The Chihuahua was discovered and domesticated from its wild state in the Mexican state of Chihuahua, hence its name. The Chihuahua is the smallest breed dog in the world, although many believe it is Yorkshire. It is a very funny race although a little nerdy. At the time of the Aztecs this dog was considered sacred and it was believed that it brought joy and happiness in the houses, for that reason it was revered by the Aztecs as a divinity. The Chihuaha was taken to the USA by the hand of American visitors who visited Mexico and once in the USA were presented at canófilas fairs, through which they were made known worldwide.
The Chihuahuas are known for their small size and long, straight ears. A Chihuahua is a dog with a compact body, its head is of a tapered shape and its tail is moderately long, held in a high arched or semicircle, with the tip directed towards the back. It has a well-rounded skull, with a well-defined nasal fronto, sunken and wide. His nose is moderately short and slightly upturned. The eyes are large and round and very expressive, the ears are large, erect, unfolded and widely open being wide at the base. The neck is slightly arched and of medium length. Its body is compact, short, firm and well structured. It has a long tail, wide at its base that gradually reduces towards the tip. Its legs are small and oval, its fingers are separated. The coat of this type of dog can be short and soft, long and straight or barely wavy, with curled collar and plumed tail.
They are intelligent dogs, of great vitality and energy, although the main characteristic of the behavior of this breed is the affection that they vindicate their owners. At the same time, they are distrustful of strangers who arrive in their territory. When they get scared they can get to bite and it also stands out for its sharp barking. Their alertness, intelligence and size make them adaptable to a variety of environments, including the city and small houses. Normally they usually live about fifteen years or more. You should bear in mind that many Chihuahuas are sensitive to cold, due to their small body size.
The Chihuahas are omnivores and you must pay special attention to give them a balanced and adequate nutrition, without overfeeding them, because overweight Chihuahuas tend to have problems in ligaments, chronic bronchitis and a shortening of life. Their hair, if short, can be brushed once a week, but if you have long hair you should brush daily with a soft brush. In both cases you should bathe once a month with warm water and shampoo.
The Chihuahua requires the attention of a veterinarian in situations such as birth and dental care. Chihuahas can present neurological genetic abnormalities such as strokes or epilepsy. They can also present knee dislocation (a very common ailment in such small breeds). Another genetic anomaly in the Chihuahas is hydrocephalus or water in the brain. It usually occurs in young puppies and usually ends with the puppy's death before six months of age. This disease is due to the puppy having an abnormally large head during its first months of life. Some symptoms of hydrocephalus are when the puppy has a patchy patch of plaque instead of solid bone, and usually does not grow at the same rate as the others. A veterinarian can easily diagnose a case of hydrocephalus.
