They can hunt prey 20 times heavier than themselves.
The bush dog has undergone evolutionary changes, including reduced body size, a shortened skull, and fewer molars. It has only 38–40 teeth, the lowest number among canids.
Their urine smells like vinegar, hence the name “vinegar dog”.
The bush dog is the most social of South American canids, hunting and living in small packs of 4 to 10–12 individuals. Occasionally, they form monogamous pairs.
The bush dog was long considered extinct, known only from fossil remains found in Brazil. It was not observed in the wild because the animals are highly elusive.
The bush dog has webbed feet and is an excellent swimmer.
It hunts in packs and can drive prey into water.
In captivity they have lived about 10–14 years.
Litters usually contain 3–6 pups.
They are diurnal.

العمر

The bush dog experiences several developmental stages, beginning with the “Embryo” stage where the fetus develops within the mother. The young are born blind, covered in dark fur, and feed on their mother’s milk inside a den; their eyes open between 1 week and 3 days and 2 weeks and 2 days of age. The species begins to walk between 2 weeks and 4 days and 4 weeks. A typical lifespan for the bush dog is from 5 to 15 years, with a maximum recorded lifespan of 14 years and 1 month, and a theoretical lifespan ranging from 7 to 14 years and 1 month. The female reaches sexual maturity between 7 months and 3 weeks and 1 year. The adult stage, characterized by hunting behavior and the ability to reproduce, lasts from 10 months to 13 years and 8 months.

Bush dogs measure in height from 17.8 centimeters to 3.5 meters, with a body length ranging from 57 to 75 centimeters; their mass varies from 5.19 to 5.93 kilograms. During the embryo stage, the body mass is between 1 and 15 grams. The young, in the infant stage, have a body mass of 150 to 450 grams and a body length of 15 to 25 centimeters. Adult bush dogs weigh from 5 to 8 kilograms and have a body length of 57 to 75 centimeters.

الموطن

Bush dogs inhabit tropical moist forests that are always hot and humid with large trees and vines, as well as terrestrial forests, grasslands, steppes, and tidal zones. The species lives in areas with elevations up to 2 kilometers. The climate is consistently hot, with little precipitation in winter and more rain in summer; it can be very hot and very humid year-round with nearly daily rainfall, hot with heavy rains in summer and little precipitation in winter, or hot with frequent rains but occasional dry periods.

مأوى

Bush dogs are found in forests near bodies of water and use dens for protection, reproduction, and rest. The species’ dens provide shelter for these purposes.

الجغرافيا

Bush dogs are found in the Neotropics, Afrotropics, Australasia, and Palearctic biogeographical realms, inhabiting Bolivian yungas, wet forests of Kaketa, wet forests of the Guiana Highlands, wet forests of the Guiana foothills, wet forests of Napo, and wet forests of Solimões-Japurá.

التغذية

The bush dog is a predator that hunts in groups, pursuing prey both on land and in water, and employs an active hunting strategy involving group hunting. The species’ diet includes capybaras, agoutis, pacas, birds, reptiles, large mammals, small mammals, and other reptiles. Young bush dogs feed exclusively on milk. The bush dog hunts in packs by pursuing its prey. Its daily food requirement ranges from 400 grams to 0.7 kilograms. The species’ prey includes pacas, agoutis, nine-banded armadillos, and woolly porcupines. In some cultures, the animal is consumed, but it is not considered halal or kosher.

تكاثر

Bush dogs inhabit terrestrial environments and develop exclusively on land, away from bodies of water; their young develop in nests built on the ground or close to it, sometimes in underground burrows. The gestation period for bush dogs is 2 months and 1 week, resulting in a litter size of 3 to 6 live young that are born on land. A male and a female form a pair, and the female gives birth to the young in a burrow. Both parents bring food and protect the offspring, although when near freshwater, such as rivers, lakes, ponds, or swamps, only the mother exhibits parental care. Bush dogs reproduce through sexual reproduction, always involving fertilization without generational changes. The species has an interval between reproductions of 8 months to 1 year, and reaches maturity from 1 to 2 years of age.
