I this case I suggest to import a puppy from outside.
I know it can be more expensive but at least you can import a PUREBREED puppy: many Saarloos-mixes with fake FCI pedigree and dogs of dubious origin have been imported to Asia from european puppy-mills....
Before paying advantage money/picking up the puppy - check the parents in the database (
http://www.wolfdog.org/dbase) to be sure that they are really pure Czechoslovakian Wolfdogs...
