The standard work includes all 350 dog breeds internationally recognized by the FCI, as well as around 160 additional breeds. For quick identification, reference, and finding the right breed, the dogs are organized by size categories and within each size category by relatedness and similarity. The register also includes all synonymous breed names. Each portrait features a typical photo and all important information about the breed's origin, character, and suitability. The bonus with the book: the free KOSMOS-PLUS app with images, videos, and interesting reports.
