The Africanis is a group of South African dogs not recognized as a breed. It is believed to be of ancient origin, directly descended from hounds and pariah dogs of ancient Africa, introduced into the Nile Valley from the Levant. The Swahili name for the breed is umbwa wa ki-shenzi meaning common or mongrel or "traditional dog". Africanis is also an umbrella name for all the aboriginal dogs in southern Africa.

Appearance

The Africanis is a short-coated, medium-sized dog, well-muscled and slightly longer than tall. It can be of any colour and occasionally come with a ridgeback. The Africanis has over the years been shaped by Africa for Africa. Its beauty is embodied in the simplicity and functionality of its body. It is slenderly built, agile, supple, and capable of great speed.

Temperament

The Africanis is well disposed without being obtrusive: a friendly dog showing watchful territorial behaviour. The breed is independent and territorial, but highly trainable.

It is my experience that the Africanis is a marvellous pet and house dog. Guided by its instinct of subservience it will steal your heart before you realise it.

- Johan Gallant, President of the Africanis Society of Southern Africa (September 9, 2005).

Health

The Africanis needs neither pampering nor special food. It is consistently healthy and has, over the years, developed a natural resistance against internal and external parasites.

History

There is ample evidence that no canine domestication took place in Africa and that the traditional African dog is a descendant of dogs that had been domesticated in the East and came to Africa. Their earliest presence has been established in Egypt and dated at 4700 BC. Archaeological records show that, from then on, the dog spread rapidly along the Nile into Sudan and even beyond. At the same time, migrations, trade, and transhumance took it deep into the Sahara. By 2000 BC, this moving frontier stopped for a long period. Meanwhile, throughout the Egyptian dynasties, the breeding of swift and slender hounds together with a variety of common dogs became very popular.
For thousands of years, the aboriginal Stone Age San (Bushman) populations in Southern Africa hunted without the help of dogs. Although the Khoikhoi brought domestic sheep along a western migratory route to the Cape of Good Hope just before the Christian era, there is no conclusive evidence that dogs were part of their party.The domestic dog first arrived in Southern Africa with the migration of the Early Iron Age Bantu speaking people. Dogs of Nilotic origin consecutively joined the Early and also Later Iron Age migrations. It is generally accepted that these migrations travelled along the Central Rift and the Lacustrine region. They followed tsetse-free corridors through Zambia and Zimbabwe to reach Botswana and finally South Africa. The earliest evidence for the presence of a domestic dog in South Africa has been established by Dr. Ina Plug, deputy director of the Transvaal Museum. The remains were found near the Botswana border and dated at 570 AD. By 650 AD the presence of the house dog is established in the Lower Thukela valley. By 800 AD it is part of a Khoisan settlement in Cape St. Francis, indicating that contact and trade between Bantu and Khoisan had been established.

For hundreds of years this exclusive primitive canine gene pool adapted to various conditions of the Southern African landscape and, through natural selection, evolved into ecotypes all belonging to the same landrace. It is sometimes argued that dogs brought by the Arab trade, Eastern seafarers, and Portuguese explorers might, over the years, have "contaminated" the traditional African dog. In other opinions, these chances are scant. Exotic canine influences became more likely after the colonisation of Transkei and Zululand during the 19th century.

The true Africanis is still found today in tribal areas where people maintain their traditional lifestyle. The fast-changing South Africa and the impact that this causes on rural societies, together with a certain disdain for the traditional dog and the status that the ownership of an exotic breed provides, poses an increasing threat to the continuation of the aboriginal Africanis. The Africanis Society of Southern Africa was founded to conserve this ancient gene pool. Conserving the Africanis as a land race stands for conserving biodiversity.

Today, the Africanis is recognized by the Kennel Union of Southern Africa (KUSA) as an emerging breed.

Breeding / Reproduction

In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles biannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation. Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male.

Dogs bear their litters roughly 56 to 72 days after fertilization, with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. Toy dogs generally produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.

Some dog breeds have acquired traits through selective breeding that interfere with reproduction. Male French Bulldogs, for instance, are incapable of mounting the female. For many dogs of this breed, the female must be artificially inseminated in order to reproduce

Neutering

Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.

According to the Humane Society of the United States, 3–4 million dogs and cats are put down each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down. Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from shelters instead of purchasing them.


Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either gender.

Dog Communication

Dog communication refers to body movements and sounds dogs use to send signals to other dogs, and other animals (usually humans). Dog communication comes in a variety of forms, and is part of the foundation of dog social behavior (see Dog Society). Dogs use certain movements of their bodies and body parts and different vocalizations to send signals. There are a number of basic ways a dog can communicate. These are movements of the ears, eyes, eyebrows, mouth, head, tail, and entire body, as well as barks, growls, whines and whimpers, and howls.

It is important to note that while many gestures and actions have common, stereotypical meanings, researchers regularly seem to find that animal communication is often more complex and subtle than previously believed, and that the same gesture may have multiple distinct meanings depending on context and other behaviors. So, generalizations such as "X means Y" are often, but not always accurate. For example, even a simple tail wag may (depending on context) convey many meanings including:

• Excitement

• Anticipation

• Playfulness

• Contentment/enjoyment

• Happy, self-confidence

But also:

• Anxiety

• Questioning another animal or a human as to intentions

• Tentative role assessment on meeting another animal

• Reassurance ("I'm friendly, are you?")

• Reconciliation (after an aggressive interaction: "I still want to be friends")

• Uncertainty/apprehension

• Submissive placation

Combined with other body language, in a specific context, many gestures such as yawns and direction of vision all convey meaning. Panting may mean "Too hot"; it might also mean either emotional anxiety or happiness. Thus statements that a particular action "means" something should always be interpreted to mean "often means" something. As with human beings, who may smile or hug or stand a particular way for multiple reasons, many animals reuse gestures too.

Health risks to humans

In the USA, dogs cause 88% of the 86,000 falls caused by pets. Dog feces can cause a number of human diseases, including toxocariasis, which can cause blindness, and can also cause human hookworm. In the United States, about 10,000 cases of Toxocara infection are reported in humans each year. Almost 14% of the US population is infected with Toxocara, a parasite of dogs and cats that can be passed from animals to humans.

The incidence of dog bites, and especially fatal dog bites, is extremely rare in America considering the number of pet dogs in the country. Fatalities from dog bites occur in America at the rate of one per four million dogs. A Colorado study found that bites in children were less severe than bites in adults. The incidence of dog bites in the US is 12.9 per 10,000 inhabitants, but for boys aged 5 to 9 the incidence rate is 60.7 per 10,000. Moreover, children have a much higher chance to be bitten in the face or neck. Sharp claws with powerful muscles behind them can lacerate flesh in a scratch that can lead to serious infections.

In the UK between 2003 and 2004, there were 5,868 dog attacks on humans resulting in 5,770 working days lost in sick leave.
