Dingo

Dingoes, though generally associated with Australia, likely originated from Southeast Asia and were introduced to Australia about 3,000 years ago.

The dingo is legendary as Australia's wild dog, though it also occurs in Southeast Asia. The Australian animals may be descendents of Asian dingoes that were introduced to the continent some 3,000 to 4,000 years ago.

These golden or reddish-colored canids may live alone (especially young males) or in packs of up to ten animals. They roam great distances and communicate with wolf-like howls.

Dingo hunting is opportunistic. Animals hunt alone or in cooperative packs. They pursue small game such as rabbits, rodents, birds, and lizards. These dogs will eat fruits and plants as well. They also scavenge from humans, particularly in their Asian range.

Dingoes breed only once a year. Females typically give birth to about five pups, which are not independent until six to eight months of age. In packs, a dominant breeding female will kill the offspring of other females.

Australia is home to so many of these animals that they are generally considered pests. A famous "dingo fence" has been erected to protect grazing lands for the continent's herds of sheep. It is likely that more dingoes live in Australia today than when Europeans first arrived.

Though dingoes are numerous, their pure genetic strain is gradually being compromised. They can and do interbreed with domestic dogs to produce hybrid animals. Studies suggest that more than a third of southeastern Australia's dingoes are hybrids.

Domestic Dog

Dogs were probably the first tame animals. They have accompanied humans for some 10,000 years. Some scientists assert that all dogs, domestic and wild, share a common ancestor in the small South Asian wolf.

Today humans have bred hundreds of different domestic dog breeds—some of which could never survive in the wild. Despite their many shapes and sizes all domestic dogs, from Newfoundlands to pugs, are members of the same species—Canis familiaris. Although they have domestic temperaments, these dogs are related to wolves, foxes, and jackals.

Domestic dogs still share many behaviors with their wild relatives. Both defend their territories and mark them by urinating on trees, rocks, fence posts, and other suitable sites. These scent posts serve notice to other dogs that an animal is occupying its territory.

Many pet dogs also bury bones or favorite toys for future use, just as their wild relatives sometimes bury a kill to secure the meat for later feasts.

Dogs communicate in several ways. Scent is one method, another is physical appearance. Body position, movement, and facial expression often convey a strong message. Many of these signals are recognizable even to humans, such as the excited tail-wagging of a happy dog or the bared teeth of an angry or threatened animal. Vocally, dogs communicate with a cacophony of sounds including barks, growls, and whines.

Domestic dogs serve as more than companions; many earn their keep by working hard. Dogs herd livestock, aid hunters, guard homes, and perform police and rescue work. Some special animals even guide the blind—a poignant symbol of the dog's longstanding role as man's best friend.

African Wild Dog

The African wild dog, also called Cape hunting dog or painted dog, typically roams the open plains and sparse woodlands of sub-Saharan Africa.

These long-legged canines have only four toes per foot, unlike other dogs, which have five toes on their forefeet. The dog's Latin name means "painted wolf," referring to the animal's irregular, mottled coat, which features patches of red, black, brown, white, and yellow fur. Each animal has its own unique coat pattern, and all have big, rounded ears.

Packs and Hunting

African wild dogs live in packs that are usually dominated by a monogamous breeding pair. The female has a litter of 2 to 20 pups, which are cared for by the entire pack. These dogs are very social, and packs have been known to share food and to assist weak or ill members. Social interactions are common, and the dogs communicate by touch, actions, and vocalizations.

African wild dogs hunt in formidable, cooperative packs of 6 to 20 (or more) animals. Larger packs were more common before the dogs became endangered. Packs hunt antelopes and will also tackle much larger prey, such as wildebeests, particularly if their quarry is ill or injured. The dogs supplement their diet with rodents and birds. As human settlements expand, the dogs have sometimes developed a taste for livestock, though significant damage is rare. Unfortunately, they are often hunted and killed by farmers who fear for their domestic animals.

African hunting dogs are endangered. They are faced with shrinking room to roam in their African home. They are also quite susceptible to diseases spread by domestic animals.
