The Chihuahua is a tiny dog with a huge personality.
A national symbol of Mexico, these alert and charming little dogs stand among the oldest breeds of the Americas, with a lineage tracing back to pre-Columbian times.
Their ancestor is the Techichi, a small companion dog indigenous to Central America. They are named after the Mexican state of Chihuahua, where early examples of the breed were first identified.
Chihuahuas come in two coat varieties—smooth coat and long coat—and often form strong bonds with their families.
Chihuahua Appearance
Chihuahuas are five to eight inches tall, with bodies that are slightly longer than they are tall. They weigh no more than six pounds.
The breed comes in two coat varieties, each with slightly different grooming needs. Smooth-coat Chihuahuas require occasional brushing and regular baths, while long-coated Chihuahuas benefit from weekly brushing to prevent tangles and keep the coat healthy.
Both varieties shed lightly year-round, with occasional seasonal increases. Puppies naturally lose their softer puppy coat as their adult coat grows in. Begin gentle grooming and bathing around 10 weeks old so your Chihuahua becomes comfortable with the routine.
Temperament/Personality
Chihuahuas have a life expectancy of 14 to 16 years. They are alert, confident, and full of character, even as senior dogs.
Despite their size, they behave like big dogs and benefit from consistent training early on. Their awareness of their surroundings makes them excellent watchdogs, though they may bark more than some breeds.
Compact and adaptable, Chihuahuas thrive as city pets. Because of their small size, they are not ideal for rough play with young children, and they require extra care in cold weather. They tend to bond deeply with their people and may feel overwhelmed in homes that are loud or chaotic.
Individual personalities vary widely—some Chihuahuas are bold and energetic, others more mellow or reserved. Some end up being very funny dogs!
Genetics, socialization, and training all shape temperament. While they love being close to their humans, they can become stressed by fast movements and loud noises, which may lead to fearfulness if not properly socialized.
Caring for a Chihuahua
Next, we’ll go into how to care for a Chihuahua.
Nutrition
Feed a high-quality dog food appropriate for your Chihuahua’s age (puppy, adult, or senior). Some Chihuahuas can gain weight easily, so keep an eye on portion sizes and calorie intake.
Treats can support training but should be given in moderation.

Avoid cooked bones and high-fat table scraps, and learn which human foods, like cranberries and (some parts of) turkey, are safe for dogs.
Fresh water should always be available. Your veterinarian can help tailor a diet plan to your dog’s needs.
Exercise
Even small dogs need daily activity. Chihuahuas love to run and play and can meet much of their exercise needs indoors or in small spaces.
Following their people around the home often provides plenty of movement. Short, relaxed walks are usually enough to keep them in good condition.
Avoid overexertion—if your Chihuahua is panting heavily or struggling to keep up, it’s time for a break or a ride home in your arms.
Training
Chihuahuas are clever, attentive, and eager to please. They respond best to positive, reward-based training. Because they learn quickly, they may also learn how to get their way if boundaries are not set early.
Instead of harsh corrections, use clear, consistent cues and gentle guidance. With good training and socialization, Chihuahuas can excel in obedience and other canine sports.
Health
Most Chihuahuas are healthy, but some genetic conditions can appear in the breed.
Potential issues include heart conditions (such as patent ductus arteriosus and mitral valve disease), patellar luxation (unstable kneecaps), and certain eye disorders. Hypoglycemia may occur in young puppies, especially toy breeds, but usually becomes less common as they mature. Epilepsy and other neurological conditions can also occur in some lines.
Routine care remains essential: trim nails regularly, maintain good dental hygiene, and clean ears gently with a soft cloth or cotton ball to prevent infections. Gum disease is common in small breeds, so regular dental care and vet checkups are especially important.
