Other Organizations
The Kennel Club (UK) maintains standards similar to the FCI with emphasis on the breed's companion nature and distinctive coat. The Canadian Kennel Club follows standards closely aligned with the AKC version but with metric measurements. The Australian National Kennel Council emphasizes the breed's suitability for apartment living and adaptability to various climates. Most breed-specific organizations worldwide stress the importance of the characteristic flowing coat, round eyes with warm expression, and the distinctive "chrysanthemum" facial hair pattern. Common elements across all standards include the emphasis on temperament as a primary breed characteristic, the importance of proper coat texture and length, and the breed's role as a companion animal rather than a working dog. Regional variations typically focus on size parameters and grooming presentation requirements, with some organizations being more specific about acceptable color combinations and markings.
