I can only say why I feed Orijen and that's because there is no rubbish in it, there are no added cereals or rice both of which are unnecessary in a dogs diet all they are are fillers, also the cereal which is carbohydrates turns into sugar which can make a dog hyper. I don't particularly want to feed my dog a food where the main ingredient is carbohydrates, at least 40% of the majority of dog foods on the market are made up of carbs, some are even higher. There are no derivatives of any kind and there are no e.c. permitted additives as there are in some of the Purina brands. I used to feed my last girl Burns and if I had to change food that is the one I would go back to.
