What is the universal scientific designation shared by the Zuchon?

Canis lupus familiaris

The Zuchon, despite being a recently created crossbreed known by a trade name, belongs to the same scientific species as all other domestic dogs. This designation, *Canis lupus familiaris*, places it within the broader species *Canis lupus*, which also includes the gray wolf. The species level classification is determined by the ability of individuals within the population to interbreed and produce fertile offspring. Since the Zuchon results from crossing two established members of the domestic dog species—the Shih Tzu and the Bichon Frise—the resulting dog remains biologically classified at this subspecies level. This reflects a universal biological reality that supersedes human-defined breed standards or marketing labels.
