Yes, puppy food is a "hotter" diet higher in protein and carbs. It is formulated for a growing puppy that needs the extra nutrition. An adult dog may gain excessive weight if fed a puppy formula regularly. The higher protein content may also put undue stress on the older dog's kidneys. If possible, feed then separately or take up the puppy food if you free feed.
