I know this for many years and have always been very satisfied, whether for puppies, adults or seniors. Compared to other brands, I saw the need to give less for the dog to be satisfied, resulting in significant savings because in the long run, this is expensive. Easily digestible, this food has never caused problems with my dogs (I am amateur breeder) and brilliance of their dress is proof. I recommend this brand. But the only problem is that I will raise the relative difficulty to procure.
