I have 3 dogs and I have been feeding them Kirkland brand dog food from Costco for the longest time. I recently discovered a pet store in the city of Frisco called The Paw Depot and the nutritionist told me that there's actually bad chemicals in the Kirkland food and he recommended me some natural food from his store. I love it ! I noticed that my dogs are even losing some weight and their fur is even nicer. This store is awesome and if you happen to live in Dallas, Texas then I recommend you check this store out.
