All Lucy Pet Formulas for Life  diets are formulated to be complete and balanced for all life stages, including senior pets. Our formulas are nutritious with high-quality proteins, carbohydrates, fats, and fiber, as well as the essential vitamins, minerals, supplements and antioxidants necessary for growth and development. One very important factor in senior pets is to maintain a healthy weight. Obesity is the leading health issue in senior pets, so we recommend following our feeding guidelines based on the age and weight of your pet. Equally important with senior pets is to ensure regular exercise to keep them fit and healthy.
