The African wild dog has very strong social bonds, stronger than those of sympatric lions and spotted hyenas, thus solitary living and hunting is extremely rare in the species. It lives in permanent packs consisting of 2–27 adults and yearling pups. These coat patterns are asymmetrical, with the left side of the body often having different markings from that of the right.īehavior Social and Reproductive Behavior Some specimens lack the white tip entirely, or may have black fur below the white tip. The tail is usually white at the tip, black in the middle and brown at the base. A white patch occasionally occurs behind the forelegs, with some specimens having completely white forelegs, chests and throats. The back of the head and neck are either brown or yellow. A few specimens sport a brown teardrop shaped mark below the eyes. A black line extends up the forehead, turning blackish-brown on the back of the ears. There is little variation in facial markings, with the muzzle being black, gradually shading into brown on the cheeks and forehead. Much of the species' coat patterning occurs on the trunk and legs. ![]() Colour variation is extreme, and may serve in visual identification, as African wild dogs can recognise each other at distances of 50–100 metres. There is some geographic variation in coat colour, with north-east African specimens tending to be predominantly black with small white and yellow patches, while southern African ones are more brightly coloured, sporting a mix of brown, black and white coats. It gradually loses its fur as it ages, with older specimens being almost naked. The fur of the African wild dog differs significantly from that of other canids, consisting entirely of stiff bristle-hairs with no underfur. This feature, termed "trenchant heel", is shared with two other canids: the Asian dhole and the South American bush dog. The skull is relatively shorter and broader than that of other canids. The heel of the lower carnassial M1 is crested with a single blade-like cusp, which enhances the shearing capacity of the teeth and thus the speed at which prey can be consumed. Its dentition also differs from that of Canis by the degeneration of the last lower molar, the narrowness of the canines, and proportionately large premolars, which are the largest relative to body size than any other carnivore other than hyenas. The middle two toepads are usually fused. Compared to members of the genus Canis, the African wild dog is comparatively lean and tall, with outsized ears and lacking dewclaws. The African wild dog is the bulkiest and most solidly built of African canids. The species stands 60–75 cm (24–30 in) in shoulder height, and weighs 20–25 kg (44–55 lb) in East Africa and up to 30 kg (66 lb) in southern Africa. Females are generally 3–7% smaller than males. Although not as prominent in African folklore or culture as other African carnivores, it has been respected in several hunter-gatherer societies, particularly those of the predynastic Egyptians and the San people. Like other canids, it regurgitates food for its young, but this action is also extended to adults, to the point of being the bedrock of African wild dog social life. It has few natural predators, though lions are a major source of mortality, and spotted hyenas are frequent kleptoparasites. The species is a specialised diurnal hunter of antelope, which it catches by chasing them to exhaustion. The African wild dog is a highly social animal, living in packs with separate dominance hierarchies for males and females. Uniquely among social carnivores, it is the females rather than the males that scatter from the natal pack once sexually mature, and the young are allowed to feed first on carcasses. The decline of these populations is ongoing, due to habitat fragmentation, human persecution, and disease outbreaks. The current population has been estimated at roughly 39 subpopulations containing 6,600 adults, only 1,400 of which are fully grown. It is classed as endangered by the IUCN, as it has disappeared from much of its original range. It is the largest of its family in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by its fewer toes and dentition, which is highly specialised for a hypercarnivorous diet. The African wild dog, African hunting dog, or African painted dog ( Lycaon pictus) is a canid native to Sub-Saharan Africa. ![]()
