Protein levels don’t affect how puppies grow and there’s no real proof they affect kidneys in any negative way in a healthy dog. So there’s nothing wrong with nv puppy or Orijen puppy. As for the merrick have you tired adding water? Or toppers? Toppers can be anything from raw meats, plain cooked meats, or canned or pouched dog foods. It’s a good way to entice them. Also make sure your meals are scheduled the same times. I have a chocolate lab in the family. He eats canidae all life stages multi protein food and he eats at 6 am and 6pm everyday at the same time. If you’re lab is rejecting food it’s very possible he doesn’t like it. Most labs will inhale anything lol.
