The pedigree database is mostly geared towards the European lines of dogs- German showlines and European working lines. Not very many recent American showline dogs are on there. So no, it's not an immediate red flag. Also, the entries aren't automatic, people must input them. Occasionally there are inaccuracies but it's overall a very good resource. The GSD Pedigree Database is NOT an official registry. Dogs registered through the SV or AKC do not go online there automatically. In other words, it is not like a searchable AKC database. Most of the more common lines are pretty well filled out, some dogs are missing info, some have incorrect info.
