Philotrox was named by Macdonald (1963).[2] It was synonymized subjectively with Enhydrocyon by Swisher (1982); it was revalidated by Carroll (1988), Wang (1994) and Wang and Tedford (1996). It was assigned to Canidae by Macdonald (1963), Carroll (1988), Wang (1994) and Wang and Tedford (1996).[3]

Morphology

Two specimens were examined by Legendre and Roth for body mass. The first specimen was estimated to weigh 12.8 kg (28 lb). The second specimen was estimated to weigh 13.8 kg (30 lb).[4]
