I remember noticing King laughing. It came as no surprise to me when I read that article when it came out. People look at me crazy when i say that dogs laugh.

I guess I've heard Koli laugh a few times, but it's nothing like King's. That boy had one heck of a sense of humor. Sometimes he could get me laughing really good. Rather than trying to pick apart what was so darn funny I'd just roll with it.

I really can't put my finger on what they laugh at, but i can say their sense of humor is very different than humans'. It's a more simplistic just enjoying life kind of thing. Sometimes they just laugh because they are happy.
