If animals can have this kind of love, what happen to humans?

If animals can have this kind of love, what happen to humans? This dog never gave up even after death of his friend or partner. He gave every single part of his last energy to revive him. And we call them animals, wow....

It is sad to say the lease, what I seen that caught my eye was not just the dog feeling his lost of his friend, but how the dog kept barking and then would look around for someone to help him out, and no one came to comfort him.
