The Chihuahua is a small breed belonging to the Toy group, originating from the state of Chihuahua in northern Mexico. It is one of the oldest dog breeds, with historical evidence tracing back to ancient civilizations like the Aztecs.
Chihuahuas are characterized by their apple-shaped heads and large, erect ears. They come in two coat varieties: Long Coat and Smooth Coat, both of which can display a wide range of colors, including fawn, black, white, and chocolate.
Known for their vibrant personalities, Chihuahuas are alert, energetic, and intelligent. However, their small size can make them prone to anxiety and wariness around strangers and other dogs. With proper socialization and training from a young age, they can develop a confident demeanor and become less reserved. Chihuahuas are fiercely loyal to their owners and make excellent companions for adults, though they may not be suitable for families with very young children due to their delicate frames. They adapt well to apartment living and do not require extensive exercise.
Generally, Chihuahuas are long-lived dogs, typically facing health issues such as dental problems, luxating patellas (dislocated kneecaps), and hydrocephalus. As puppies, they need frequent meals throughout the day to prevent low blood sugar levels, which can occur more easily than in larger breeds.
On average, Chihuahuas stand between 13-20 cm (5-8 inches) tall and weigh between 0.5-3 kg (1-7 lbs) as adults, with an average lifespan of 14-16 years.
