Nutrisource Grain Free Lamb Dry Dog Food by Tuffy's - 15lb Bag | High Protein, Hypoallergenic Kibble for All Life Stages - Perfect for Sensitive Stomachs & Active Dogs

We tried maybe a dozen different all natural grain-free dog foods. Some were excellent and others were pretty good. Our local natural pet supply store recommended this brand and OMG! Our dogs absolutely LOVED it! With other dog foods, they loved it in the beginning and then seemed to get tired of it after several weeks and we would have to change it up. They've been eating NutriSource now for about a year and still attack it with a vengeance at every feeding.I haven't done the math, but while this is more expensive than some of the others... The serving size is smaller to provide the optimal nutritional value so we use less of it and a bag lasts longer than the cheaper foods. My sense is that this is probably comparable or better on a cost / serving basis.
