During your large-breed puppy's growth period, they need enough calories and the right nutrients for their developing skeletal, nervous and sensory systems. This can be a challenge for puppies of this size: because they are susceptible to bone and joint problems, high levels of calcium or vitamins can be harmful. As younger puppies gradually lose the '˜antibody shield' provided by their mother's colostrum, they also need optimal protein to build their own immune system. ROYAL CANIN® Maxi Puppy in Gravy is specially formulated to support the nutritional needs of large-breed puppies. This formula is suitable for 2 to 15-month-old large-breed puppies that should reach an adult weight of 26-44kg
