I came across an interesting article today. [url]http://www.psychologytoday.com/blog/canine-corner/200911/do-dogs-laugh[/url] Laughter used to be considered a singularly human behavior. Then, people like Jane Goddall who spent tremendous amounts of time observing different animals, noticed the behavior in monkeys. Konrad Lorenz, a nobel prize winning ethnologist, has suggested that dogs laugh, too. He pointed out a certain sound pattern they make when playing. I know that dogs smile and show joy. Their tail wagging and goofy faces tell us they experience happiness. But, do they laugh? What do you think about this? Are dogs capable of laughing? Have you noticed laughing in your dog?
