Growth is an essential stage in your Rottweiler puppy's life. It's the time of new encounters and physical changes. During this key period, it's particularly important to provide your puppy with nutrients that help to support optimal health. Suitable for puppies up to 18 months old, Royal Canin Rottweiler Puppy is specially formulated with all the nutritional needs of your young Rottweiler in mind. Because your puppy's immune system develops gradually, Royal Canin Rottweiler Puppy contains a complex of antioxidants including vitamin E to support your puppy's natural defences. This formula also helps to support muscle and bone development thanks to an adapted protein content and adequate levels of calcium and phosphorus. It contains L-carnitine. A combination of nutrients with high-quality protein (L.I.P.) and prebiotics (FOS) supports digestive health and the balance of intestinal flora, which contributes to good stool quality.
