My 8-week-old puppy is currently eating Pro Plan Puppy Chicken and Rice, which is what he was being fed before. I'd like to switch his food soon. My other dog rotates between Acana, Orijen, and Wellness Core, and I'm really pleased with how she does on them. Are there any drawbacks to feeding a young puppy a high protein food such as Orijen (38%)? Especially considering what he's been eating (28%)? I've also considered Wellness and TOTW's High Prairie Puppy, or even Fromm. Thanks in advance!
