Dogs often look so cute when they hang their tongues outside their mouths. It’s a sign of calmness and happiness. This will often happen when you go out and play fetch or when you are out for a walk. That said, their doing this excessively simply shows that they have “hanging tongue syndrome,” a common thing with bulldogs, dogs that have flat noses or even boxers.
