There are now special diets for giant breed puppies. For optimal health, feed your giant breed pup this special diet until he is 12 to 18 months of age. Once your puppy has reached the age for a diet change, gradually begin changing his diet by feeding Â¼ adult food and Â¾ puppy food for a few days. Then add Â½ adult food and Â½ puppy food.
