🐾 Small · Mexico
The world's smallest dog breed — bold, devoted and long-lived, but delicate in build and easily overindulged.
The Chihuahua is confident, bold and closely bonded to its owner. Despite its miniature size, it carries itself with an outsized sense of self and tends to behave as though it were a much larger dog. Without proper training, it can quickly develop into a yappy, overprotective little guard.
Exercise needs are low and easily met indoors; short walks and play sessions are sufficient. Consistent socialization matters more than physical exercise, so the small dog doesn't turn into a nervous little tyrant.
The breed comes in smooth-coat and long-coat varieties, both low-maintenance. Because of their small body mass, Chihuahuas chill quickly and often need a coat in cold weather.
Suitable for beginners only with caveats: apartment-friendly and easy to groom, but fragile (at risk of injury from falls or being stepped on) and prone to being overprotected. Less suitable for households with young children.
Breed-typical issues include patellar luxation, an open fontanelle in the skull (molera), dental and gum problems, and hypoglycemia in puppies. Extremely small teacup lines are especially vulnerable and should be avoided.
