When playing with female puppies, male puppies will often let them win, even if they have a physical advantage.



Why do they do it? According to researchers who have studied this behavior, the male pups do this because it prolongs play time with the females. If they used their advantage to win, the play would be over. They also get to spend more time with the females and to create more of a relationship with them - a relationship that may help them secure a future mate.
