Well for one that happened at my GDs home. Their female dog was in season and had a gentleman caller. The youngest one said look mom they are wrestling. Well the older said no there not. My GD wondering just how much he knew ask then what are they doing to which they replied getting ticks off her back. She was thrilled that he was still an innocent child and we live on a ranch and he has seen things born. Thanks to God there is still innocent children.
