What methods do African wild dogs use to hunt their prey?

African wild dogs are among the most efficient hunters in Africa. It is when they hunt that the important role of the pack becomes very clear.

They hunt by day, usually in the early morning or evening and occasionally in the moonlight.

They rely on their phenomenal stamina to tire their prey and the combined strength of the pack to bring the prey down.

Often they make no attempt at concealment and approach potential prey openly at a slow trot while they will keep their heads low and ears back. They will break into a run only when the prey flees.

They may rush a herd into flight and then stand watching to identify potential members of the herd that is slower than the rest.

The leading dog, which is usually the dominant male or female will selects a particular target and pursues it in a very single-minded manner. The rest of the pack will follow in lines behind the leader.

It can happen that one of the other dogs chooses a different prey and so lead some of the dogs on another chase. In this case the pack splits up and multiple kills may be made.

Wild dogs can reach speeds of 60 kilometers per hour during the chase. This is too slow to catch a medium-sized antelope during a short sprint chase. Instead they depend on their stamina in long pursuits to wear down the prey.

Most chases cover 3-5 km pursuits to wear down the prey.



As soon as the dog catches up with the prey it will pull it down if it is small enough. In the case of larger prey, it will run alongside and slash at its rump to slow it down until more dogs catch up.

The dogs then bite chunks out of the prey and disembowel it so that it dies of shock and loss of blood.

Statistics indicate that the prey has only ten to thirty percent chances of escaping from African wild dog hunting expeditions.

This compares to a six to eight in ten chance of evading an attack by lions or hyenas.

In the Kruger National Park the wild dogs have no specialized techniques for dealing with large and dangerous prey and both wildebeest and zebras will stand their ground when stalked by the dogs.

What prey do African wild dogs like to hunt?

African wild dogs play an important role in eliminating sick and weak animals amongst their target prey species.

They are specialized hunters of medium sized antelope in the 15-50 kilogram range like springbok and impala.

They will also take animals such as small as hares and occasionally warthogs and foxes. They very rarely scavenge.


Statistics indicate that kills in the Kruger National Park consists of 8% Kudu, 75% impala and 15% smaller antelope.

In Southern Africa they do not hunt adult wildebeest and zebra. In Hwange National Park their diet consists of 54% impala and 23% kudu.

What social structure do African wild dogs display?

An African Wild dog pack can consist of anything from two to over fifty dogs, but most of them have about between 12 to 20 adult members.

Each pack occupies enormous home ranges. This stretches to about 450 square kilometers in the Kruger National Park and in East Africa up to 4 000 square kilometers. As long as the puppies are too young to travel a pack will operate from a fixed base.

A dominant male and female known as the alpha pair will head the pack. This pair will in the vast majority of cases, account for all the breeding activity.

All pack members will help raise the pups. The rest of the pack will consist of the offspring of the current or previous alpha pair.

Wild dogs are unusual in that it is the females who leave their birth pack at 14–30 months of age and join other packs that lack sexually mature females. The males remain in their pack to become helpers.

This is unusual because the opposite is usually true with social mammals, where a group of related females usually forms the core of the social group.

Below the alpha pair there is no definite hierarchy. Submissiveness and not aggression, is the deciding factor during wild dog social interactions.

A typical example of this is displayed when a dog who wants a piece of meat after a hunt. The dog will beg for some meat with head and forequarters flat to the ground, hindquarters raised, ears flattened to its head and lips drawn back.

Feeding time displays a strong sense of sharing

Speed is of the essence when they feed to avoid the kill being stolen. They sometimes face intense competition from spotted hyenas that will team up with one another to pusg the dogs aside.

A pack of wild dogs is usually able to keep hyenas at bay because some of the dogs concentrate on guard duty while the others feed. The larger the pack of dogs, the better their chances of keeping spotted hyenas at bay.

They do not fight with each other like lion and hyena does during feeding. They can eat 100 kilogram of meat from an adult kudu in 15 minutes.

A very important part of the wild dog hunting and feeding behavior is the division of the spoils after a successful hunt.

Some dogs do not participate in the hunt because they remain behind at the den to guard puppies.

When the pack returns from the hunt, these dogs will beg food from other members. It does this by grinning, nudging and nibbling their lips, licking their faces, lowering its forequarters and raising its tail.

Puppies will usually be fed first. Sick and injured African wild dogs also receive a share of meat for as long as they remain with the pack.

How do African wild dogs communicate with each other?

Intense social interactions, mostly involving sniffing and muzzle licking bond African wild dog packs.

When they are excited, such as before a hunt or just after a kill they will give a high-pitched twitter.

Their long-range contact call is a musical hoooo that carries for 2 to 3 km. They also whine when begging and their alarm call is a deep bark.

Urine scent marks are used to show that an area is occupied and by the dominant female to advertise that she is sexually receptive.

The dominant male immediately urinates on top of her scent marks, to deter competitors.

These African animals have a very strong body odor. Dogs separated from the pack track their way back to it by smell.

African wild dogs also communicate by body posture and tail position. tail tucked between the legs signals fear and submissiveness.

A friendly dog has an upright posture and it curls its tail up over its back. An aggressive dog will be rigidly upright. Adults as well as pups play.

How do African wild dogs breed ?

Typically only one pair in the pack breeds. Very rarely will a second female give birth and if this happens the dominant female may kidnap and raise her young ( in extreme cases she will even kill these pups).

This is done to maintain an optimum pack size

Wild dog mothers have their pups in underground holes like old aardvark diggings. Males will stay in the pack and help raise subsequent litters.

The pups begin to wean at only two weeks of age. The whole pack regurgitates meat for them will contribute to raising them if the mother should die.
