The African wild dog (Lycaon pictus), also known as the painted dog or Cape hunting dog, is a highly specialised hunter of terrestrial ungulates. It is the largest wild canine in Africa, and its diet consists of mostly medium-sized antelopes, including impala, greater kudu, springbok, and Thomson's gazelles. Impala makes up the majority of their diet, but this can vary depending on their habitat. African wild dogs are carnivores with short digestive tracts, high hydrochloric stomach acid, and a diet high in protein and fat. They live in packs of around 7 to 15 members and defend their territories against intruders. Human settlements and agriculture have impacted their hunting habits, leading to conflicts with farmers and retaliation killings.

What You'll Learn
African wild dogs are obligate carnivores
African wild dogs, or Lycaon pictus, are obligate carnivores. This means that their diet consists of meat exclusively. They are native to sub-Saharan Africa and are the largest wild canine on the continent. With their hypercarnivorous diet, they are distinguished from Canis by dentition, or teeth designed for eating meat, and by a lack of dewclaws.
African wild dogs have the most specialised adaptations among the canids for their diet. Their teeth are generally carnassial-shaped, and their premolars are the largest relative to their body size of any living carnivoran, except for the spotted hyena. The lower carnassials, or first lower molars, have evolved into cutting blades for slicing flesh, and they have a reduced number or absence of post-carnassial molars. These adaptations are also found in two other hypercarnivorous canids: the dhole and the bush dog.
African wild dogs are highly collaborative hunters, working together in packs of 3 to 20 individuals to pursue their prey. They are known for their endurance, chasing their prey at speeds of up to 60-70 km/h over distances of 4-5 km. They typically hunt at dawn and dusk and consume small (<25 kg) to medium-sized (40-90 kg) prey, such as Red duiker and Bushbuck. Impala and Nyala make up a significant portion of their diet, and they usually kill between 1-4 animals per day.
In captivity, such as in zoos, African wild dogs are fed a nutritionally complete, raw meat-based diet. They are typically given 1-1.36 kg of meat per animal daily, along with various supplements like beef, horse, or oxtail bones, and occasional whole carcasses like chicks, rabbits, rats, and mice.
African wild dogs have a rapid digestive system that caters to their high-energy demands and rapid metabolic rate. Their digestive tracts are relatively short, consisting of a monogastric (single-chambered) stomach, a short hindgut, a small colon, and a caecum. High hydrochloric stomach acid ensures quick digestion of protein and fat.

They hunt in packs
African wild dogs are obligate carnivores, with a diet consisting of meat and small to medium-sized prey. They hunt in packs, typically consisting of 3 to 20 individuals, with an average of 9 to 10 adults plus juveniles. Packs are made up of relatives, with both males and females leaving the pack they were born in, and travelling to new territories. The males tend to disperse later than the females, and travel further. The females in a pack are closely related, as are the males, but the males and females within a pack are not related to each other.
The packs are highly social and collaborative, with all members working together to rear pups born to the dominant male and female. They are also flexible and adaptable in their hunting strategies, with individuals splitting from the pack and killing whatever they can, sometimes with help from another pack. They eat together, quickly and quietly, and share the food. If pups are travelling with the pack, they get to eat first. If they remain in the den, the adults will regurgitate meat for them when they return.
African wild dogs are highly successful hunters, with the stamina to pursue their prey across vast distances at speeds of up to 60-70km/hr. They typically hunt at dawn and dusk, but also display diurnal activity. They are the largest wild canine in Africa, with the most specialised adaptations among the canids for coat colour and diet. Their teeth are designed for eating meat, with large premolars relative to their body size, and lower carnassials that act as cutting blades for slicing flesh.
The pack's hunting strategy is an important part of their social unit, with the dominant pair marking their territory with faeces and urine. Their complex communication system includes vocalisations and scent marking, with high-frequency sounds used to communicate quietly when hunting.

Their diet in captivity
African wild dogs are obligate carnivores, meaning they are purely carnivorous and their diet consists of meat. They are expert hunters, with dagger-like teeth designed for eating meat. They are the largest wild canine in Africa and possess the most specialised adaptations among the canids for their diet and hunting. They are known to prefer wildebeest and medium-sized antelopes, including impala, greater kudu, springbok, and Thomson's gazelles. However, their diet can vary depending on their location; for example, in Samburu and Laikipia, Kenya, dik-diks account for 70% of their diet.
In captivity, the diet of African wild dogs should remain consistent throughout the year, similar to their diet in the wild, which does not change significantly with the seasons. Captive African wild dogs do not hunt to the same extent as their wild counterparts and spend less energy searching for food. A recommended diet for captive African wild dogs is a meat-based feline diet, supplemented with dry dog kibble fed twice daily and small carcasses or animal bones provided weekly. This captive diet ensures they receive the necessary nutrition without requiring the same level of physical activity as in the wild.
The pack dynamics of African wild dogs also influence their feeding behaviour. They typically live in packs of 3 to 20 individuals and hunt together to provide food for the entire group. The adults regurgitate their food for the pups, an essential survival strategy for the young dogs. This behaviour is common in captive and wild populations, ensuring the pups' nutritional needs are met and allowing the adults to teach the pups what types of food to eat.
African wild dogs have a rapid digestive system that caters to their high-energy demands and rapid metabolic rate. They have a complex communication system that includes vocalisations and scent marking, which they use to defend their territory against intruders. Their hunting strategy involves using stamina and cooperative hunting to exhaust their prey.

They are successful hunters
African wild dogs are expert hunters, with a diet consisting of mostly medium-sized antelopes, including impala, greater kudu, springbok, and Thomson's gazelles. They are the largest wild canines in Africa and possess several adaptations that make them highly successful in hunting their prey.
One of the key factors contributing to their hunting prowess is their highly specialized diet and physical adaptations. African wild dogs have dentition that is highly specialized for a hypercarnivorous diet, with a short digestive tract that facilitates the quick digestion of protein and fat. Their stomach contains high levels of hydrochloric acid, which aids in breaking down and absorbing their prey efficiently. Additionally, their graceful skeleton and extended stride resulting from the loss of the first digit on their forefeet, enhance their speed and agility in pursuit of their prey.
African wild dogs are known for their cooperative hunting strategies, working together in packs to flush, chase, and catch their prey. They typically live in packs ranging from seven to 15 members, with some packs reaching up to 40 individuals. This pack mentality allows them to take down larger prey, such as wildebeest, and defend their territory against intruders. The dogs will aggressively defend their territory, which can range from 234 square miles (606 km2), by fighting intruders to the death.
Their hunting success is also attributed to their energetic nature and endurance. African wild dogs primarily hunt at dawn and dusk, displaying diurnal activity patterns. They are known to cover vast amounts of land in their pursuit of food, expending significant energy in the process. This high-energy lifestyle is a crucial aspect of their survival strategy, as they require frequent replenishment of their energy reserves to maintain their active lifestyle.
African wild dogs play an important ecological role in controlling the population of prey species and preventing habitat destruction and overfeeding. Their hunting skills contribute to the maintenance of a balanced ecosystem. However, human settlements, farms, and grazing land have impacted their hunting habits, leading to conflicts with farmers over livestock and subsequent retaliation against the wild dogs.

Their digestive system
African wild dogs are obligate carnivores, with a monogastric digestive system that allows for the quick and efficient digestion of meat. This rapid digestive system suits their carnivorous diet and provides them with the nutrients they need to support their hunting lifestyle and survive in the wild.
The African wild dog's digestive system is well-adapted to break down and absorb nutrients from meat. They have sharp, large premolars relative to their body mass, which enable them to consume large quantities of meat and bone with remarkable speed. The teeth are designed for tearing and shredding meat, and their strong jaw muscles help to further break down the food into smaller pieces.
Once the food is in the stomach, it is mixed with powerful digestive juices and acids, which quickly break down proteins, fats, and carbohydrates. This rapid digestion is facilitated by high levels of hydrochloric stomach acid. The partially digested food then moves into the small intestine, where nutrients are absorbed into the bloodstream and transported to the body's cells.
African wild dogs have a relatively short digestive tract, consisting of a single-chambered stomach, a short hindgut, a small colon, and a caecum. They lack a large intestine as their diet does not require further breakdown by gut bacteria or fermentation. This short digestive tract is typical of carnivores and is in contrast to the multi-chambered stomachs of herbivores, which are designed to extract as many nutrients as possible from plant material.
The African wild dog's digestive system also allows for regurgitation, which is an important part of their feeding behaviour. Adults will regurgitate food for their young, but also for other adults within the pack as a means of social bonding. This behaviour ensures that the pack remains well-fed and strengthens the social unit.
