Chihuahua

Tiny body, huge personality — a loyal, spirited pocket companion.

Chihuahuas are the smallest dog breed, with a confident, alert personality. They bond deeply with their people and live long lives, but they need gentle handling, careful socialisation and attention to dental and joint health.

Ratings describe typical dogs of the breed on a 1–5 scale. Individual dogs vary with lines, upbringing and training.

Temperament

Chihuahuas are devoted and often attach strongly to one person. They are lively, curious and alert, making them quick to bark at visitors. Well-socialised Chihuahuas are confident, playful and affectionate.

Their small size makes them easily hurt and easily frightened, which can lead to defensive snapping. Treat them as real dogs — train them, socialise them and let them walk — rather than carrying them everywhere.

Varieties

Smooth coat
Short, glossy coat; the most common variety.
Long coat
Soft, flowing coat with ear and tail feathering; needs more brushing.

Living with a Chihuahua

Exercise

Two short walks and indoor play daily. Use a coat in cold weather — they chill quickly.

Grooming

Weekly brushing (more for long coats). Daily tooth brushing is important; dental disease is very common.

Training

Smart but can be stubborn. House-training can take time; a covered indoor toilet option helps in bad weather. Socialise early to prevent fearfulness.

Kids & other pets

Best with adults or older, gentle children. Usually happiest with other small dogs.

Time alone

Can cope with moderate alone time but often form strong attachments.

Home fit

Adapts well to apartments and smaller homes when daily needs are met.

Health

With good breeding and care, a Chihuahua typically lives 14–16 years. These are the conditions most associated with the breed — not a prediction for any individual dog.

  • Dental disease

    Crowded teeth in small jaws cause early tartar and tooth loss. Brush daily.

  • Patellar luxation

    Kneecaps that slip are common in toy breeds.

  • Tracheal collapse

    Weak windpipe cartilage causes a honking cough; use a harness, not a collar.

  • Hypoglycaemia

    Puppies can suffer dangerously low blood sugar if they miss meals.

  • Mitral valve disease

    A common heart condition in older small dogs.

  • Patella evaluation
  • Cardiac examination
  • Eye examination

After the first year, expect roughly $900–$1,800 a year for food, routine vet care, preventives, insurance and supplies (US estimate).

  • Pet insurance for a puppy typically runs $30–$60 a month; premiums rise with age and breed risk.

History

Chihuahuas are believed to descend from the Techichi, a companion dog of the Toltec and later Aztec civilisations in Mexico. Archaeological artefacts show similar small dogs dating back more than 1,000 years.

The breed is named after the Mexican state of Chihuahua, where Americans found the dogs in the mid-1800s. The AKC registered its first Chihuahua in 1904.

  • Many Chihuahuas are born with a molera, a soft spot on the skull similar to a baby’s fontanelle.
  • A Chihuahua named Pearl was listed by Guinness as the shortest living dog, at 9.14 cm tall.
  • The Taco Bell Chihuahua made the breed famous in the late 1990s.
