Canis lupus familiaris

Chihuahuas are known for their vivacious and loyal personality, often forming a strong bond with a single person. Despite their small size, they have a bold and confident demeanor, sometimes unaware of their diminutive stature.

Breeding Chihuahuas requires attention to health issues such as heart problems, patellar luxation, and dental issues due to their small mouths. Ethical breeders prioritize health, temperament, and conformation to breed standards.

Chihuahuas possess a distinctive apple-shaped head, large, expressive eyes, and can have either a smooth or long coat in a wide range of colors and patterns. They are compact and agile, with a typical weight of 2-6 pounds.

The Chihuahua's ancestors were believed to be companion dogs to the ancient civilizations of Mexico, including the Toltecs and the Aztecs. The breed was named after the Mexican state of Chihuahua, where it was discovered in the mid-19th century.

Chihuahuas remain immensely popular, particularly as companion pets in urban environments due to their small size and adaptability to apartment living. Ongoing efforts by breed enthusiasts and clubs focus on promoting responsible ownership and addressing health concerns through conscientious breeding practices.
