Description YOUR PUPPY IS NOT A DOG – THEY NEED SPECIAL NUTRITION – IS A HUMAN BABY FED LIKE AN ADULT? Obviously not. Babies have fragile digestive systems, small jaws and no teeth, so they can`t bite into an apple, for example. This makes it easier to understand why puppies also require a different diet to adult dogs. Diet during the growth period plays a key role in puppy`s future morphology and health. ROYAL CANIN Giant Starter food made for giant puppies with adult weight from 45 kg and over. Mother dog during gestation and lactation – weaning puppies up to 2 months old.
