Chihuahuas are alert, lively and affectionate dogs with confident personalities that can seem much larger than their tiny bodies suggest. They often form close bonds with their owners and enjoy being involved in everyday family life. The breed standard describes the ideal Chihuahua as spirited and intelligent, without being snappy or withdrawn.
Some Chihuahuas can be reserved or vocal around unfamiliar people and dogs, making early positive socialisation important. Their intelligence and awareness of their surroundings also make them effective little watchdogs, although appropriate training can help prevent alert barking from becoming excessive.
Chihuahuas are ideal city pets, being well-suited to apartment- and smaller-home living.
Chihuahuas can make affectionate family companions, but their extremely small and delicate bodies mean they are generally better suited to older children who understand how to handle dogs gently. Young children should always be supervised closely, as accidental falls, squeezing or rough play can cause serious injury to such a tiny dog.
They can also live successfully with other dogs and pets when appropriately socialised. Particular care is needed around much larger dogs, which can accidentally injure a Chihuahua during play. Dogs with a strong prey drive may also need careful supervision around such a small companion.
Although tiny, Chihuahuas are energetic dogs that benefit from daily exercise and play. Around 20–30 minutes of dedicated activity each day is generally sufficient for most healthy adults, although many enjoy additional indoor play, short walks and opportunities to explore. Exercise needs should be adjusted for the dog’s age, health and individual energy level.
Chihuahuas are intelligent and capable learners but can also be independent and strong-willed. Short, enjoyable training sessions using positive reinforcement generally work well. Early socialisation, house training and teaching calm behaviour around unfamiliar people and dogs are particularly useful.
Because of their small size, owners should avoid relying on carrying them everywhere. Regular opportunities to walk, sniff, play and interact appropriately with the world help support confidence and normal behaviour.
| Energy level | High: lively and playful despite their tiny size |
| Exercise requirements | Low to medium: around 20–30 minutes daily plus indoor play and mental enrichment |
Chihuahuas are generally long-lived and relatively healthy, but prone to several dental, joint, cardiac, airway and eye conditions.

Chihuahuas should be fed a complete and balanced diet appropriate for their age, body condition, activity level and health. Because their calorie requirements are very small, even seemingly modest amounts of treats or table food can contribute to weight gain, so portions should be measured carefully. Young Chihuahua puppies may require more frequent meals because their tiny size can make them susceptible to hypoglycaemia.
Maintaining good dental health is also particularly important, with daily tooth brushing and regular veterinary dental checks recommended. Speak to your vet if you have concerns about your Chihuahua’s diet, weight or feeding schedule.
Chihuahuas have relatively straightforward grooming needs, although care varies between the two coat varieties. Smooth Coat Chihuahuas generally benefit from weekly brushing, while Long Coats should be brushed several times a week to prevent tangles and keep feathering in good condition. Both varieties shed, although the amount varies between individuals.
Dental care is especially important in this breed, and daily tooth brushing is ideal. Routine nail and ear care should also form part of their grooming routine.
The Chihuahua is a tiny, dainty and compact dog with a distinctive rounded “apple dome” skull, moderately short pointed muzzle and large, widely spaced ears. The eyes are large and round but should not protrude. Despite their tiny size, Chihuahuas should move briskly and confidently.
The breed occurs in two coat varieties. Smooth Coat Chihuahuas have a soft, close and glossy coat, while Long Coats have soft, flat or slightly wavy hair with feathering on the ears, legs and tail and often a fuller ruff around the neck. Almost any colour or colour combination is permitted under the Dogs Australia standard, but merle is not accepted.

The Chihuahua takes its name from the Mexican state of Chihuahua and is considered one of the oldest dog breeds of the Americas. Its precise ancestry is uncertain, but the breed is widely associated with the Techichi, a small companion dog kept by the Toltec civilisation in what is now Mexico around a thousand years ago. The Aztecs later kept similar small dogs and incorporated them into both everyday and ceremonial life.
During the 19th century, American visitors to Mexico began acquiring small dogs from the Chihuahua region and bringing them back to the United States. Interest in the breed grew, and the American Kennel Club formally recognised the Chihuahua in 1904. Smooth and Long Coat Chihuahuas are two varieties of the same breed rather than the result of modern crosses with breeds such as Pomeranians or Papillons.
The first Chihuahuas were imported into Australia during the 1930s, with the breed becoming more established in Sydney during the 1950s. Dogs Australia today recognises Smooth Coat and Long Coat Chihuahuas separately within Group 1 (Toys).

The Chihuahua is a tiny, energetic dog with a big personality, expressive eyes and a distinctive apple-shaped head. Loyal and devoted, Chihuahuas often form a particularly strong attachment to one person.
Their confidence can make them protective, vocal or reserved around strangers, and their small size makes them better suited to considerate handling and households with older children. They adapt well to smaller homes but still need socialisation, activity and companionship.
They are generally affectionate companions and can suit families, couples or singles when their individual exercise, training and grooming needs are met.
Moderate. Daily walks and play are generally appropriate, adjusted for the dog’s age, health and individual energy level.
They are intelligent but can be independent or strong-willed, so patient, consistent reward-based training and early socialisation are important.
They are generally low to moderate or moderate barkers, although barking can increase with boredom, excitement, anxiety or unfamiliar activity.
Yes. They generally shed a low to moderate or moderate amount and benefit from routine brushing.
Yes, they can adapt well to apartment living provided they receive sufficient daily exercise, mental stimulation and companionship.
They can live happily with respectful children and other pets when well socialised, but their small or delicate size means interactions with young children should be closely supervised.
Potential health concerns include dental disease, patellar luxation, heart disease, eye problems and tracheal disorders.
They are two coat varieties of the same breed and share the same general size, temperament and physical standard. Smooth Coat Chihuahuas have short, close, glossy hair, while Long Coats have soft flat or slightly wavy hair with feathering on the ears, legs and tail. Long Coats generally require more frequent brushing.
