Large- and giant-breed adult dogs have more than just big bodies and bigger appetites. Eukanuba recognizes this and offers Eukanuba Large Breed Adult to support their special needs. Eukanuba Large Breed Adult contains natural sources of Glucosamine and Chondroitin Sulfate to help support joints stressed by a large-breed dog's greater weight and contains L-Carnitine to help your large-breed dog naturally burn fat instead of storing it. Eukanuba Large Breed Adult also has appropriate levels of a natural vegetable fiber to help aid digestion and helps your dog have appropriate stool volume for easier cleanup. FOS, a natural Prebiotic, is included to support your dog's strong defenses from within the digestive tract. Eukanuba Large Breed Adult is made in a large kibble size designed for a large-breed dog's mouth.
