A number of modern breeds are believed directly descended from the Alaunt. The original alaunt is thought to have resembled a Caucasian Ovcharka. They were large, short coated mountain dogs of varying type. The Alaunt was bred and formed by the Alani tribes, the nomads of Indo-European Sarmatian ancestry who were related to the Sarmatians and spoke an Indo-Iranian language. The Alans were known as superb warriors, herdsmen, and breeders of horses and dogs. The Alans bred their dogs for work and had developed different strains within the breed for specific duties.

History

As far as is known, the Alaunt's primary ancestors were working dogs such as the Armenian Gampr and the Sarmatian Mastiff from the Caucasus and the Alabai from Central Asia, but also the shorthaired hounds of India and Persia. However, the Ayran Flock Guardian or Sage Koochi steppe type that decends from the steppes of Asia, brought by the steppe nomads, used to domesticate the horse, control and defend large livestock far predates these breeds in working type, giving the genetic template of the Alaunt. The steppe nomads taught the Assyrains of the use of the horse and chariot.

In the 370s, Hun invasions divided the Alani into the Eastern and Western Alans. The Eastern Alani tribes merged with the Ossetians and other nations, introducing their dogs into the bloodlines of many Balkan breeds, such as the Illyrian Mountain Dog, Metchkar, Qen Ghedje, Hellenikos Poimenikos and other Molossers of the region. Some believe that the white-coloured Alaunts were the direct ancestors of Greek and Albanian breeds, which in turn influenced all other white dogs in the Balkans. The Western Alans joined the Vandals on their raids through Europe and by the 410s, their fierce dogs were influencing many breeds in France, Spain, Portugal, England and other countries, spreading the use of the "alaunt" name, which became synonymous with a type of a working dog, rather than a specific breed. Through breeding with various scenthounds and sighthounds, the Alaunt became a valued large game hunting dog, existing in a variety of types, dictated by regional preferences. In 1500, Spain was known for breeding the best Alaunts and used them to conquer the New World.

In France, Alaunts were separated into three main categories, based on physical appearance and the duties they performed. The lightest type was the Alaunt Gentil, a greyhound-like dog, which eventually became assimilated into the local hunting breeds with the Alaunt Veantre. The heavier mastiff variety, known as the Alaunt de Boucherie, was crucial in the development of the fighting and baiting dogs of France. The Alaunt de Boucherie in France was known as the Alaunt Butchers in England and were termed the original Bulldogs as they were used to control and defend herds of cattle. The process was repeated in other countries, such as England which already had very large Mastiffs which were crossed with the Alaunt and Terriers to create the baiting bulldog. Only two known renmants of true ancient Alaunt type still exist worldwide: The Alano of Northern Spain and the White English Bulldog of USA. The Alaunt was known as the Bullenbeisser (German for Bull Biter)in Germany which was crossed with white bulldogs from England to create the Boxer and is the origins of the Great Dane.

Modern relatives

Contemporary enthusiasts are developing new breeds based on Alaunt bloodlines, such as the New Alaunt, Antebellum_Bulldog or Altamaha Plantation Dog, Dogo Belgrado, Abraxas bulldog and the American Alaunt. While its origins are strongly rooted in the ancient mountain dogs of the East, the Alaunt is regarded by some cynologists as the ancestor the original bulldog breeds.

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.
