the other factor that you are not considering is the age of the dog. Up until now, "Blade" has been a growing, maturing boy. He's starting to slow down now, and giving a choice, will self regulate during hot weather, AND during periods of non growth, meaning, during periods he doesn't need to have as much food. You will probably have a much different looking dog in six months than you have now, and then again, a even different "er" dog after ANOTHER six months. Enjoy the process, don't worry, and feed him what he wants, not what you think he needs!
