Chihuahuas often get underestimated on the basis of size alone, but the breed's confidence, and occasional feistiness, tends to surprise first-time owners expecting a purely lap-sized companion. They bond intensely, often gravitating toward one person in particular within a household.
Temperament
Alert, loyal, and often wary of strangers, sometimes vocally so. Chihuahuas can develop a strong one-person bond and may show jealousy or possessiveness if not socialized broadly early on.
Exercise and energy
Surprisingly energetic for their size, though their small stature means exercise needs can be met with shorter walks and indoor play compared to larger breeds. Mental stimulation matters as much as physical activity.
Grooming needs
Both smooth and long-coat varieties exist. Smooth coats need minimal grooming; long coats need weekly brushing to prevent tangling, though neither variety sheds especially heavily.
Health considerations
Prone to dental crowding given their small jaw size, along with patellar luxation and, in some lines, a soft spot in the skull called an open fontanelle that requires extra care in puppyhood. Their small size also makes them vulnerable to injury from falls or rough handling.
Good fit for
Owners who want a devoted, portable companion and are prepared to manage a sometimes wary temperament around strangers and children. Less ideal for households with young kids who may not handle a small, fragile dog gently enough.
Frequently asked questions
Are Chihuahuas good with children?
It varies by individual dog and depends heavily on socialization. Their small, fragile build means supervision matters more than with a sturdier breed, regardless of temperament.
Why do Chihuahuas seem to shiver so often?
Partly genuine cold sensitivity from their small body size and low body fat, and partly excitement or anxiety, which can produce a similar shiver. Context usually clarifies which is happening.
