México FCI 263

The Chihuahueno It originates in Mexico and receives its name from the Mexican State of Chihuahua, place where it was discovered and domesticated from the wild, In contrast to the belief that exists in some countries that the dog gave the name to the State already that the word “Chihuahua” means “arid and sandy” in rarámuri, language of the Tarahumara people. Although it is known as Chihuahua, the official name of the breed is Chihuahua, Chihuahua is the name adopted in United States for the race.

It is believed that they are descended from a race of ancient Hispaniola island, similar but slightly larger, associated with royalty in the Toltec civilization known as the Techichi (found remains of smaller dogs in ancient tombs at Mexico.

Chihuahuas were brought to United States by American visitors who visited the North of Mexico and, later, presented at trade fairs Canófilas where they became known to worldwide.

The history of the race is uncertain, However usually say that it is a breed of Mexico. Are notions of the beginning of the race in several engravings of the Mesoamerican cultures of Mexico, from the North of the country through downtown to Yucatán (South). Plying the Toltec cultures, Aztecs, Teotihuacans and Maya.

Another theory says that they inhabited the continent because they were brought by the first settlers who passed through the Bering Strait (unproven theory), or that they were brought to Mexico by the Spaniards at the time of the colony from China. Another theory says that the Chihuahua is the result of the intersection of other ancient races that inhabited the ancient Mexico.

One of the first theories was simply living in the wild in the Mexican State of Chihuahua and that they were domesticated by the people of the region until you reach virtually all pre-Columbian Mexico by trade. These dogs came to embark in countries such as: United States, Costa Rica, Cuba, most Hispanic countries and Spain.

But among so much theory, something we can be sure, Chihuahuas are well known for its small size and its long, straight ears.

The AKC (American Kennel Club) recognizes two varieties of Chihuahuas: long hair and short hair. Many short haired Chihuahuas have very fine hair, but others have a very dense and thick hair. Standards of breeding this dog not generally specify a height, only a weight and a description of its overall proportions. As a result, the height varies more than in any other race.

Generally, the height range is between 15 and 25 cm to the cross. However, some dogs grow up the 30 - 38 cm.. AKC show dogs should weigh no more than 2,7 kg; the FCI standards mark dogs must weigh between 1,5 and 3 kg, Although most small dogs are acceptable in the show.

However, quality pet Chihuahuas (that is, those bred or purchased as companions rather than show dogs) can, and they achieve greater weight, until 4,5 kg or more if they have a skeletal structure that allows them to being overweight. This does not mean that they are not purebred Chihuahuas, It only means that the requirements do not have to enter a display.

Chihuahuas puppies that show Hydrocephalus have patched plates instead of solid bone skulls, they are typically lethargic and do not grow at the same pace as his brothers. A true case of Hydrocephalus can be diagnosed by a veterinarian, Although the prognosis is grim.

However some Chihuahuas can have what is called 'fontanel or Fontanelle', and it is completely natural and accepted for race, which is a small hole in the head where they do not have bone, only skin and hair. The Chihuahua is the only breed of dog that was born with an incomplete skull. Fontanel closes with age, but it requires great care during the first six months until the skull is fully formed.
