So, both the mother and the father are (or were) working law enforcement dogs? Is it possible one of them is a Malinois or Malinois/GSD cross? Some breeders in Europe commonly cross GSDs, Malinois and Dutch Shepherd, and export them to the US for law enforcement purposes--since these dogs are purely for work and not show, registration papers do not matter. If this is indeed a crossbred puppy, you won't be able to get AKC papers, but you could still ask for a pedigree on the sire and dam, if you can find their owners.
It's possible he is just a very light sable, purebred GSD, in which case you may be able to register the pup with AKC.
As far as breeding goes? Forget it--believe me, there is so much you have to do with the dog before you can even think about breeding him, that it just isn't worth it unless you are sincerely dedicated to the German Shepherd Dog as a breed, your dog as an individual, and dogdom in society as a whole. Since pet overpopulation is epidemic, you really don't want to bring more pets into the world unless you have a darn good reason to--and at the very least, only healthy specimens free of genetic disease should be chosen to breed. In order to ascertain this, you must run expensive tests and x-rays on your dog.
Then if all that checks out, you have to ensure that your dog matches the breed standard in terms of conformation, temperament, and working ability. This is done through training, showing, testing, working and trialing in events like obedience, tracking, Schutzhund, SAR, etc. Also the dog should be looked at by a neutral, discriminating and experienced eye, a conformation expert like a judge or longtime breeder, to make sure he is put together the way he should be.
Aren't you tired just reading that?
I haven't even started on how to campaign your dog for stud, how to choose the right females, the actual act of breeding, stud fees and guarantees...
And if anyone ever told you that owning a stud dog is "easy money", I could refer you to a few reputable breeders with stud dogs who will be happy to tell you otherwise!
