Not only with the Aussies, but with GSD at the time of Ritintin, with Golden Retriver, with Dobermanns due that film ("the Dobermanns gang "what simply he destroyed the breed in fame and quality), I find that the television is a curse for any dog breed.
The worse is that when occurs an attack where a dog of these without temperament attacks and kills a person, the breed is the guilty, it is the breed that is aggressive the breed has that to be extinguish.
The pedigree unhappyly is not quality assurance in one breed, pedigree is easy of being gotten, the majority of the kennels does not make control of the registered litters, not only in Brazil, but in other places of the world, it has many no-breed (or totaly no-standard) with register of a pure dog breed.
In the case of the CzW and any another breed that is not "popular" (similar at Borzois, ovtcharkas, Lundehund...) finishes have problems in the shows(expositions) judgment due to the unfamiliarity on the part of the judges in relation to the standard of the breed.
But without doubts, the biggest problem for any breed is the stupid owners, this is similar at one snow ball whit the "fame"!
