Well, to get him PAL registered, he has to be neutered. If neutered, he cannot be shown in conformation. Showing in conformation is not a beauty contest, it is a contest to how near a dog meets the standard for the purpose of passing on the best genes. Altered dogs are not eligible.
But you can show in obedience, rally, herding trials, and all kinds of other things. Frankly, he is not what is going in either the AKC ring or the SV ring, that doesn't mean he isn't a beautiful dog, it's just not what will go in those rings, specialty or all breed, and there is no point in pursuing it to be disappointed. If you want to show, pick a breed in the middle of the breed popularity, so you have a chance of getting a show prospect, and enough entries to show. Showing GSDs is particularly hard because of their popularity, the mesh of lines, politics. I think one of the mods shows, dog fairies.
Let's put it this way, you don't get a pretty puppy and say, let show it. You start long before that pup is born, getting to know the folks that are showing and finding the breeding you want, paying for the show prospect, starting at eight weeks with setting the pup up and getting it used to handling, berry checks and all that, and all the time letting your breeder guide you while you rub elbows with the other people that show and judge in GSDs. The breeder can help you know what judges to put your dog in the shows. You can become very poor very fast in dogs. Only best of breed and above gets points. Not like in obedience and rally, if your dog does everything to a minimum score at least, it qualifies and you can easily title in three ring appearances. But in the show ring, only Best of Breed gets points, and you need so many points, and two majors, show under at least two judges, maybe more, to get that CH. I think it is something the SV does better. They give each dog a rating, VA, V, SG, G and then the number that they finished in the class. So if your dog finished 3 in excellent select, it would be VA3, but I think that is only the sieger show.
Anyway, getting a PAL and showing in agility or Rally or obedience, herding, freestyle -- so many sports like fly ball, dock diving, herding, nose work, barn hunting. Find what your dog excels at and go for it.
