¶Quick Facts
The Chihuahua is a Mexican companion dog and the smallest recognized dog breed in the world. It is small enough to accompany its owner almost anywhere, but it still needs training, exercise, and opportunities to use its nose and mind like other dogs.
- Origin: Mexico
- Purpose: companion dog in FCI Group 9
- Weight according to the breed standard: 1–3 kg, with 1.5–2.5 kg as the ideal weight
- Height at the withers: the breed standard gives no height range; the Chihuahua is judged by weight
- Coat: smooth or long
- Breed-typical temperament: quick, alert, lively, and very courageous
- Important health checks: knees, teeth, bite, eyes, and the fontanelle of the skull
“Teacup”, “mini”, and similar terms are not recognized sizes or separate varieties of Chihuahua. There is only one weight standard and two coat varieties. Under the breed standard, a weight below 1 kg or above 3 kg is a disqualifying fault. An unusually small dog still belongs to the same breed, and low weight is not in itself proof of quality or good health.
¶Appearance & Coat
The Chihuahua should be compact and slightly longer than tall, with an apple-shaped head, large upright ears, and a high-carried tail. The expression should be alert, but the eyes should not protrude and the muzzle must not be excessively short.
The smooth-coated variety has a short, soft, glossy coat that lies close to the body. The long-coated variety has a fine, silky coat that is flat or slightly wavy, with longer hair on areas including the ears, neck, legs, and tail. A long coat should therefore not be heavy or excessively flowing; an overly abundant coat is not typical of the breed.
Coat care is generally straightforward. Bathe the dog when dirty and comb the long-coated variety about once a week, paying particular attention behind the ears and to the longer feathering. The smooth coat can be brushed as needed. Use the same routine to accustom the dog to having its nails, teeth, ears, and eyes checked.
All colours and colour combinations are allowed except merle. Merle is therefore not a rare accepted Chihuahua colour but is expressly excluded by the international breed standard.
¶Temperament & Personality
A breed-typical Chihuahua is quick to react, alert, lively, and courageous. It may readily signal when something happens around the home, but fear, aggression, or continuous barking should not be described as inevitable breed traits. The current breed standard accepts neither aggression nor extreme shyness.
Many individuals form close bonds with their family and are attentive to unfamiliar people, sounds, and dogs. How this is expressed is influenced by heredity, early experiences, health, and what the dog has learned. A Chihuahua that is always carried away gets fewer opportunities to practise calm encounters and move through different environments. At the same time, such a small dog should not be forced to greet others or endure intrusive play in an attempt to “socialize” it. Good socialization means brief, safe experiences in which the dog can keep its distance and recover.
The breed can suit a first-time owner who wants to teach everyday skills and takes its small size seriously. It is less suitable for someone seeking an accessory or assuming that a small body automatically means little responsibility.
¶Training & Exercise
The Chihuahua needs daily movement and mental activity, but no single number of minutes suits every dog. Age, fitness, surface, weather, and recovery are better guides than a generic walking schedule. A healthy adult Chihuahua can enjoy walks, scent work, tricks, everyday obedience, and suitably adapted dog sports.
Train progressively with reward-based methods. Prioritize recall, lead manners, calm handling, and teaching the dog to stop barking and settle. Short sessions can be practical, but finish according to the dog's concentration rather than after a fixed number of minutes. The same kind, consistent rules should apply to a small dog as to a large one.
A Chihuahua should normally be allowed to walk rather than be carried, so that it gets the exercise and experience of different environments it needs. Carrying the dog is sensible in crowds, where there is a risk of injury, or when it genuinely needs help, but it should not replace exercise. Puppies need more breaks and a gradual increase in physical demands; an adult dog that suddenly refuses to walk or becomes lame should be examined rather than simply carried onward.
¶Health
The most useful health checks for a Chihuahua concern the knees, mouth and teeth, and a head shape without exaggeration. A long list of possible diagnoses is less helpful than knowing what to check in the parents, puppy, and adult dog.
- Patellar luxation: The kneecap can slip out of its normal position, and lameness or an abnormal gait may be signs. For a litter to be registered with the Swedish Kennel Club, both parents must have an official patella result from an examination performed at the age of at least one year and before mating. Ask to see the results in the Swedish Kennel Club register and always check which rules apply at the time of purchase.
- Teeth: A British study of veterinary records found periodontal disease and retained deciduous teeth among the most commonly recorded problems in Chihuahuas. Accustom the puppy to daily toothbrushing and watch closely as the adult teeth come in. If a deciduous tooth remains when the permanent tooth erupts beside it, the mouth should be assessed by a veterinarian.
- Head and eyes: The Swedish Kennel Club's breed-specific instructions for judges highlight risks associated with excessive dwarfism, an overly short muzzle, incorrect bite or jaw, and overly prominent eyes. Do not ask only about an “apple head”; look for a functional bite, a muzzle without exaggeration, and eyes that do not bulge.
- Fontanelle: An open fontanelle, sometimes called a molera, is not a desirable feature. It is a disqualifying fault under the current breed standard. A small depression after the fontanelle has closed is different and is not disqualifying. A puppy or adult dog with a suspected opening should be assessed by a veterinarian.
Also monitor body condition and movement. Sudden lameness, eye pain, or difficulty eating should be taken seriously.
¶History & Origins
Mexico is the Chihuahua's official country of origin, and the breed takes its name from the Mexican state of Chihuahua. This is well established, but the exact path to the modern dog is less well documented.
The official breed standard recounts a tradition that small dogs may have lived in the region during the time of the Toltecs. Depictions of dogs called Techichi at Tula resemble the modern Chihuahua. The standard presents this as an assumption, not as proof of an unbroken lineage. Stories about a specific ancient ancestor or a particular cross should therefore be described as theories rather than established history.
¶Living with the Breed
The Chihuahua can thrive in an apartment, a family with children, or a home with other animals when daily life is arranged appropriately. The size of the home matters less than regular time outdoors, training, rest, and avoiding situations in which its small body is at risk of injury.
An adult should always be present around young children. Children need to learn to leave the dog undisturbed in its resting place and not to lift, carry, or chase it. This does not mean that the breed “dislikes children”; it is a practical safety rule for a dog weighing only a few kilograms.
Compatibility with dogs and cats depends on the individuals, not just the breed name. Let two dogs meet calmly in neutral territory and interrupt play that becomes too physical. When introducing a cat, a gate, separate resting places, and protected feeding areas are useful. The difference in size matters: even friendly play with a much larger dog can injure a Chihuahua, so interactions need supervision.
Alone-time should be introduced gradually once the dog feels secure in the home. A young puppy cannot be left alone, and adult dogs vary in what they tolerate. Use the dog's behaviour as your guide instead of assuming that every Chihuahua develops separation anxiety or can cope for the same length of time.
In cold, windy, or wet weather, an individual may need a well-fitting dog coat, but there is no meaningful temperature threshold that applies to every dog. Adapt to coat variety, age, health, activity, and the dog's own signs of discomfort. The best daily life therefore combines care for a very small body with the expectation that the Chihuahua should be allowed to live as a dog.

¶Frequently Asked Questions
Are Chihuahuas good family dogs or are they better for single owners?
They can live happily in families, but they are usually best suited to calm households with older, respectful children. Because of their tiny size and tendency to bond closely with one person, rough handling or chaotic environments can easily stress them and lead to nipping or nervous behavior.
Why do Chihuahuas shake so much, and is it always a health problem?
Trembling is very common in this breed and often relates to excitement, anxiety, or feeling cold because of their small body and low fat reserves. However, persistent shaking, weakness, or collapse can signal low blood sugar, pain, or a neurological issue, so any change from your dog’s normal pattern should be checked by a vet.
How much exercise does a Chihuahua really need considering its size?
Most do well with two or three short walks a day plus some indoor play, adding up to around 30 to 45 minutes of gentle activity. They are small but often energetic, so regular mental stimulation with training or games is just as important as physical exercise.
What health problems are Chihuahuas most prone to?
Common issues include dental disease, luxating patella (loose kneecaps), heart problems such as mitral valve disease, and eye conditions. They may also be at risk for tracheal collapse and low blood sugar in very small individuals, so routine vet care and careful monitoring of breathing, mobility, and eating habits are important.
Are Chihuahuas hard to house train compared with other dogs?
They have a reputation for being slower to house train, partly because their tiny size makes accidents easy to overlook and they can be sensitive to bad weather. Consistent routines, frequent outdoor trips, and positive reinforcement from the first day home usually make training much more successful.
Do Chihuahuas bark a lot, and can their barking be controlled?
Many are naturally vocal watchdogs that alert to small noises and movement. Early training to teach a quiet cue, combined with good socialization and enough mental stimulation, can significantly reduce nuisance barking, although some level of alertness is typical for the breed.
What special care do Chihuahuas need because of their tiny size?
They are vulnerable to injury from falls, being stepped on, or jumping off furniture, so they need a carefully managed environment and supervision around larger pets and children. Owners should also watch for rapid drops in blood sugar in very small or young dogs and protect them from cold with appropriate clothing and warm bedding.
How do long-haired and smooth-coated Chihuahuas differ in grooming needs?
Smooth coats need minimal grooming, usually a weekly brush and occasional bath. Long-haired dogs require more frequent brushing to prevent tangles and may need extra attention around the ears, tail, and trousers, but both coat types shed moderately rather than heavily.
Are Chihuahuas suitable for apartment living and urban environments?
Their small size and relatively low exercise needs make them very compatible with apartment life. The main challenges in cities are noise sensitivity and barking, so good socialization to sounds, people, and elevators or stairwells is important from an early age.
Is it safe for Chihuahuas to live with bigger dogs or other pets?
They can live peacefully with larger dogs and other animals if all pets have steady temperaments and interactions are closely supervised. The main risk is accidental injury to the smaller dog, so jumping, rough play, and unsupervised time together should be carefully managed.¶Comparisons with other breeds
