MAXI formulas are designed for the large breed dog throughout their lifetime. Large dogs are treasured for their incredible working abilities, and prove to be wonderful herding, tracking, rescue, guard and assistance dogs. These powerful and devoted dogs can often suffer from digestive sensitivities, joint pain and even cardiac issues. Royal Canin MAXI formulas address the needs of the large dog throughout its lifetime—from the large dog’s longer growth period, to nutrients to help limit inflammation of the joints and highly digestible proteins to ease digestion. MAXI Weight Care is for large breed dogs with a tendency to gain weight over 15 months old.
