Wikipedia
The bush dog (Speothos venaticus) is a canid found in Central and South America. In spite of its extensive range, it is very rare in most areas except in Suriname, Guyana, and Peru; it was first identified by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. The bush dog is the only living species in the genus Speothos, and genetic evidence suggests that its closest living relative is the maned wolf of central South America. (Note: this has recently been disputed, its closest relative may be the African wild dog ). The species is listed as Near Threatened by the IUCN.
In Brazil it is called cachorro-vinagre ("vinegar dog") or cachorro-do-mato ("bush dog"). In Spanish-speaking countries it is called perro vinagre ("vinegar dog"), zorro vinagre ("vinegar fox"), perro de agua ("water dog"), or perro de monte ("bush dog").
