Blue Buffalo is far superior to puppy chow. Puppy chow is mainly corn and not a whole lot else. Blue Buffalo isn’t the best of the best by way better than puppy chow. Also if he’s overweight and also malourished at the same time how is that possible?? A lot of vets hate Blue Buffalo which I totally understand. Seems to give a lot of dogs diahrea. But a family member of mine has have her chocolate lab on blue for 7 years since he was a puppy and he’s the picture of health. So if he’s having good bowel movements, strong nails, soft fur not shedding much he should be just fine. But also try the puppy cans of food for now instead of the kibble. Just for a couple weeks if you can then I would switch to their large breed puppy food if you think the dog with get over 50 lbs.
