This is why I caution my puppy families to feed their young puppies for growth, (not on the "lean side") so if they do get ill, or go off their food while teething, that they still have reserves to draw on. Think of it this way, would you place a growing toddler/child on a restricted calorie diet? No, you wouldn't, you let them play as much as they want, and feed them for energy and growth. I get through the fast growing phase with some extra padding on my puppies, exercise them appropriately, (no forced exercise, no long hikes, no long leashed walks on hard surfaces, etc...) and take the extra weight off them when they are done growing.
