Dogs

Researchers at the Spokane County Regional Animal Protection Service in Washington state say the long, loud pant is the sound of a dog laughing, and it has a direct impact on the behavior of other dogs. When they played the sound of a dog panting over the loudspeaker, the gaggle of dogs at the shelter kept right on barking. But when they played the dog version of laughing, all 15 barking dogs went quiet within about a minute — via Boing Boing
