puppy drink milk by bottle?

puppies (or a small/weak puppy who can't nurse) need you to give them the nutrition that will keep them alive. Bottle feeding is usually the the fist way of your answer.
If you're faced with a tiny puppy (or a whole litter of them) who aren't able to nurse from their momma, it can be a very scary situation.
You might be wondering how on earth you're going to keep them alive let alone thriving!
