"EXCELLENT may only be awarded to a dog which comes very close to the ideal standard of the breed, which is presented in excellent condition, displays a harmonious, well-balanced temperament, is of high class and has excellent posture. Its superior characteristics in respect of its breed permit that minor imperfections can be ignored; it must however have the typical features of its sex.
VERY GOOD may only be awarded to a dog which possesses the typical features of its breed, which has well-balanced proportions and is in correct condition. A few minor faults may be tolerated but none of a morphological nature. This award can only be granted to a dog that shows class."
"CACIB – Certificat d’Aptitude au Championnat International de Beauté de la FCI
The only dogs which can be taken into consideration for the CACIB are those which have been awarded "EXCELLENT 1st". A CACIB can only be awarded if the dog in question has been assessed as being of superior quality. The CACIB is not automatically and compulsorily linked to the "EXCELLENT 1st”."
