african wild dog

Lycaon pictus is a large canid found only in Africa, especially in savannas and other lightly wooded areas. It is commonly called the African Hunting Dog, African Wild Dog, Painted Wolf, Cape Hunting Dog, Painted Dog, Painted Hunting Dog, Spotted Dog or Ornate Wolf.
The scientific name "Lycaon pictus" is derived from the Greek for "wolf" and the Latin for "painted". It is the only canid species to lack dewclaws on the forelimbs.

Adults typically weigh 18–34 kilograms (40–75 lb).[2] A tall, lean animal, it stands about 75 centimetres (30 in) at the shoulder, with a head and body length averaging about 100 centimetres (39 in) long with a tail of 30 to 45 centimetres (12 to 18 in). Animals in southern Africa are generally larger than those in eastern or western Africa.

There is little sexual dimorphism, though judging by skeletal dimensions, males are usually 3-7% larger. It has a dental formula offor a total of 42 teeth. The premolars are relatively large compared with those of other canids, allowing it to consume a large quantity of bone, much like hyenas.[3] The heel of the lower carnassial M1 is crested with a single cusp, which enhances the shearing capacity of teeth and thus the speed at which prey can be consumed. This feature is called trenchant heel and is shared with two other canids: the Asian Dhole and the South American Bush Dog.

A study established that the African Wild Dog had a Bite Force Quotient of 142, the highest of any extant mammal of the order Carnivora.[4] The BFQ is essentially the strength of bite as measured against the animal's mass.

The African Wild Dog reproduces at any time of year, although mating peaks between March and June during the second half of the rainy season. Litters can contain 2-19 pups, though 10 is the most usual number.[5] The time between births is usually 12–14 months, though it can also be as short as 6 months if all of the previous young die. The typical gestation period is approximately 70 days.[6][not in citation given] Pups are usually born in an abandoned den dug by other animals such as those of the Aardvark. Weaning takes place at about 10 weeks. After 3 months, the den is abandoned and the pups begin to run with the pack. At the age of 8–11 months they can kill small prey, but they are not proficient until about 12–14 months, at which time they can fend for themselves. Pups reach sexual maturity at the age of 12–18 months.
