Does your dog laugh?

Yes dogs do make a panting rhythm that acts like a laugh. They have done studies. If you listen to a dog pant after or during play you can hear that it is not a "hot" pant but has a different sound. When this panting is played to other dogs, they will react in play mode. Therefore it kinds of works like a laugh that lets other dogs know it is fun!

My Peke is not the laughing type. He's more of a growler. But my son's Husky laughs all the time.

No, my dogs don't laugh, but they smile alot.
