I know the feeing, I went through that too. But like the Galathiel said, they'll train you to hand feed them.
You checked your puppy is healthy so now remember, he wont let himself starve.
Keep feeding him and take his bowl away after maybe 20 minutes if he ignores it. You can try giving him his bowl again a little bit later, if you can, like maybe an hour later if you can or want to. Or just wait until his next feeding and give him his food but dont leave it longer than 30 minutes.
You can try adding water to his kibble. That's supposed to help. Or you can add a little bit of raw meat or canned food or tripe or whatever you'd like as a topper, really, just to make it harder for him to resist so he'll want to eat from his bowl. If that is something you dont want to keep up, you can always phase it out after he gets used to eating from his bowl when you feed him.
