Chihuahua Breed Guide – Temperament, Size, Care & Puppy Essentials

Chihuahuas may be the smallest recognised dog breed, but they are anything but insignificant. Bright, affectionate and often remarkably confident, they tend to form very close bonds with their people and can make wonderful companions for the right home.
This guide covers the practical things new owners usually want to know: adult size, temperament, exercise, grooming, training, health considerations, crate size and the puppy essentials that suit this very small breed.

What Is a Chihuahua Like?
Chihuahuas are often described as alert, lively, affectionate and full of character. Many become deeply attached to one or two people and like to stay close to them throughout the day. They can be wonderfully cuddly, but they are still real dogs with a need for training, exercise, sniffing, play and mental stimulation.
Their tiny size can sometimes cause owners to treat them differently from larger dogs. A Chihuahua still benefits from calm boundaries, positive-reinforcement training and early exposure to everyday sights, sounds, people and well-mannered dogs.
Are Chihuahuas Good Family Dogs?
They can be excellent family companions, but their small size means handling matters. They are generally better suited to children who are old enough to understand that a tiny dog should not be grabbed, carried around or disturbed while sleeping.
As with any breed, temperament varies from dog to dog. Good early socialisation and respectful handling are more useful than assuming every Chihuahua will behave in the same way.
Are Chihuahuas Easy to Train?
Chihuahuas are intelligent and can learn quickly, particularly when training is consistent and reward-based. Short sessions usually work best.
- Start recall and name recognition early.
- Reward calm behaviour around visitors and other dogs.
- Introduce alone-time gradually rather than suddenly.
- Use tiny treats so training rewards do not add excessive calories.
- Do not allow unwanted behaviour simply because the dog is small.
Some Chihuahuas are naturally vocal. Teaching a calm settle, rewarding quiet behaviour and avoiding accidental reinforcement of barking can make a big difference.
How Much Exercise Does a Chihuahua Need?
Despite their size, Chihuahuas are active little dogs. For many healthy adults, around 30 minutes of exercise a day, divided into shorter walks, is a useful starting point. Puppies, seniors and dogs with health conditions need individual adjustments.
Sniffing walks, short training sessions and indoor games are all valuable. Very young puppies should not be pushed into long walks simply to “wear them out”. Build activity gradually and follow your vet’s advice if you are unsure.
Do Chihuahuas Get Cold?
Very small dogs can lose body heat quickly, and short-coated Chihuahuas in particular may feel cold in damp, windy or winter weather. A well-fitted coat can make outdoor trips more comfortable, but the dog should still be able to move freely without rubbing or restriction.
Smooth Coat vs Long Coat Chihuahua
Both varieties have the same basic breed needs, but coat care differs slightly.
- Smooth Coat: usually benefits from a gentle weekly brush to remove loose hair.
- Long Coat: usually needs brushing several times a week, with extra attention behind the ears, under the legs and around the feathering.
Chihuahuas do shed, so descriptions such as “non-shedding” or “hypoallergenic” should not be assumed to apply to the breed.
Chihuahua Health Considerations
Chihuahuas can live long, healthy lives, but responsible owners should be aware of breed-related risks. Conditions that may be seen include luxating patellas and certain eye or neurological concerns. Their very small mouths also mean dental care deserves particular attention.
If you are buying a puppy, ask the breeder what health screening has been carried out on the parents and discuss any breed-specific testing recommended by reputable breed organisations. Regular veterinary checks, keeping your dog lean and maintaining good dental care are all important.
Important: online breed guides are useful for general information, but they cannot replace advice from your vet for your individual dog.
What Size Crate Is Best for a Chihuahua?
For many Chihuahuas, a 24-inch crate gives enough space to stand, turn around and lie down comfortably while still creating a snug sleeping area. Very tiny puppies may benefit from using a divider or keeping the sleeping zone compact during early crate training.
A crate should never be used as punishment. Introduce it positively with bedding, treats and short calm sessions, and build up duration gradually.

Creating a Calm Sleep Space

Are Puppy Carriers Useful for Chihuahuas?
They can be very useful, particularly for very young puppies, busy environments, public transport or occasions when little legs have had enough. A carrier should support the dog properly, allow ventilation and always be used with a secure internal safety attachment designed for a harness rather than the neck.
A carrier is not a substitute for exercise or socialisation. The aim is to give your Chihuahua a safe rest option while still allowing them to experience the world.

Harness or Collar for a Chihuahua?
A lightweight, well-fitted harness can be useful for walks because it avoids concentrating lead pressure directly on the neck. Fit matters more than size labels: the harness should be secure without rubbing the shoulders or restricting movement.
A collar can still be useful for an ID tag, but many owners prefer to attach the lead to a harness for everyday walks.
Feeding a Chihuahua
Because Chihuahuas are so small, generic advice such as “feed half a cup a day” is not reliable. Calorie needs depend on the dog’s age, body condition, activity level and the energy density of the food.
Use the feeding guide for a complete, balanced food as a starting point, then adjust with your vet if necessary. Keep treats small and include training rewards in the dog’s daily calorie allowance.
Dental Care
Dental care is especially important in toy breeds because small jaws can become crowded. Introduce tooth brushing gradually with dog-safe toothpaste and ask your vet to check the teeth at routine appointments.

Chihuahua FAQs
How big does a Chihuahua get?
Many healthy adults weigh around 1.8–2.7kg, although individuals vary. Size alone should never be used to judge health — body condition and veterinary assessment matter more.
How much exercise does a Chihuahua need?
Around 30 minutes a day is a useful general guide for many healthy adults, often divided into shorter walks, plus play and mental stimulation.
Can Chihuahuas live in apartments?
Yes. Their small size suits compact homes well, provided they still receive daily exercise, enrichment, training and company.
Are Chihuahuas good with children?
They can be, especially with older children who understand gentle handling. Because Chihuahuas are physically small and delicate, supervision is important.
Do Chihuahuas bark a lot?
Some are naturally alert and vocal. Early socialisation, consistent training and rewarding calm behaviour can help prevent excessive barking from becoming a habit.
What size crate does a Chihuahua need?
A 24-inch crate is suitable for many adult Chihuahuas and gives enough room to stand, turn and stretch. Very tiny puppies may need a divider or a smaller sleeping area during early training.
Do Chihuahuas need coats in winter?
Many do appreciate extra warmth in cold, wet or windy weather, particularly Smooth Coat Chihuahuas and very small individuals. Choose a coat that fits properly and does not restrict movement.
Is a Chihuahua Right for You?
A Chihuahua can be a brilliant companion for someone who wants a very small dog with a big personality. They tend to thrive in homes where they are included in daily life, given kind but consistent training and protected from rough handling.
Choose the breed because you enjoy the Chihuahua temperament — not simply because of their tiny size. With thoughtful socialisation, sensible exercise, good dental and veterinary care and a secure home routine, they can be affectionate and entertaining companions for many years.
