The topic was closed so I could not get to you there. About the organic dog food. I feed my dog all raw meat and bones. I suppliment this with fish oil and Vitamin C, some veggies, but not much, and NO complex carbs. I switched her several months ago to pretty much what they call the BARF diet ( Bones And Raw Food ), after studying up on various dog diets.
You might want to check into this as well. Some googling, and a visit to your vet will give you the info you probably need.
Remember, commercial dog food has only been around since about the 1940's. So don't feel limited to what you can buy in a bag.
