The amount you feed of any food has to be based on the number of calories the dog needs and the number of calories in the food, so throw out any method of determining amount that does not take into account that some foods have more calories than others. Next, it is very important to keep large and giant breed puppies lean while they are growing, so slim is good as long as he isn’t looking emaciated. The 4 cups plus topper that you are feeding is very close to their recommendation, so I would say you are probably feeding very close to the perfect amount.
So the only question I have for you is:
When are you going to post a picture?
