This one is not funny, rather Cute!  ^_^  This dog seems to Really Love This baby!  ^)^ 

( Some dogs become protective over their owner's babies, they do it instinctively because they see that a baby is the smallest & weakest family member in the Whole House that needs lots of care & love!  ^_^ )

( And they just know it! - I even saw a video where a dog was Smart Enough to give a human baby a toy when it was crying - & it calmed down! :) ... And another video: when a baby was crying - the dog started to howl together with it to show how compassionate he is! XD )
