hi northwind, nice dog.
you need stackhim a little better, the front legs need to be straight under him, he needs to be focusing forward and more alert and his rear needs to be brought in closer to each other.
however to give you a rough idea, Young looking male, nice type, good pigment, wide short ears, flat withers, bend in lumber spine, short croup, good rear angulation, upper arm should be longer and better anguled, shoulder should be longer, forechest should be more pronounced, underchest is very good. the pasterns should be firmer as well as the hocks.
i could be wrong but he seems young and is yet to achieve his mature body and muscularity. then again a better stock would show him much better
