I would stay away from PUPPY food all together for a newfoundland!! the only puppy food i would ever give my newfie is Eagle Pack. Large breed dogs cannot take the large amounts of protein most puppy foods have. Large breed dogs needs to grow at a slow and steady rate- look for foods that have around 23% protein and 12% fat. Most Newfoundland owners feed their dogs Adult foods. I have a 14 week old too! Just curious, how much does your pup weigh? My girl is on Canidae and loves it. I also boil potatoes, carrotts, brocolli and brown rice and mix it in with her food

Can you tell she's spoiled!
