I have a 12 year old German Shepard/Huskey mix with dry/allergic skin issues and a 5 year old German Shepard who is over weight. I have just taken them off of Iams ( senior and Healthy Weight). The salesperson at Petco recommended Natural Balance Sweet Potato and Venison for my older dog with skin issues. She also recommended Nature's Recipe Lamb and Rice for my overweight dog. The reviews do not look good for Nature's Recipe.
