Do dogs laugh
You bet they do!
But before you can hear the laughter, you must first learn to speak dog. And to do that, you must develop a deep rapport and find a point of mutual respect and understanding. You must learn to read his or her every emotion, and eventually to come to know well your dog’s heart. (Ron MacInnis from https://ronmacinnis.com/things-i-learned-from-a-poodle)
