Growth is an essential stage of life for your young Pug. For this reason, it's critical that the nutrients in your puppy's food support its growth. ROYAL CANIN® Pug Puppy is specifically formulated to meet your puppy's nutritional needs and is suitable for puppies up to 10 months of age. This critical period of growth is when your puppy's immune system gradually matures. An antioxidant complex found in ROYAL CANIN® Pug Puppy supports the puppy's natural defenses. Included in this are antioxidants like the vital vitamin E. It's critical that you support your dog's skin health from an early age because the Pug breed has short hair and folded skin, which can retain unwanted humidity and become warm.
