Obviously, there are dogs acting like humans, and I think this dog is one of them.
As we can see in this GIF, the dog loves this newborn baby so mush. And he cares about him so much.
The dog decided to cover the sleeping baby to feel warm; I think the weather is so cold.
I do not know if there is smarter than this dog, I think he is the most kind and cute dog I have ever seen.
