The African wild dog (Lycaon pictus) is a social canid that occurs patchily across savannas and semi-deserts of sub-Saharan Africa. It typically forms packs of around 10 individuals that hunt cooperatively and have a high success rate in pursuing and bringing down prey. It is an obligate carnivore that mainly preys on ungulates, and strong bonds and mutual aid behaviors are observed within packs. Breeding centers on the dominant pair; gestation lasts about 69–73 days and litters are large (around 10 pups). Numbers are declining due to habitat destruction and disease, and the species is listed as Critically Endangered (IUCN Category I B).
