Carbohydrates play an essential role in enhancing body function in dogs and cats. Sugars and starch that are used in ROYAL CANIN diets, are useful and easily digestible form of energy for growing puppies. Dietary fats serve as the most concentrated source of energy in a balanced diet, and lend palatability and texture to puppy’s foods. Protein plays a vital role in healthy puppy development by forming and renewing tissue, muscle and the skeleton. Essential amino acids cannot be made by the puppy's body in sufficient amounts for healthy functioning and development, and therefore must be present in food.
There are two types of minerals required for healthy development. Macro-elements such as calcium, phosphorous and potassium enable a number of key functions in the puppy’s body, including healthy bone growth, transmission of nerve impulses and muscle metabolism. Vitamins are needed for a wide range of biological and developmental functions including: Immune and cognitive function Cell function and repair Reducing inflammation Fat metabolism Blood clotting Brain and liver function. A puppy is less able to store water soluble vitamins such as vitamin B, in particular thiamin, and riboflavin in its body and therefore it is critical that these vitamins are part of their regular daily diet.
