Have you ever watched little puppies play? Funny sight, right? We came across an interesting fact that puppies “boys” while playing with puppies “girls” behave like real “men”. They often succumb to them during the game, despite the fact that they usually have a clear physical advantage.

The manifestation of such chivalry on the part of a male puppy signals to his partners in the game that he has no serious intentions, but just wants to play. Similar behavior has also been reported in red-necked kangaroos, several species of monkeys and, of course, in humans.
