I am searching for a king german shepherd in u.k. I need to locate top breeders. Could you please contact me at mr_mandeep_pawar@hotmail.com

No such breed (pedigree) in the UK.  Therefore there will be no "top" breeders

Can find a King Shepherd in the Bruce Fogle book, it appears to be another designer cross, but that may be wrong as that particular book has been wrong before. Looked on the AKC site and it is not listed, never heard of it in the UK, but don't hold your breath. ;)
