The Chihuahua (;[ane] Spanish: chihuahueño) is ane of the smallest breeds of dog,[2] and is named later on the Mexican land of Chihuahua.

History [edit]

Chihuahuas remained a rarity until the early 20th century, and the American Kennel Club did non register a Chihuahua until 1904.[3] In a 1520 letter, Hernan Cortés wrote that the Aztecs raised and sold the piffling dogs as food.[four] Colonial records refer to small, nearly hairless dogs at the beginning of the 19th century, 1 of which claims 16th-century conquistadores found them plentiful in the region afterward known as Chihuahua.[five]

Genetic lineage [edit]

An analysis of DNA from the genome of domesticated dogs indicates that they entered North America from Siberia for 4,500 years and were then isolated for the next 9,000 years. After contact with Europeans, these lineages were replaced by Eurasian dogs and their local descendants. The pre-contact dogs exhibited a unique genetic signature that is now almost gone.[six] In 2020, the sequencing of aboriginal domestic dog genomes indicates that in two Mexican breeds the Chihuahua retains 4% and the Xoloitzcuintli 3% pre-colonial ancestry.[7]

Appearance [edit]

Chihuahuas are the smallest brood recognized past some kennel clubs.[8]

Current brood standards defined by registries specify an "apple-head" or "apple-dome" skull conformation.[nine] Chihuahuas have large, round eyes and large, cock ears, prepare in a loftier, dramatically rounded skull.[8] The stop is well defined, forming a most-xc-degree angle where the muzzle meets the skull.[ten] Dogs of the older "deer" type, with a flat-topped caput, more widely set eyes, larger ears, and longer, more slender legs, may withal exist registered.[ix] [x]

Breed standards for this dog practice not more often than not specify a peak; simply a weight and a description of their overall proportions. Generally, the height ranges between 6 and 9 in (15 and 23 cm);[8] notwithstanding, some dogs grow equally tall as 30 to 38 cm (12 to 15 in). Both British and American breed standards state that a Chihuahua must non weigh more than 5.9 lb (2.7 kg) for conformation.[viii]

Withal, the British standard also states that a weight of 4–vi lb (i.viii–2.7 kg) is preferred. A clause stating "if two dogs are equally proficient in type, the more than atomic one is preferred" was removed in 2009.[11] The Fédération Cynologique Internationale standard calls for dogs ideally between ane.5 and 3.0 kg (3.iii and 6.six lbs), although smaller ones are adequate in the show ring.[12]

Pet Chihuahuas (those bred or purchased equally companions rather than as show dogs) often range above these weights, even higher up 10 lb (4.v kg), if they have large os structures or are allowed to become overweight.[8] This does not mean that they are not purebred Chihuahuas; they just do non run into the requirements to enter a conformation show. Oversized Chihuahuas are seen in some of the best, and worst, bloodlines. Chihuahuas do not breed true for size, and puppies from the same litter can mature in drastically unlike sizes from one another. Besides, larger breeding females are less likely to experience dystocia (obstructed labour). Many breeders try to breed Chihuahuas to be every bit small-scale as possible, because those marketed every bit "teacup" or "tiny teacup" need college prices.[13]

Chihuahuas occur in almost any color combination, from solid to marked or splashed.[14]

The Fédération Cynologique Internationale, which represents the major kennel clubs of 84 countries, disqualified the merle coat pattern, which appears mottled.[12] In May 2007, The Kennel Order decided non to annals puppies with this coloration due to the health risks associated with the responsible gene, and in December of that year, formally amended its breed standard to disqualify merle dogs.[15]

Like many other small dogs, the Chihuahua may display to a higher place-average aggression towards people and other dogs.[xvi] [17]

Health [edit]

The Chihuahua has some predisposition to several neurological diseases, amidst them atlantoaxial instability, ceroid lipofuscinosis, congenital deafness, congenital hydrocephalus, muscular dystrophy, necrotizing meningoencephalitis and neuroaxonal dystrophy.[xviii] : 3 [nineteen] In a radiographical study of canine periodontal affliction in 2001, the Chihuahua was found to have the everyman incidence of whatever of the six breeds studied.[20] : 206 [21] : 532
