Purina Pro Plan Adult Large Breed is a chicken-first dry kibble built for large dogs, with glucosamine and EPA fish oil for joint support. It delivers 26% minimum protein and 12% minimum fat, a moderate profile for big, less active dogs. It suits owners of large adults who want a mainstream, widely available formula with joint ingredients. Against premium grain-free large breed foods it uses corn, wheat and poultry by-product meal, which some owners avoid; against budget kibbles it adds glucosamine, EPA and taurine.
