Note that the division of the Canidae family into “true foxes” (Vulpini) and “true dogs” (Canini tones) may not be consistent with practical relations and the taxonomy of a Several species of foxes and dogs are still controversial. However, recent DNA analysis indicates that Canini and Vulpini are valid clades, but exclude two genera: Nyctereutes and Otocyon. These are species in the base group of the Dog family and are not closely related to either Vulpini or Canini. (Some evidence suggests the same thing for the genus Urocyon.)
The genera Speothos and Chrysocyon are original members of Canini, but can also be placed in their own branches. The genus Cuon may in fact be part of the genus Canis and there is also some evidence that the genera Alopex and Fennecus may not be valid branches but are part of the genus Vulpes.
