Quick answer
The world's smallest dog breed has one of the biggest personalities. Originally from Mexico, the Chihuahua is bold, alert and very sure of its own importance, usually in a body weighing just 1.5–3kg. Exercise needs are modest, with up to 30 minutes of gentle walking and play a day, but training and socialisation matter as much as they would for a much bigger dog.
Plan for a small-breed diet sized for a tiny mouth, a warm coat for chilly days, and careful handling around bigger dogs, lively children and high furniture. Get those right and you'll have one of the most devoted, long-lived small dogs around.
Why Owners Love the Chihuahua
A short history and what makes the breed stand out
The Chihuahua is named after the Mexican state where it's believed to have been developed. It's thought to descend from the Techichi, a small companion dog kept by ancient civilisations in Mexico. Whatever its exact origins, one thing hasn't changed for centuries: this is a dog that has never thought of itself as small.
Once a Chihuahua joins the family, a few things stand out:
-
Big personality
Bold, alert and confident, a Chihuahua carries itself like the biggest dog in the room.
-
Devoted to their person
Chihuahuas often form a very close bond with one favourite person and follow them everywhere.
-
Easy-care coat
Smooth or long-coated, grooming needs are low, and an occasional brush is usually enough.
-
Long-lived
Many Chihuahuas live well into their teens, giving you many years together.
Bottom line: with consistent training, gentle handling and plenty of warmth on cold days, a Chihuahua becomes a fiercely devoted companion that will happily be by your side for well over a decade.

What to Plan for Before Getting a Chihuahua
The realities of owning the breed
A Chihuahua's tiny size and huge confidence are what people fall for, and both call for a little extra care and consistency at home.
-
Very delicate
Falls, rough handling or run-ins with larger dogs can cause serious injury, so supervision matters.
-
They feel the cold
Low body fat and a fine coat mean many Chihuahuas need a jumper or coat once the weather turns cool.
-
Watch for "small dog syndrome"
Without consistent boundaries, that confidence can turn into snappy, possessive or suspicious behaviour.
-
Strong bonds with one person
Devotion to a favourite person can come with wariness of strangers and difficulty coping when left alone.
-
Health screening matters
Talk to your breeder and vet about patellar luxation (slipping kneecaps), dental crowding and heart conditions. Many Chihuahuas also have a molera, a soft spot on the skull that needs gentle handling.
Common misconception: people often assume a dog this small barely needs training. In reality, a Chihuahua's boldness and lack of awareness of its own size mean early, consistent training matters just as much as it does for a far larger breed.
Puppy or Adult: Which Is Right for a New Owner?
Either can work well. A puppy needs especially gentle handling while its tiny bones develop, plus early socialisation so it doesn't become overly wary of strangers. An adult gives you a clearer picture of temperament and health from day one. Either way, consistent routines from the start make the biggest difference.
Is a Chihuahua Right for Your Home?
Not every household is the right fit, and that's fine. Use this as a rough guide, since every home is different:
-
Not ideal
Homes with lively young children or big dogs
Rough play is dangerous for such a tiny dog, and injuries happen far more easily than with a sturdier breed.
-
Can work well
Calm households, including flats
A settled routine, gentle handling and consistent training suit a Chihuahua, whatever the size of the home.
-
Best fit
Singles, couples and retirees
Owners who want a devoted lap dog and will commit to training and socialisation get the best from this breed.
Bringing Your Chihuahua Home
The first few months set the tone for the years ahead. Start with these four steps:
-
Puppy-proof for tiny paws
Chihuahuas can squeeze into gaps most dogs can't. Check behind and under furniture, and clear anything within reach at floor level before they arrive.
-
Book a vet check
Cover vaccinations, flea and worm treatment and a general health check, and ask about the molera (soft spot on the skull). Toy breed puppies can be prone to low blood sugar, so ask how often to feed.
-
Start gentle socialisation
Once your vet gives the go-ahead, introduce your Chihuahua to new people, places and calm dogs, keeping each experience positive. This helps prevent wariness later on.
-
Set a routine
Consistent boundaries and training from day one help prevent small dog syndrome. Bite-sized rewards such as our Mini Chicken Training Bones keep short sessions positive without overfeeding. Practise short, calm spells of time alone to build independence.
When to think twice: if your home includes very young or boisterous children, large excitable dogs, or consistent training isn't realistic for you, it will be hard to keep a Chihuahua safe and meet its needs. It's worth weighing this up before you commit.
Feeding Your Chihuahua
Chihuahuas do best on a fresh, high-quality diet sized for their tiny stomachs. As the smallest dog breed, even a few grams too much or too little makes a noticeable difference. They can also be prone to dips in blood sugar, so smaller, more frequent meals often suit them better than one or two large ones. Extra weight affects a dog this size far more, so feed by weight, life stage and activity. Most adults do well on two or three small meals a day.
For dogs with sensitive tummies, our hypoallergenic Fresh Menu recipes are a good place to start.
How Much Should You Feed an Adult Chihuahua?
As a starting point, daily food is worked out as a percentage of body weight:
- Puppies up to 8 months: around 4% of body weight
- Adults (all adult Chihuahuas fall in the up-to-15kg group): around 2–3% of body weight
For example, a 2.5kg Chihuahua fed at 2% needs about 50g of food a day (2.5kg × 2% = 50g). Here's how that works across the typical weight range:
| Adult weight | Daily food at 2% | Daily food at 3% |
|---|---|---|
| 1.5kg | 30g | 45g |
| 2kg | 40g | 60g |
| 2.5kg (average) | 50g | 75g |
| 3kg | 60g | 90g |
Please note: these are guidelines for healthy, active, non-neutered dogs. Needs can vary by up to 50% depending on age, size and activity. Use your dog's body condition as the real guide and adjust portions up or down. Weighing food on kitchen scales is the easiest way to get portions right for a dog this small.
What Toys Are Best for a Chihuahua?
The best toys for a Chihuahua are sized for a tiny mouth: soft plush toys for comfort, light squeaky toys for their alert, feisty nature, gentle dental chews to help with tartar, and mini puzzle feeders to keep their sharp mind busy.
Good to know: Chihuahuas have delicate jaws and teeth, so avoid anything hard, heavy or made for larger breeds. Toys designed for toy breeds last better and are much kinder on their teeth.
Chihuahua FAQs
How much exercise does a Chihuahua need?
Most Chihuahuas need up to 30 minutes of gentle walking and play a day. Their needs are modest, but short daily walks still help with fitness, confidence and socialisation.
Are Chihuahuas good family dogs?
Chihuahuas can be devoted, characterful family dogs in the right home. Because of their tiny size and confident streak, they do best with older children, gentle handling and consistent training from an early age.
Are Chihuahuas good with children?
Chihuahuas are best suited to homes with older, gentle children. Their tiny size makes them easy to injure during rough play or if they're dropped, and they may snap if handled roughly.
Can a Chihuahua live in a flat?
Yes. Their tiny size and low exercise needs make Chihuahuas one of the best breeds for flat living.
Do Chihuahuas shed?
Yes, but not heavily. Smooth-coated Chihuahuas shed lightly all year, and long-coated Chihuahuas shed a little more during seasonal coat changes. A weekly brush keeps it under control.
Are Chihuahuas hypoallergenic?
No. Both smooth and long-coated Chihuahuas shed, so they are not hypoallergenic and are not a reliable choice for people with dog allergies.
How much grooming does a Chihuahua need?
Very little. Smooth-coated Chihuahuas need only an occasional brush, while long-coated Chihuahuas benefit from brushing a couple of times a week to prevent tangles. Regular tooth brushing is important for both.
Do Chihuahuas need a coat in winter?
Many do. Chihuahuas have little body fat and a fine coat, so they lose heat quickly. A well-fitting jumper or coat helps on cold or wet days, especially for smooth-coated dogs.
Why do Chihuahuas shake?
Chihuahuas often shake because they are cold, excited or nervous, and their small size means they lose body heat quickly. Shaking can also be a sign of low blood sugar or pain, so speak to your vet if it is frequent or comes with other symptoms.
Are Chihuahuas easy to train?
Chihuahuas are clever and can learn quickly, but they can be stubborn and are known for being slow to house-train. Short, reward-based sessions and a consistent routine from day one work best.
Do Chihuahuas bark a lot?
Many Chihuahuas are keen barkers, as they are alert and quick to announce visitors and noises. Early socialisation and consistent training help keep barking under control.
How long do Chihuahuas live?
Chihuahuas are one of the longest-lived dog breeds, typically living 14 to 16 years, and many reach their late teens with good care.
What health problems do Chihuahuas have?
Common health problems in Chihuahuas include patellar luxation (slipping kneecaps), dental crowding and heart conditions such as mitral valve disease. Many also have a molera, a soft spot on the skull, which needs care but is common in the breed. Regular vet checks are important.
Final Thoughts
Give a Chihuahua gentle handling, consistent training and plenty of warmth on cold days, and you'll have one of the most loyal and long-lived companions you could ask for.
