My English black lab, Abbie, is a smiler. When she greets you, up go the lips and she shows off her pearly whites, while wagging her tail in delight.
Alas, those who don’t know her, think she’s baring her teeth in aggression. In the 9 years we’ve had her, she has only growled once at another dog and that lasted about 10 seconds before they were playing together like puppies.
Just wondered if it’s just her or is it more common than I think?
