I’ve Never Seen A Dog Do This! This Is Hilarious!The Alzheimer's Site
A dog showing her teeth – isn’t that a sign of aggression or fear? Not always, and certainly not for Gracie! Gracie is an adorable, rescued, and pretty clearly beloved golden retriever who has picked up a unique talent, and has been practicing for two years to achieve perfection.
(Gracie’s smile is generally known as a “submissive smile,” which just means she really, really, really wants you to love her. In some dogs, it becomes a habitual greeting – especially if reinforced with lots of petting and treats!)
