Hi Brain,
buy some “Malaseb” Medicated shampoo & bath weekly to wash off any allergens that may be on paws & skin, Malaseb is excellent for itchy skin, red paws, yeasty smelly skin, environment allergies & is mild enough to use daily….

Have a look at “Canidae” they also make “Under The Sun” a cheaper range of dog formula’s, there’s Under The Sun, Puppy formula with healthy ingredients, page 1, bottom right..
I think it’s Ok to feed a growing large breed pup a kibble that has healthy grains, like brown rice, oatmeal etc & also has potatoes, sweet potatoes, peas, blueberries, beans, carrots etc grain free ingredients as well, I don’t know what these kibbles are called they have both, I’ve noticed a lot of large breed puppy formula’s don’t have the bad old ingredients like corn, wheat, gluten meal & soy but will have healthy grains now…
there’s Canidae Pure Foundations puppy grain free, page 3, top left
then there is Canidae’s new vet formulated All Life Stages, Large Breed, Turkey Meal & Brown Rice formula on page 4, bottom right…..
or there’s Canidae Life Stages large breed puppy, Duck Meal, Brown Rice & Lentils page 5

I would look for 2 large breed kibbles that both are different brands & have a different protein & rotate between the two…..A rotational diet allows a better chance of providing a more complete & balanced diet…..This is particularly important for young animals, the idea is that by allowing short exposure to a wider variety of protein types, the immune system is primed to a larger range of potential allergens which strengthen the immune system & may reduce the risk of allergies or symptoms developing….
I feed 1 brand kibble for breakfast & I feed a different brand & protein kibble for dinner..
