This is sad... Life and death is invulnerable... And especially when people say that dogs are human best friend.
Even when the dog is old, it will do its best to stand up on its own feet. And even when he can't stand anymore, he will still remember that he need to protect his owner, forever there by his side.
I teared while watching this. Just by looking at it (not listening), I already cried. This is too touching... Its not romance or whatsoeva but loyalty...
These kind of drama/movie/media can't make me not tear...
