Who truly knows whether they’re actually showing their happiness or just trying to breathe and/or pass gas either way there is nothing like a dog smile. Of course we human’s want to believe that it’s actually a sign of happiness and this is one time I will follow the masses. For when a dog smiles it’s hard not to smile back and in turn the happiness (or gas) flows all around us… let’s hope it’s not the later. A dog smile can help make those common daily chores more fun for all those involved. It’s time you put on your dog smile even if you don’t have a tail.
