Nebelung variants are not to be used in any Russian breeding program
All Nebelung variants (ie. shorthair) maybe used in Nebelung breeding programs with those not used to be desexed before homing as pets.
It is recommended that Nebelung Variants without a Nebelung parent are DNA tested to prove whether they carry the longhair gene. The application for registration should be accompanied by the DNA test certificate and those proven not to carry the longhair gene shall be over stamped “Does not carry longhair”.
