Origin
Cynarctoides is derived from the Nothocyon and gave rise to Borophaginae, a short-face, heavy-jawed canine usually massive in size. Cynarctoides shared part of its period with a variety of bear dogs like Aelurodontina, Tomarctus and the giant mustelid genus of bone-crushing canidae.
Taxonomy
Cynarctoides was named by P. O. McGrew in 1938 and R. L. Carroll in 1988 and assigned to the family Canidae. Xiaoming Wang later placed it in the Borophaginae genus of Phlaocyonini.
Morphology
Fossil specimens of two individuals' body mass were examined by Legendre and Roth.
