premium dog foods

Is the Costco brand Kirkland Super Premium Dog Food really "Super Premium" or better than a mark of the grocery store?
With two dogs go through a dog food fast enough, so I'm trying to find something that is not real expensive, but still a quality diet. I have a Costco membership and realized his "Super Premium Lamb & Rice Adult" dog food today. They also had a chicken and vegetable mixture. Ingredients looked good – no by-products, etc, but I am not an expert when it comes to analysis of individual foods. It feeds no mark their dogs? Has your experience good / bad? Thank you! The first ingredient was the lamb, the lamb was, flour and rice was the third second ….
Yeah, yeah yeah yes yes! Kirkland is the generic version of one of Diamond's food (I do not agree that the style of the top of my head). It is a very high quality food. I give it to my four dogs and have seen a significant reduction in skin and hair problems, and the four that I have thick, full coats over their same race friends eating Purina Pro Plan. We used to feed lambs based food but were told that the chicken we change decreases flatulance and have not had a problem. I recommend it.
