Uh, this isn’t true. My dog literally smiles when she’s happiest (usually during belly rubs). Belly rub from yesterday. She rolls on her back, exposes her belly, and smiles bigger and bigger as I scratch:
And some breeds (like dobermans) do the stupid little smile when they’re happy, which includes showing their front teeth and usually a lot of wiggling. But I’ve never seen them doing it other than upright position, and I think they tend to squint their eyes too doing that, so whatever is going on the op picture does not look like that. But dogs showing teeth really has multiple meanings, the context and body language tell the rest
