If you people think dogs don't smile you just don't know a thing about dogs. I've had at least a dozen dogs that actually smile. I'm talking happy as a lark, wagging their tails, not scared at all, bearing their teeth because their happy dogs. My current dog smiles sometimes. I've had dogs that smiled every time they saw me. I had a Cairn terrier that would do that. I currently have a feist that will smile sometimes but not often. It's obviously a smile when you see a dog smile. The video above is gone so I know nothing about it. I just know that dogs do smile and often. If you know how to make your dog truly happy you'll know how to make your dog smile.
