I am not sure what all the hype is about the nutrical,if your puppy is eating as good as he is I see no reason for it.Certainly if you have a tiny puppy that is not eating well you should use it.But your puppy sounds like he is a great little eater
It is a great thing for low blood sugar and helps some of the tiny ones alot but yours doesn't sound like he falls in the category.I would just save my money
