All puppies’ digestive tracts are a bit different & dietary changes will occur as they age. If you’re able to, give them food for “puppies” (very different nutrient levels from adult food). Then take them off of it after they’re 1 yr. old (since they’re big breed). They may have been allergic to the grains etc. in NutriLife All Gold (Brown Rice, Pearled Barley, Oat Meal, White Rice, Brewers Dried Yeast, Alfalfa Meal). Also ask your vet if a full thyroid panel test would be a good idea (increased metabolism with concurrent weight loss issue).
Wellness CORE Grain-Free Puppy Formula is a great choice. Orijen Puppy Large Breed Grain-Free Dry Dog Food is outstanding. But as I said, it’s all trial and error until A) you like what you’re buying & B) you see outstanding stools & weight formation that’s appropriate.
If you’re not already, spread out the meals as evenly as you can during waking hours, small portions equal to the daily amount (or what they’ll consume) 3 to 4 times per day. It’s easier on their tummies.
