Category:Canis lupus has four sub-categories. One of these is the taxonomic sub-category Category:Subspecies of Canis lupus. The other three relate to common name groupings within the species. Category:Wolves contains wolf-related articles such as Never Cry Wolf, Homo homini lupus, and Pre-caudal gland as well as links to the common names of wolf subspecies. Category:Dogs is similar for the domestic dog. While there are overlaps between the taxonomic sub-category and the common-name cultural sub-categories there is no redundancy as the two have different purposes.
