Chihuahua

The world's smallest dog with the world's biggest attitude.

At a glance: Tiny but fearless, the Chihuahua is a devoted one-person dog with a huge personality and a sharp watchdog bark. It's portable and low-maintenance but can be snappy if spoiled or unsocialised, and its small size makes it fragile around young children.

Temperament

Descended from the Techichi dogs of ancient Mexico, the Chihuahua was never bred to work — only to be with someone, completely. That wiring produces a saucy, terrier-like companion that picks its person, guards them from sofas and doorways, and treats dogs twenty times its size as equals, which is both its charm and its danger.

BreedQuest census: Many Chihuahuas are born with a molera — a soft spot in the skull, like a human baby's — that may never fully close.

Habits & quirks

The burrower

Under blankets, under cushions, under your jumper — a Chihuahua nests wherever warmth lives.

Shiver mode

It trembles when cold, excited or dramatic, which is often; keep a jumper handy.

One true person

It loves the household but worships one member with total, jealous devotion.

Big-dog delusion

It will square up to Great Danes on principle — your job is to prevent the rematch.

Care

FeedingGrams matter at this size — measure meals, go easy on treats, and never free-feed.
Dental careTiny jaws crowd teeth; daily brushing and vet dental checks prevent early tooth loss.
SafetyProtect from falls, rough toddlers and large dogs — a knee-height jump is a cliff to a 2 kg dog.
TrainingSocialise early and train it like a real dog — carried everywhere and never told no, it becomes a tyrant.

Common questions

Are Chihuahuas good with children?

Better with gentle older children — they're tiny and fragile, and can be defensive if handled roughly. Supervise closely with toddlers.

Do Chihuahuas bark a lot?

They can — they're alert and territorial little watchdogs. Early socialisation and training curb excessive barking and wariness.

How long do Chihuahuas live?

Often 14–16 years, and some go well beyond — they're among the longest-lived of all breeds. Good dental care and a lean weight are the best predictors of a long run.
