I bet you won’t be able not to smile, enjoying these funny animals? Cheer yourself up by watching a selection of videos about funny animals. Scientists only throw their hands when they are asked: “Do animals know how to smile?”.
Indeed, science cannot give an accurate answer to this question, but it insists that man is different from animals in that he is able to smile. If we talk about the wild, the smiling face of the wolf indicates nervousness or submission to the older “in rank”.
But if this wolf smile more like a grin, Pets can smile sincerely and joyfully, just like people. So we have just to love them the way they are.
