The Smooth Chihuahua traces its origins to the ancient Chihuahua region of Mexico, where ancestors of the breed are believed to have held ceremonial significance in Aztec culture. The breed was introduced to the United States in the late 19th century and has since spread worldwide. The smooth-coated variety is distinguished by its short, sleek fur, which requires considerably less grooming than the long-coated type — a practical advantage many owners appreciate. They typically weigh between 1 and 3 kg and are recognized by their rounded "apple dome" skull and large, upright ears. Chihuahuas are bold, assertive, and deeply devoted to their owners, though they can be wary of strangers and unfamiliar dogs. Despite their small size, they are surprisingly energetic and can meet their exercise needs with short daily walks and indoor play. With a lifespan of roughly 13 to 16 years, a well-cared-for Chihuahua can be a loyal companion for many years to come.
1Sensitive to Cold
The smooth coat provides little insulation, making Smooth Chihuahuas prone to feeling cold. Use dog clothing and maintain a warm room temperature during cooler months. Providing mats or rugs can also help prevent them from getting chilled on cold floors.
2Fragile Bones
Their extremely small, delicate bones make Smooth Chihuahuas vulnerable to fractures from falls or accidental stepping. Use ramps or steps near furniture, and handle them carefully when carrying. Extra caution is needed around young children and large dogs.
3Strong One-Person Bond
Chihuahuas tend to bond deeply with one person while remaining cautious around strangers and unfamiliar dogs. Early socialization during puppyhood is important to help them feel comfortable in varied environments. Gradual introductions are especially valuable in multi-pet households or homes with frequent visitors.
4Managing Barking
Chihuahuas are alert and can bark in response to sounds or visitors. Teaching a "quiet" command consistently from a young age helps manage this tendency. For apartment dwellers, starting training early is considerate toward neighbors.
5Dental Care Matters
Like many small breeds, Chihuahuas are prone to dental disease. Establishing a regular tooth-brushing routine and scheduling periodic dental check-ups with a veterinarian are recommended. Introducing tooth brushing during puppyhood makes it easier to maintain as a long-term habit.
6Health Conditions to Know
Chihuahuas have known predispositions to conditions such as hydrocephalus, tracheal collapse, and patellar luxation. When acquiring from a breeder, review health check records and maintain regular veterinary visits. Early detection can contribute to better management of these conditions.
7Estimated Costs
The initial cost of a Smooth Chihuahua varies widely depending on lineage and quality, and can reach several hundred thousand yen. Ongoing expenses include monthly food, grooming (relatively low for the smooth coat), vaccinations, and veterinary care. Planning for long-term costs, including pet insurance, is advisable.
