Senior recipes are designed to be suitable for those dogs over 7 years old. A senior diet is designed to help support the joints, have higher fibre content in order to help 'keep things moving' and have reduced energy content in order to help prevent weight gain in those golden years. A careful blend of Glucosamine, Chondroitin and MSM helps support cartilage for healthy joints. These recipes include L-Carnitine, an essential amino acid which can help maintain a healthy weight and lean muscle mass.
