The Chihuahua is the world’s smallest dog breed. Despite its tiny size, it has a lot to offer, which is likely one of the reasons it has become so popular. With a Chihuahua, you get a dog that loves to cuddle, play, and enjoy your company.

Where do Chihuahuas come from?

While there’s some uncertainty about the Chihuahua’s early history, it’s believed that these dogs existed as early as the 1300s in Mexico. A small dog, known as the Techichi is depicted in the architecture of Tula and closely resembles today’s Chihuahua. These dogs were likely wild before being captured and domesticated, though their exact origins remain unknown.  

The breed was discovered by American travellers in 1895, who brought them back to the United States. They found them in Chihuahua, Mexico’s largest state, which is how the breed got its name. Today, the Chihuahua is popular worldwide and is recognised as the world’s smallest dog breed. 

Chihuahua temperament

Bold

Despite their small size, the Chihuahua has a big personality and a fiery temperament. Often acting like they’re a much larger breed. They’re independent and mentally strong, and know what they want.

Loyal

Chihuahuas are incredibly loyal and love to cuddle. Wrapped up n a blanket on your lap is often their happy place. They’re a true lapdog that craves closeness and will demand your attention if you don’t give it willingly.

Playful

Chihuahuas are agile, quick, and playful well into old age. They are also very protective of their home and owner. It’s important to set clear boundaries early on to prevent this from becoming excessive.

Vocal

Historically, the breed was used as a watchdog, so it can be quite vocal. Proper socialisation from puppyhood and positive reinforcement can help manage barking.

Bossy

Chihuahuas like to be in charge and will often boss around other dogs. This can lead to conflicts, especially with larger dogs, which may result in dangerous situations. Small dogs can be mistaken for prey by bigger dogs or accidentally injured.

Fiery

Ensuring early and proper socialisation with dogs of a similar size is crucial to prevent aggressive behaviour. Puppy and young dog training classes can be very beneficial.

Delicate

Chihuahuas are small and delicate so they may not be the best choice for families with young children. Rough handling or squeezing can have serious consequences. However, they do well with older children who understand how to treat them gently.

What do Chihuahuas look like?

The Chihuahua is a small, compact dog best known for its tiny size. It has large eyes and ears and comes in both short-haired and long-haired varieties.

The short-haired Chihuahua is the original, while the long-haired version was developed by crossing the breed with small spaniels. Both types follow the same breed standard but are separated for registration and dog shows.

In fact, both coat types can be born in the same litter but will be officially classified by their fur type in pedigrees. 

A Chihuahua typically weighs between 1–3 kg, with no official height standard.

Chihuahua grooming

A Chihuahua’s coat is relatively easy to maintain, even for long-haired varieties. Brushing once a week is usually sufficient, and during shedding periods, additional brushing can help keep loose fur off furniture and carpets. Apart from coat care, their nails should be trimmed regularly.

How to train a Chihuahua

  1. 1

    See what you can teach!

    Chihuahuas are intelligent and alert dogs that can learn almost anything their owner teaches them. 

  2. 2

    Provide lots of stimulation

    Despite their size, they function like any other dog and require both physical and mental stimulation. Without enough exercise, they may develop unwanted behaviours, particularly reacting strongly to perceived dangers. 

  3. 3

    Focus on activities

    Activities such as agility, obedience training, and nose work are excellent choices for this breed.  

  4. 4

    Use positive reinforcement

    Because they’re smart, they can sometimes be stubborn. If training lacks variety or motivation (such as tasty treats or fun activities), they may lose interest. 

  5. 5

    Be patient

    Patience and creativity are key when training a Chihuahua.  

  6. 6

    Keep them warm

    During colder months or heavy rain, Chihuahuas need protective clothing like a coat or jumper. They don’t tolerate cold weather well and dislike bad weather.

  • Tick icon

    Dental issues (retained baby teeth)

  • Tick icon

    Trauma (injuries from falls or being stepped on)

What we love most about a Chihuahuas

A true cuddle companion

If you love cosy moments on the sofa, plenty of affection, and playful interactions, you’ll adore a Chihuahua. They are incredibly loyal and thrive on attention. Plus, they’re small enough to take almost anywhere.

A big dog in a small body

Despite their tiny size, they have huge personalities and can do everything that bigger dogs can. They’re perfect for people who want a dog but have limited space.

Low-maintenance coat

Whether short-haired or long-haired, Chihuahuas don’t require excessive grooming, so you can focus more on bonding rather than brushing.

Things to consider before getting a Chihuahua

While Chihuahuas have many lovable qualities, there are a few challenges to be aware of.

  1. 1

    They can be vocal

    This breed tends to bark, which is natural but can be managed with training. However, if you want a completely silent dog, a Chihuahua may not be the best choice.  

  2. 2

    They have a protective nature

    Chihuahuas are very attached to their belongings and territory. Without proper training, their guarding instincts can become excessive.  

  3. 3

    Socialisation is essential

    Early socialisation is crucial for Chihuahuas to become well-adjusted and tolerant of other dogs. Due to their small size, it’s important to supervise interactions with larger dogs to prevent injuries.  

With the right training, socialisation, and care, a Chihuahua makes a wonderful companion full of personality and affection.
