I know what you mean! My pup was running full throttle at the park playing chase with another dog, he looked to the side when he shouldn't have and ran full speed into a bench.
He cried for about 5 seconds and then acted as if nothing happened! I had to do my best not to coddle him while I checked to make sure he was ok, lol.
