Australia's smallest pure breed, the Chihuahua packs outsized personality into a 2kg frame. Loyal to one or two people and suspicious of everyone else unless socialised hard.
Chihuahua temperament
Confident, alert, and fiercely bonded. Can be nippy if not trained out of small-dog syndrome. Socialise heavily from 8 weeks.
History in Australia
Ancient Mexican origin, descendants of the Techichi companion dog of the Toltecs. Kennel Club standardised in the 1900s.
Who the Chihuahua suits
Good for:
- Apartment living
- Single-person or couple households
- Seniors and retirees
- Travellers
Watch out for:
- Fragile — not suitable for young children
- Prone to excessive barking
- Cold-sensitive
- Dental disease (overcrowded mouth)
Training a Chihuahua
Treat like a real dog — consistent rules, no 'it's cute because she's tiny' excuses for nipping or growling. Positive reinforcement works; small treats to avoid weight gain.
Owning a Chihuahua in Australia
Microchipping, council registration, desexing, strata by-laws and restricted-breed rules apply to every dog in Australia regardless of breed. The state-by-state detail is in our guide to Australian dog ownership laws.
What matters specifically for a Chihuahua: toy-sized dogs attract the lower end of council registration fees, and generally clear the size conditions strata schemes are permitted to impose. Budget $25 – $45/month on food, on top of the $400–900/year in routine care every Australian dog owner carries.
Common Chihuahua health issues
- Dental disease
- Patellar luxation
- Hydrocephalus (teacup sizes)
- Hypoglycaemia in puppies
- Tracheal collapse
Insurance note: Low-moderate premiums. Dental disease and patellar luxation dominate claims. Many insurers sub-limit dental treatment — check the annual dental cover cap.

Frequently asked questions
How long do Chihuahuas live?
14–18 years is common. Well-cared-for Chis reaching 20 isn't unusual — one of the longest-living breeds.
Are Chihuahuas good with kids?
Not ideal with young children. Their fragility and tendency to nip when startled make them better suited to households without toddlers.
Do Chihuahuas need much exercise?
20–30 min walk daily plus indoor play. Easy to meet their needs — they're one of the easiest breeds for apartment living.
