The Chihuahua is a small breed of dog that originated in Mexico and dates back to the 19th century. It is believed that the breed was descended from the Techichi, a companion dog of Aztec Indians. The first recorded appearance of this breed happened in 1850 in Chihuahua, Mexico when two dogs were brought to America by miners. The Chihuahua gained popularity in America during the late 1800s and early 1900s after it was featured as a pet of wealthy Americans like Elizabeth Taylor, Joan Crawford, and Marcia Gay Harden. In 1904, they were officially recognized by the American Kennel Club (AKC) as part of their Toy Group classification. Today’s modern Chihuahuas are known for their loyal and affectionate natures and have become popular family pets around the world due to their size and adaptability to city living. They are also one of the most recognizable breeds due to their unique look which includes large ears and almond-shaped eyes with an apple head shape on smaller dogs or deer head shape on larger ones.
