Smile training is a great way to help dogs learn how to feel more comfortable in social settings. A dog’s natural instinct is to display teeth when it is feeling aggressive or defensive, but this may not be the best approach when meeting strangers or dogs of the same species. Using training treats and positive reinforcement, teach your dog how to display a friendly, relaxed grin. Reinforce the behavior every time it is seen.
Is it possible for dogs to smile?
A dog’s mouth is wider than its brain, so it’s difficult for them to understand other people’s feelings and to know what they’re thinking. That makes smiling and other expressions difficult for them. However, a dog’s lips do move when they’re happy or excited.Dogs can sleep most of the time they’re awake. As a result, their muscles are underdeveloped, and they can’t run or play as well as other animals. Instead, they move around by walking or running on all fours.
