Dogs are some of the most expressive creatures on the planet, and their smiles are no exception. But do dogs really smile in the same way that humans do?

For example, a dog might show its teeth and gums in a relaxed way, with its ears perked up and its eyes bright. This is often interpreted as a sign of happiness or contentment.
