Chihuahua

The traditional pure Chihuahua has a fingertip-sized indentation on the top of its head, which is also an important criterion for people to distinguish whether a Chihuahua is pure or not. The Chihuahua is best with a round "apple-shaped" head. The expression is beautiful, the eyes are large but not protruding, symmetrical, and preferably bright black or red (white eyes are allowed in fawn or white dogs). The ears are large and erect, and remain upright when alert, but when at rest, the ears are separated and the angle between the two ears is 45 degrees. The muzzle is short and slightly pointed. The nose color of black, blue and chocolate varieties is consistent with their body color. Fawn varieties are allowed to have pink noses. Scissor bite or pincer bite. Overshot or undershot is a serious fault. The body is rectangular in proportion; so the length from shoulder to hip is slightly greater than the height at the shoulder. It is ideal for males to be slightly shorter.

Native to South America

The history of the Chihuahua from Mexico to the United States until 1898 is still unclear. Some people have determined that this dog originated in South America and was initially regarded as a sacred dog by the Incas, and later spread to the Astica. Others believe that this dog is a breed that arrived in the New World with Spanish invaders, or was introduced from China in the early 19th century. The above judgments can show that this dog is not derived from a single breed, but has been the result of mating of multiple breeds since ancient times.

Chihuahua was recognized by the American Kennel Club (AKC) in 1904 and recognized by the World Canine Federation (FCI) in 1959. The British Chihuahua Club was established in 1949 and is the smallest dog in the world. The Chihuahua Club was established in 1923. It is one of the 12 most popular dog breeds in the United States.

According to the Yomiuri Shimbun, a 7-year-old female long-haired Chihuahua has passed the review of the Japanese Special Police Dog Review Committee and officially took up the post as a police dog in January 2011 to participate in disaster rescue work. The Chihuahua is named "Kotoko", a small dog weighing only 3 kilograms. Her owner is Ms. Yoshimatsu Keiko from Sakurai City, Nara Prefecture, Japan. In the "Search and Rescue Project" test of the review committee, Kotoko found the helper within a radius of 100 meters within 5 minutes with the help of information obtained from the items left behind by the helper, and successfully passed the test. According to people familiar with the matter, Kotoko received guidance from a trainer 6 years ago. Her movements are flexible and agile, and she showed her rescue talent early. Although there are few cases of Chihuahuas serving as special police dogs, Kotoko's success has broken people's stereotypes about Chihuahuas. Even in certain specific situations, the petite Chihuahua can enter some narrow gaps and complete search and rescue tasks that large dogs cannot complete.

Chihuahuas have strong wills, elegance, vigilance, and clinginess. They don't like foreign dogs of the same breed, and have similar characteristics to terriers; they are energetic; Chihuahuas have strong wills, but they are afraid of cold and are not suitable for outdoor kennels. They need to wear outer clothes to keep warm in winter. They are quick in action and are widely loved by people for their well-proportioned physique and petite size. This dog is divided into long-haired dogs and short-haired dogs. Although this dog is small in size, it is not timid to other dogs, but very brave. It can defend itself in front of large dogs and is very possessive of its owner. They don't exercise much every day, and you don't need to spend time taking it out to play. It is very suitable for people living in apartments to keep them at home every day.
