Naming

The English language has several names for the African wild dog, including African hunting dog, Cape hunting dog, painted hunting dog, painted dog, and painted lycaon. One conservation organisation is promoting the name 'painted wolf' as a way of rebranding the species, as wild dog has several negative connotations that could be detrimental to its image. Nevertheless, the name "African wild dog" is still widely used, However, the name "painted dog" was found to be the most likely to counteract negative perceptions of the species.

. The skull is relatively shorter and broader than those of other canids. The fur of the African wild dog differs significantly from that of other canids, consisting entirely of stiff bristle-hairs with no underfur. It gradually loses its fur as it ages, with older individuals being almost naked. Colour variation is extreme, and may serve in visual identification, as African wild dogs can recognise each other at distances of . Some geographic variation is seen in coat colour, with northeastern 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. Much of the species' coat patterning occurs on the trunk and legs. Little variation in facial markings occurs, with the muzzle being black, gradually shading into brown on the cheeks and forehead. A black line extends up the forehead, turning blackish-brown on the back of the ears. A few specimens sport a brown teardrop-shaped mark below the eyes. The back of the head and neck are either brown or yellow. A white patch occasionally occurs behind the fore legs, with some specimens having completely white fore legs, chests and throats. The tail is usually white at the tip, black in the middle and brown at the base. Some specimens lack the white tip entirely, or may have black fur below the white tip. These coat patterns can be asymmetrical, with the left side of the body often having different markings from that of the right.

Males and females have separate dominance hierarchies, with the latter usually being led by the oldest female. Males may be led by the oldest male, but these can be supplanted by younger specimens; thus, some packs may contain elderly male former pack leaders. The dominant pair typically monopolises breeding. The species differs from most other social species in that males remain in the natal pack, while females disperse (a pattern also found in

es). Furthermore, males in any given pack tend to outnumber females 3:1. Dispersing females join other packs and evict some of the resident females related to the other pack members, thus preventing inbreeding and allowing the evicted individuals to find new packs of their own and breed. Males rarely disperse, and when they do, they are invariably rejected by other packs already containing males. Although arguably the most social canid, the species lacks the elaborate facial expressions and body language found in the gray wolf, likely because of the African wild dog's less hierarchical social structure. Furthermore, while elaborate facial expressions are important for wolves in re-establishing bonds after long periods of separation from their family groups, they are not as necessary to African wild dogs, which remain together for much longer periods. African wild dog populations in East Africa appear to have no fixed

lasts 69–73 days, with the interval between each pregnancy being 12–14 months typically. The African wild dog produces more pups than any other canid, with litters containing around six to 16 pups, with an average of 10, thus indicating that a single female can produce enough young to form a new pack every year. Because the amount of food necessary to feed more than two litters would be impossible to acquire by the average pack, breeding is strictly limited to the dominant female, which may kill the pups of subordinates. After giving birth, the mother stays close to the pups in the den, while the rest of the pack hunts. She typically drives away pack members approaching the pups until the latter are old enough to eat solid food at three to four weeks of age. The pups leave the den around the age of three weeks and are suckled outside. The pups are weaned at the age of five weeks, when they are fed regurgitated meat by the other pack members. By seven weeks, the pups begin to take on an adult appearance, with noticeable lengthening in the legs, muzzle, and ears. Once the pups reach the age of eight to 10 weeks, the pack abandons the den and the young follow the adults during hunts. The youngest pack members are permitted to eat first on kills, a privilege which ends once they become yearlings.


Ratio male/female

Packs of African wild dogs have a high ratio of males to females. This is a consequence of the males mostly staying with the pack whilst female offspring disperse and is supported by a changing sex-ratio in consecutive litters. Those born to maiden females contain a higher proportion of males, second litters are half and half and subsequent litters biased towards females with this trend increasing as females get older. As a result, the earlier litters provide stable hunters whilst the higher ratio of dispersals amongst the females stops a pack from getting too big.

s are characterized by a short, sharp exhale through the nostrils. When members of dominant mating pairs sneeze first, the group is much more likely to depart. If a dominant dog initiates, around three sneezes guarantee departure. When less dominant dogs sneeze first, if enough others also sneeze (about 10), then the group will go hunting. Researchers assert that wild dogs in Botswana, "use a specific vocalization (the sneeze) along with a variable quorum response mechanism in the decision-making process o go hunting at a particular moment.


Inbreeding avoidance

Because the African wild dog largely exists in fragmented, small populations, its existence is endangered. Inbreeding avoidance by mate selection is characteristic of the species and has important potential consequences for population persistence. Inbreeding is rare within natal packs. Inbreeding behavior may have been selected against evolutionarily because it leads to the expression of recessive deleterious alleles. Computer simulations indicate that all populations continuing to avoid incestuous mating will become extinct within 100 years due to the unavailability of unrelated mates. Thus, the impact of reduced numbers of suitable unrelated mates will likely have a severe demographic impact on the future viability of small wild dog populations.

s.. It and the cheetah are the only primarily diurnal African large predators. The African wild dog hunts by approaching prey silently, then chasing it in a pursuit clocking at up to for 10–60 minutes. The average chase covers some , during which the prey animal, if large, is repeatedly bitten on the legs, belly, and rump until it stops running, while smaller prey is simply pulled down and torn apart. African wild dogs adjust their hunting strategy to the particular prey species. They will rush at wildebeest to panic the herd and isolate a vulnerable individual, but pursue territorial antelope species (which defend themselves by running in wide circles) by cutting across the arc to foil their escape. Medium-sized prey is often killed in 2–5 minutes, whereas larger prey such as wildebeest may take half an hour to pull down. Male wild dogs usually perform the task of grabbing dangerous prey, such as

, by the nose. Hunting success varies with prey type, vegetation cover and pack size, but African wild dogs tend to be very successful: often more than 60% of their chases end in a kill, sometimes up to 90%. Despite their smaller size, they are much more consistently successful than lion (27–30%) and hyena (25–30%), but African wild dogs commonly lose their kills to these two large predators. An analysis of 1,119 chases by a pack of six Okavango wild dogs showed that most were short distance uncoordinated chases, and the ''individual'' kill rate was only 15.5 percent.

Unlike most social predators, African wild dogs will regurgitate food for other adults as well as young family members. Pups old enough to eat solid food are given first priority at kills, eating even before the dominant pair; subordinate adult dogs help feed and protect the pups.

during the 1960s resulted in an increase in African wild dog sightings, only for their numbers to decline once the lions recovered. As with other large predators killed by lion prides, the dogs are usually killed and left uneaten by the lions, indicating the competitive rather than predatory nature of the larger species' dominance. However, a few cases have been reported of old and wounded lions falling prey to African wild dogs.Schaller, G. B. (1972). ''The Serengeti lion: A study of predator-prey relations''. Chicago: University of Chicago Press. p. 188. . On occasion, packs of wild dogs have been observed defending pack members attacked by single lions, sometimes successfully. One pack in the Okavango in March 2016 was photographed by safari guides waging "an incredible fight" against a lioness that attacked a subadult dog at an impala kill, which forced the lioness to retreat, although the subadult dog died.

s are important kleptoparasites and follow packs of African wild dogs to appropriate their kills. They typically inspect areas where African wild dogs have rested and eat any food remains they find. When approaching African wild dogs at a kill, solitary hyenas approach cautiously and attempt to take off with a piece of meat unnoticed, though they may be mobbed in the attempt. When operating in groups, spotted hyenas are more successful in pirating African wild dog kills, though the latter's greater tendency to assist each other puts them at an advantage against spotted hyenas, which rarely work cooperatively. Cases of African wild dogs scavenging from spotted hyenas are rare. Although African wild dog packs can easily repel solitary hyenas, on the whole, the relationship between the two species is a one-sided benefit for the hyenas, with African wild dog densities being negatively correlated with high hyena populations. Beyond piracy, cases of interspecific killing of African wild dogs by spotted hyenas are documented. African wild dogs are
