Do Dogs Laugh?

    Research done by Patricia Simonet at Sierra Nevada College in
Lake Tahoe looked at laughter sounds in dogs. Simonet’s team investigated the question by standing in
parks with a parabolic microphone that allowed them to record the sounds that
dogs made while playing from a distance.

In describing the laughter sounds of dogs she says that, “To an untrained human
ear, it sounds much like a pant, ‘hhuh, hhuh.” When the recordings were analyzed
she found that that this exhalation bursts into a broader range of frequencies
than does regular dog panting. She confirmed the positive effects of this laugh
sound in an experiment on 15 puppies, which romped for joy simply upon hearing
the recorded canine laugh. More recently she was able to show that these same
sounds helped to calm dogs in an animal shelter.
