Dog foods with Grains,additives,chemicals cause skin,stomach problems. Try Taste Of The Wild,Bison or others like it.... Google it and you will see. I used to cook for my dogs, which ended the stomach-skin issues. After 2007, people woke up and demanded food without cheap grains. I have been feeding my dogs this food for 3,1/2 yrs. NO problems. Don't just believe the "Natural" claims, but get familiar with what's really in these dog foods.
