The bridge to a strong adulthood. Royal Canin Giant Junior is specifically designed for the second stage of growth in giant breed puppies (adult weight >100 lbs). From 8 months to 2 years, your puppy focuses on building muscle rather than height. This formula provides an adapted protein content to support healthy muscle development, while Glucosamine and Chondroitin continue to protect the joints of your growing giant. With clinically proven antioxidants and prebiotics, it ensures a smooth transition into their massive adult frame.
