Alano Español, sometimes called the Spanish Bulldog in English, is a very large breed of dog of the molosser dog type, originating in Spain. The breed is best known for its former use during Spanish bullfights.

Appearance

The Alano Español is a very large dog of the Molosser type, with a large, strong head. Males should be no smaller than 60 centimetres (24 in) at the withers, and should weigh 38–45 kilograms (84–99 lb) with females somewhat smaller.

The coat is short and thick, and is most often a brindle of any color, including red, bayo (a yellow bay), blue or grey. White patches are not typical. The face may or may not have a black mask.

The muzzle is short with the lower jaw slightly concave, and has a very large, broad, black nose. The ears are set high and may be drop or cut short. The skin is very thick, with neck folds and some wrinkles on the face.

History

The name of the breed comes from the Alani, nomadic pastoralists who arrived in Spain as part of the transhumance. These peoples were known to keep large livestock guardian dogs, later called the Alaunt. The first written reference to the type in Spain is in a chapter of the 14th century "Book of the Hunt of Alfonso XI" (Libro de la Montería de Alfonso XI) in which hunting dogs called Alani are described as having beautiful colours. Dogs of this type traveled with Spanish explorers and were used as war dogs in the subjugation of Indian (Native American) peoples, as well as in the capturing of slaves. A similar type dog was described in the Canary Islands, and can be seen on that archipelago's coat of arms.

Etching by Francisco de Goya portraying the dogs in the bullfighting ring as they were used in 1816. Note that the dog's ears are uncropped, indicating they were only used for bull baiting and not dog fighting.

Bull baiting done in the bullfighting ring with dogs of this type was recorded by Francisco de Goya in his series on La Tauromaquia in 1816. Besides their use as war dogs and use in the bullring, the large dogs were also used for hunting big game such as wild boar, and, as with bulldogs in other countries, as a butcher's dog.

The large dogs began to disappear as the work they did began to change. Big game became rare, stockyards were modernized and no longer used dogs to hold the cattle, use in bullfights was outlawed, and by 1963 Alanos were thought to be extinct. In the 1970s a group of fanciers and veterinary students made house-to house surveys in western and northern Spain, and found a few examples of the dogs in the Basque areas of Enkarterri and Cantabria, being used to herd semi-wild cattle and hunt wild boar. A standard was written and the dogs were documented and bred, and the Alano Español was recognised as a separate breed by the Spanish Kennel Club in 2004. The Spanish Ministry of Agriculture (Ministerio de Agricultura, Pesca y Alimentación) recognises the Alano Español as an indigenous Spanish breed.

Although the breed in Spain is still small in number and the breed has not yet been recognised internationally by the Fédération Cynologique Internationale, examples of the Alano Español have been exported to North America, where a few breeders are promoting it for the rare breed pet market.

Similar breeds

Large dogs that are similar in appearance and may share the history of the Alano Español include the molossers of the Canary Islands such as the Dogo Canario (Perro de Presa Canario) as well as the Mastín Español (Spanish Mastiff) and the White English Bulldog of La Florida (today's South of USA). The Cimarron Uruguayo is a South American breed that also looks somewhat similar, and is descended from the dogs of the Spanish explorers and conquistadores. The Alano Español's cropped ears, not seen in the Goya bullfighting picture from 1816, indicate that the breed is or has been used for dogfighting. The breed is also sometimes called the Spanish Bulldog in English. English dog dealer Bill George imported a dog he called "Big Headed Billy" in 1840. He was used to increase siee in English Bulldogs.

Health

The breed is too newly recognised to have a record of health issues. However, the restoration of the breed started with an extremely small number of animals, so problems associated with inbreeding may appear. All large dogs should be tested for hip dysplasia before being bred.

Temperament

Since the breed was used for hunting in packs, it is very sociable with other dogs. All large dogs must be well socialized with humans and other animals when young, if they are to be safely kept as pets. Large working dogs such as the Alano Español need regular training and activity all of their lives.

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.
