What people love about Chihuahuas

Chihuahuas may be tiny, but they have a way of making a big impression on the people who love them:

• Deep loyalty and devotion often lead to incredibly strong bonds with their people.
• Their compact size makes them easy to live with in apartments, units, and smaller homes.
• A long lifespan means many Chihuahuas become cherished companions for well over a decade.

Important things to consider

Chihuahuas can make wonderful companions in the right home. Before bringing one into your family, it's worth considering the following to ensure you're a great match for each other:

• Early socialisation helps build confidence around unfamiliar people, dogs, and environments.
• Despite their tiny size, they still benefit from daily exercise, enrichment, and opportunities to explore.
• Consistent, positive training is important, particularly when it comes to barking and household manners.
• Their small stature means extra care or supervision may be needed around larger dogs, busy environments, and young children.
• As Chihuahuas form strong bonds with their people, gradual independence training can be helpful to build confidence when spending time alone.
• Regular dental care plays an important role in supporting long-term health and wellbeing.

History & Origins of the Chihuahua

The Chihuahua is believed to have originated in Mexico and is considered one of the oldest dog breeds in the Americas. Historians believe the breed descended from the Techichi – a small companion dog kept by the ancient Toltec civilisation.

The modern Chihuahua was later discovered in the Mexican state of Chihuahua during the 1800s, where the breed gained popularity internationally. Today, Chihuahuas are one of the world's most popular companion breeds, admired for their small size, expressive personalities, and devoted nature.

Personality & Temperament 

Chihuahuas may be tiny, but they often have enormous personalities. Many are confident, spirited, and deeply attached to their owners. They love attention and often enjoy being close to their favourite person whenever possible.

While often portrayed as bold and fearless, many Chihuahuas are also sensitive little dogs who thrive when treated with patience, consistency, and kindness. Their strong bond with their family means they often enjoy being involved in everyday activities and spending time close to their people.

Trainability & Behaviour

Chihuahuas are intelligent dogs and can learn quickly with positive reinforcement training. While they can sometimes have an independent streak, short, positive training sessions often work best, helping keep them engaged and motivated. With consistency, clear guidance, and plenty of encouragement, Chihuahuas can develop into confident, well-mannered companions that enjoy learning and spending time with their people.

Common behavioural traits and challenges seen in Chihuahuas may include:

• Barking at noises, strangers, or visitors
• Separation anxiety
• Toilet training challenges
• Building confidence around unfamiliar people and environments

Sociability

Chihuahuas are naturally alert little dogs and are often quick to notice unfamiliar people, visitors, and new surroundings. While some may be cautious at first, many become friendly and affectionate once they feel comfortable and secure.

Although many Chihuahuas are highly social with their family, they may take a little longer to warm up to strangers. Positive exposure to visitors, different environemnts, and everyday experiences from an early age can help build social confidence and encourage positive interactions throughout life.

Do Chihuahuas get along with...

Children?

Chihuahuas can form strong bonds with children and enjoy being part of family life. Due to their small size, they generally do best with older children who understand how to handle dogs gently and respectfully. Supervision is always recommended during interactions with young children.

Other dogs?

Many Chihuahuas can live happily with other dogs, particularly when socialised from a young age. Despite their small stature, they often have plenty of confidence and may not always realise they're the smallest dog in the room.

Cats and other pets?

Chihuahuas can coexist well with cats and other household pets when introductions are managed thoughtfully. Positive experiences as a puppy can help build strong relationships between pets.

Strangers?

Many Chihuahuas prefer to approach new people at their own pace. Given time and positive introductions, many become more comfortable and confident around visitors and new acquaintances.

What to expect as your Chihuahua grows

Chihuahuas go through several developmental phases, each with their own unique needs.

Puppyhood (0–11 months)

The first twelve months of a Chihuahua's life are full of growing and learning. During this stage, you and your Chihuahua may experience:

• Rapid learning and social development
• Teething and chewing
• Toilet training challenges
• Strong attachment to owners

During this phase, care is focused on healthy growth and helping your Chihuahua build confidence. Positive experiences with people, animals, and new environments can help them develop into a well-adjusted adult dog. Because Chihuahuas are so small, puppy-proofing your home is especially important to help prevent accidental injuries.

Adulthood (1 – 8 years)

Once your Chihuahua has finished growing, they officially enter adulthood. As they mature, you may notice your Chihuahua:

• Settle into their adult personality
• Form very strong bonds with family members
• Enjoy a predictable routine of exercise and companionship
• Continue benefiting from training and mental enrichment
• Require food portions adjusted to maintain a healthy weight

These are your Chihuahua's prime years. Focus on maintaining their health, happiness, and quality of life through regular exercise, enrichment, and preventative healthcare.

Senior years (8+ years)

As your Chihuahua enters their golden years, you may notice:

• Reduced activity levels and increased sleep
• Greater appreciation for warmth and comfort
• Changes in vision, hearing, or mobility
• More frequent veterinary visits

During a Chihuahua's senior years, care focuses on supporting ageing bodies and maintaining comfort. Appropriate nutrition, regular veterinary care, and a comfortable home environment can help them continue enjoying life well into their later years.

Caring for a Chihuahua

Food and Nutrition

As a toy breed, Chihuahuas should be fed a complete and balanced diet formulated for mini, toy, or small breeds that matches their life stage. Because of their small size, even small changes in food intake can affect their weight. Monitoring your Chihuahua's body condition and adjusting portions when needed can help support a healthy weight throughout their life.

Chihuahua Age	What to Feed
8 weeks - 11 months	Small or mini breed puppy food
1–8 years	Small or mini breed adult dog food
8+ years	Small or mini breed senior dog food

Exercise and Mental Stimulation

Adult Chihuahuas generally benefit from around 30–60 minutes of daily activity depending on their age and fitness level. This activity should be spread out over multiple, shorter sessions throughout the day. This can include:

• Short walks
• Indoor play
• Sniffing activities
• Training games
• Food puzzles

Although they’re small, Chihuahuas still need regular mental stimulation and opportunities to explore the world safely. Many enjoy activities such as scent games, food puzzles, and training exercises that provide both mental enrichment and physical activity.

Space Requirements

As one of the smallest dog breeds, Chihuahuas are well suited to apartments, units, and smaller homes. They don't require a large backyard, but they do benefit from daily walks, play sessions, and opportunities to explore their environment.

Many Chihuahuas are happiest when they can spend plenty of time close to their family. With regular exercise, enrichment, and companionship, they can thrive in a wide variety of living situations.

Grooming Needs

Regular grooming not only helps keep a Chihuahua’s coat looking its best but also supports their skin health and provides opportunities for early detection of issues such as skin irritation, parasites or lumps.

Chihuahua grooming needs vary slightly depending on coat type, with long-coated Chihuahuas requiring more frequent coat maintenance.

A Chihuahua’s typical grooming routine will include:

• Weekly brushing – more frequent for long-coated Chihuahuas
• Occasional baths
• Regular nail trims
• Daily dental care

Common Health Issues in Chihuahuas

Being proactive with health care helps keep your Chihuahua happy and healthy. Stay up to date with preventative care, such as vaccinations and parasite protection, and visit your veterinarian regularly for health checks to identify and address any issues early.

Some common health conditions seen in Chihuahuas include:

• Luxating patella – a kneecap that has dislocated or slipped out of place, causing discomfort or intermittent lameness.
• Dental disease – a common condition in toy breeds that can lead to bad breath, gum disease, and tooth loss if left untreated, making regular dental care particularly important.
• Heart disease – including congestive heart failure and some congenital diseases
• Collapsing trachea – weakness in cartilage of the trachea causes it to collapse, impacting breathing
• Eye conditions – including glaucoma, cataracts, and dry eye
• Hydrocephalus – a congenital disease where fluid accumulates on the brain
• Hypoglycaemia – low blood sugar, particularly in puppies
• Obesity

Make sure you know how to recognise signs of illness and pain in dogs. Early intervention can greatly improve health outcomes.

How much does a Chihuahua cost?

Before bringing a Chihuahua home, it's important to understand the ongoing costs involved in caring for a dog. While Chihuahuas are one of the smallest dog breeds, they still require ongoing investment in food, healthcare, training, and everyday care throughout their lives.

Initial costs

• Purchase or adoption fee: The cost of a Chihuahua puppy can vary depending on whether you buy from a reputable breeder or adopt from a shelter or rescue. Adoption fees are generally lower and help support animal welfare organisations.
• Desexing: If your Chihuahua is not already desexed, this is an important one-off cost to consider.
• Microchipping: A legal requirement in many areas. A breeder or rescue may have had your dog microchipped before you brought them home.
• Vaccinations: After the initial course, vaccinations will be an ongoing annual cost.
• Basic supplies: Bed, crate or playpen, bowls, lead, harness, toys, and grooming tools. These may need replacing at least once during your dog's lifetime.

Ongoing costs

• Food: Chihuahuas require a complete and balanced toy or mini breed diet suited to their life stage. While their small size means lower food costs than many larger breeds, quality nutrition remains important.
• Health care: Includes routine preventative healthcare, such as annual health checks, vaccinations, parasite prevention, and any unexpected illnesses or injuries.
• Grooming: Smooth-coated Chihuahuas are relatively low maintenance, while long-coated Chihuahuas may require more frequent brushing and occasional professional grooming.
• Training and enrichment: Puppy School, toys, and enrichment activities can help build confidence and encourage positive behaviours.
• Pet insurance: Highly recommended to help manage unexpected veterinary expenses throughout your dog's life.
• Registration: Many councils require you to pay an annual registration fee for your dog. Check your local council's website for details.

Best names for a Chihuahua

When naming your Chihuahua, think about a name that will suit your dog. You might consider:

• A name that suits their tiny size
• A name that matches their big personality
• A cute or cheeky nickname
