Iams Proactive Health Large Breed Chicken & Whole Grain is an adult dry dog food built around real chicken as the first ingredient, with egg, corn and wholesome grains. It targets the big-dog concerns: calcium plus natural glucosamine and chondroitin for bones and joints, prebiotic fiber for digestion, and an omega-6 to omega-3 ratio for skin and coat. It is a mainstream grocery-and-club formula rather than a premium grain-free or fresh-food line, so it competes on value and a long feeding record. Owners of large adults generally report good palatability and firm stools, while some picky dogs and sensitive stomachs do not take to the corn-heavy recipe.
