The Bush Dog (Speothos venaticus) is a canid found in Central and South America, including Panama, Colombia, Venezuela, Bolivia, Peru (West of the Andes), Ecuador, the Guianas, Paraguay, northeast Argentina (Misiones province), and Brazil (from the Amazon rainforest to the state of Amazonas). In spite of its extensive range, it is very rare; it was originally discovered as fossils in Brazilian caves and thought to be extinct. It is the only species in its genus, Speothos.

In Brazil it is called cachorro-vinagre ("Vinegar Dog") or cachorro-do-mato ("Bush Dog"). In Spanish-speaking countries it is called perro vinagre, zorro vinagre ("Vinegar Fox"), perro de agua ("Water Dog"), or perro de monte ("Mountain Dog").

The Bush Dog has soft long brownish-tan fur, with a lighter reddish tinge on the head, neck and back and a bushy tail. The underside is dark, sometimes with a lighter throat patch. Adults typically have 5575 cm of head and body, plus 13 cm of tail, and weigh 57 kg. Legs and snout are short relative to body length: the typical height is only 2530 cm. The teeth are adapted for its carnivorous habits, and uniquely for an American canid, the dental formula is

Bush dog are one of three canid species with trenchant heel dentition, a unicuspid talonid on the lower carnassial molar that increases the cutting blade length.

It is a carnivore and hunts during the day, preferably in wet savannahs and tropical and equatorial forests. Its typical prey is the Paca (Agouti paca), a large rodent. Although it can hunt alone on occasion, the Bush Dog is usually found in small packs of up to 1012 individuals, which can bring down much larger prey. It may be the most gregarious of the South American canid species. It is a good swimmer (thanks to its webbed feet). It uses hollow logs and cavities (e.g. Armadillo burrows) for shelter. Pack-mates keep in contact with frequent whines, perhaps because visibility is poor in the undergrowth where the animals typically hunt.

The gestation period is 63 days, and a litter can have up to six dark grey pups. Lactation lasts approximately 8 weeks. The Bush Dog is sexually mature at 1 year and lives for about 10 years.
