Which type of organization maintains stud books for hybrids like the Whoodle without having formal zoological standing?

Answer

Hybrid or designer dog clubs such as the International Designer Canine Registry (IDCR)

While the Whoodle lacks recognition from major international zoological or biological classification bodies, certain niche organizations exist specifically to track the lineages of these mixes. The International Designer Canine Registry (IDCR) is an example of a club that maintains its own stud books and records pedigrees for these designer dogs. This registration confirms lineage within the enthusiast community but holds no official standing when measured against the established criteria used by mainstream biological taxonomy systems.
