Natural Balance (I think) makes a potato and duck for pups as well as adults. If not, I'm pretty sure you can use the adult for puppies. I had to switch to this for Chance because he has horrible allergies to brown rice and foods loaded with wheat.
Here's an ingredient list:
Potatoes, Duck, Potato Protein, Canola Oil (preserved with natural mixed tocopherols), Potato Fiber, Natural Flavor, Dicalcium Phosphate, Calcium Carbonate, Sodium Chloride, Salmon Oil, Flaxseed, Potassium Chloride, Choline Chloride, Taurine, Natural Mixed Tocopherols, L-Carnitine, Yucca Schidigera Extract, Vitamin E Supplement, Iron Proteinate, Zinc Proteinate, Copper Proteinate, Ferrous Sulfate, Zinc Sulfate, Copper Sulfate, Potassium Iodide, Thiamine Mononitrate (Vitamin B-1), Manganese Proteinate, Manganous Oxide, Ascorbic Acid, Vitamin A Supplement, Biotin, Calcium Pantothenate, Manganese Sulfate, Sodium Selenite, Pyridoxine Hydrochloride (Vitamin B-6), Vitamin B-12 Supplement, Riboflavin, (Vitamin B-2), Vitamin D-3 Supplement, Folic Acid.
