In AKC shows (both rally and obedience) head carriage is NOT supposed to be judged. Head up, head level, as long as the dog is in heel position there shouldn't be any points off. Now that said, I prefer head's up heeling.....but a 10 month old PUPPY shouldn't be doing long periods of heeling yet anyway, heads up or not. And the structure of the dog determines what is comfortable for the dog, and THAT is very important.
