The on-the-street people asking you these questions would not be people knowing enough to better the breed. My first long hair would get "Do you plan to breed her? I really want a long haired shep!" inquiries. Sorry no. There are plenty of people that do responsible breeding out there but I doubt that they are the people looking to mate their dogs with yours.
To do this responsibly you need to know a lot more about pedigrees than I do. You also have to have a bunch of health clearances (hips, elbows etc.) Hopefully at least a certain amount of performance titles if you want to sell a pup to anyone that tries to trial it.
