We created CANIDAE® Life Stages Large Breed Adult Duck Meal, Brown Rice & Lentils formula especially for big dogs with big appetites. Duck meal has high levels of omega 3 fatty acids, which play an important role in reducing inflammation within joints—an important benefit for large breed dogs. Lentils help satisfy big appetites and are a satisfying source of sustained energy. And lower fat and protein levels help large breed dogs achieve and maintain optimal weight.
