The Complete Chihuahua Guide

You didn’t land on the Chihuahua by accident. This is a breed people seek out, and for good reason. Bold and full of personality, deeply devoted to their person, and adaptable to almost any living situation, they’re a natural fit for singles, apartment dwellers, seniors, and anyone who wants a fiercely loyal companion in the smallest possible package who want a spirited, loving companion who will shadow your every move and make sure you never feel alone. Let’s dig in.

What are the characteristics of a Chihuahua?

Think you know what you’re getting into with a Chihuahua? These scores will either confirm your suspicions or give you something to think about. Either way, good to know now.

Training

Trait	Score	What does it mean?
Trainability	3 out of 5	Chihuahuas are smart and quick to pick up on patterns, but they are independent and strong-willed. Training requires patience, consistency, and high-value rewards
Obedience	3 out of 5	They will follow direction when engaged and motivated, but expect selective listening. Firm, consistent guidance from day one is important
Focus	2 out of 5	Easily distracted by their environment and prone to following their own agenda. Keep sessions very short and highly engaging
Stubbornness	4 out of 5	One of the more stubborn toy breeds. Chihuahuas have strong opinions and are not shy about expressing them. Positive reinforcement and patience go a long way

Friendliness

Trait	Score	What does it mean?
Good with family	4 out of 5	Deeply devoted to their family and thrives on closeness. Bonds form quickly and Chihuahuas tend to take their role as companion very seriously
Good with children	3 out of 5	Can be good with children but their small size makes them vulnerable to rough handling, and they may snap if startled or hurt. Best suited to households with older, respectful kids
Good with strangers	3 out of 5	Varies widely by individual. Some Chihuahuas are warm and sociable, others are reserved or wary with strangers. Early socialization is essential
Good with other dogs	3 out of 5	Can coexist with other dogs and pets, but their bold, terrier-like confidence means they will not back down from a confrontation even with much larger animals

Adaptability

Trait	Score	What does it mean?
Apartment living	5 out of 5	One of the best apartment dogs in the world. Small, relatively quiet when trained, and perfectly content in a compact space with minimal outdoor access
Cold weather	2 out of 5	Very sensitive to cold due to their small size and low body fat. A warm coat or sweater is a practical necessity in cool weather, not optional
Hot weather	3 out of 5	Better heat tolerance than many small breeds, but their size means they can overheat quickly. Avoid prolonged outdoor activity in hot or humid weather
Routine flexibility	4 out of 5	Highly adaptable to different living situations and routines. Their compact size and modest exercise needs make them one of the most flexible companions around
First time owner	3 out of 5	Manageable for first-time owners in terms of size and exercise, but their stubbornness, tendency to bark, and need for early socialization require patience and consistent training

Physical needs

Trait	Score	What does it mean?
Energy level	3 out of 5	Energetic and lively for their size, but their overall exercise needs are modest. Short bursts of play and a daily walk are enough to keep most Chihuahuas content
Endurance	2 out of 5	Limited stamina due to their tiny frame. Keep activity sessions short and watch for signs of fatigue, particularly in heat or cold
Exercise needs	2 out of 5	Around 20 to 30 minutes of daily exercise is plenty. A short walk and indoor play session covers most of what a Chihuahua needs
Mental stimulation	4 out of 5	Curious, alert, and busy-brained. Chihuahuas need mental stimulation to stay balanced, and without it they can develop anxiety, excessive barking, or destructive habits
Grooming needs	2 out of 5	Low grooming needs for smooth-coat varieties. Long-coat Chihuahuas require more frequent brushing to prevent tangles, but neither variety needs professional grooming regularly

Personality

Trait	Score	What does it mean?
Playfulness	3 out of 5	Playful and spirited, especially with people they trust. Chihuahuas enjoy interactive games and toys, though they are equally happy curled up in a lap
Affection	5 out of 5	Among the most affectionate breeds relative to their size. Chihuahuas bond intensely with their person and thrive on close physical contact
Loyalty	5 out of 5	Exceptionally loyal. Chihuahuas tend to pick a favorite person and devote themselves completely. That loyalty is one of the defining traits of the breed
Independence	2 out of 5	Low independence. Chihuahuas crave constant company and are prone to separation anxiety when left alone for extended periods
Alertness	5 out of 5	Highly alert and always tuned in to their environment. Among the best watchdogs in the toy group, they will sound the alarm loudly and without hesitation

Behavior

Trait	Score	What does it mean?
Barking tendency	4 out of 5	Chihuahuas are known barkers. Without consistent training, vocalization can become a significant habit. Early guidance helps, but some individuals are naturally more vocal than others
Digging tendency	2 out of 5	Not a strong digger. Some individuals may scratch or dig out of boredom or instinct, but it is not a defining trait of the breed
Chewing tendency	2 out of 5	Moderate chewing tendency, particularly in puppyhood. Providing appropriate toys and redirecting early helps establish good habits
Prey drive	2 out of 5	Low to moderate prey drive. Some Chihuahuas will chase small animals with surprising determination given their size, but most are more interested in their people than in wildlife
Guarding instincts	3 out of 5	Alert, vocal, and surprisingly bold for their size. Chihuahuas will guard their person and their space with considerable conviction, even if their follow-through is limited by their stature

What are common health issues of a Chihuahua?

Like all breeds, Chihuahuas are prone to certain health conditions. Here’s what to keep on your radar.

What are the recommended health tests for Chihuahuas? 

Your Chihuahua can’t tell you when something’s off. That’s what these tests are for. Here’s what vets typically recommend for them.

• Cardiac evaluation by a board-certified cardiologist or primary care vet (OFA, annually from age 1)
• ACVO ophthalmologist eye exam (OFA Eye Registry, annually from age 1)
• Patellar luxation evaluation (OFA, from age 1)
• Neuronal Ceroid Lipofuscinosis 7 (NCL7) DNA test (recommended by CCA via Embark)

Do Chihuahuas need pet insurance?

We’ll let the numbers do the talking, but spoiler: a lot of Chihuahua owners are really glad they had coverage.

Those numbers aren’t hypotheticals. They’re real claims from real Chihuahua owners in 2025.

The right pet insurance means you’re making decisions based on what your dog needs, not what you can afford.

With Lemonade, you can build a plan around your Chi specifically. Start with accident and illness coverage as your base, then add on what makes sense for your dog, things like physical therapy, dental illness, or behavioral treatment, and skip what doesn’t. Coverage applies to conditions that aren’t pre-existing (AKA, a condition that occurs after your policy is active and your waiting periods have passed), and you’ll know exactly what’s included before you commit. No fine print ambushes, no surprises at claim time.

And when you do need to file? You can do it in the app in minutes. No paperwork, no hold music, no waiting around.

Chihuahuas are worth protecting with proper coverage. Here’s how to do it right.

How much does pet insurance cost?

The cost of your premium is personal. It depends on your Chis age, your location, and what you add to your plan. That said, here’s a realistic look at what other Chihuahua owners pay with Lemonade:

History of the Chihuahua

The Chihuahua is one of the oldest and most historically complex dog breeds in the world, and its exact origins remain a matter of ongoing debate among historians and geneticists. The most widely accepted theory holds that the modern Chihuahua descends from the Techichi, a small, companion dog kept by the Toltec civilization in Mexico as far back as the 9th century. Carvings and artifacts depicting small dogs resembling the Chihuahua have been found at Tula, the ancient Toltec capital. When the Aztecs conquered the Toltecs in the 12th century, they absorbed the Techichi into their own culture, where the dogs held both spiritual and practical significance. Following the Spanish conquest in the 16th century, the breed largely disappeared from historical record. In the mid-19th century, small dogs matching the description of the modern Chihuahua were rediscovered in the Mexican state of Chihuahua, from which the breed takes its name. American tourists and travelers encountered them there and began bringing them back to the United States. Genetic studies published in 2013 confirm that the modern Chihuahua retains a small but measurable proportion of pre-Columbian indigenous dog ancestry, distinguishing it from most other modern breeds. The AKC officially registered its first Chihuahua, a dog named Midget, in 1904. By the late 20th century, the breed had become a pop culture icon, and today it remains one of the most recognized and widely owned toy breeds in the world.

Caring for a Chihuahua

Training

Training a Chihuahua takes patience, but it’s worth the effort. They are bold, stubborn, and prone to small dog syndrome, which means owners must be consistent and avoid letting unwanted behaviors slide due to their small size. Short, positive sessions with high-value treats and firm but gentle boundaries tends to work best, and getting started early makes a real difference.

Whether you’re starting from scratch or leveling up, these are worth the read.

Grooming

Chihuahuas have a smooth or long coat that requires low grooming. Weekly brushing for smooth coats, or 2 to 3 times per week for long coats, prevents tangles, and the occasional bath keeps them looking their best. Long-coated Chihuahuas benefit from occasional trimming around the ears and paws.

From nail trims to professional care, here’s everything you need to keep your Chi looking (and feeling) their best.

Exercise and mental stimulation

Chihuahuas have moderate energy levels and need 30 minutes of exercise each day to stay happy and healthy. Short brisk walks, indoor play sessions, and interactive puzzle games are all great ways to burn through that energy. But physical exercise is only half the picture. Chihuahuas are moderately intelligent dogs, and mental stimulation is just as important as the miles you put in. Without it, they become snappy, anxious, and prone to excessive barking and demanding behaviors. Puzzle toys, training sessions, and scent work are all solid ways to keep their brain engaged between walks.

Here’s how to build an exercise routine your Chihuahua will actually love.

Nutrition

Chihuahuas are small dogs with moderate energy, so they need a diet to match. Most adults do well on around 200 to 300 calories a day, spread across two meals. Depending on what you’re feeding them, expect to spend around $20 to $35 a month on food. Not the cheapest line item, but not the most expensive either.

What goes in the bowl is your call, and your vet’s. Kibble, raw, fresh, or a combination: there’s no single right answer. Focus on quality ingredients, the right portions for your dog’s age and activity level, and you’re most of the way there.

Chihuahua costs and adoption

What does it cost to bring home a Chihuahua?

Before your Chihuahua even sets a paw in your home, there are some one-time costs worth planning for. Here’s what to expect upfront.

Category	Cost Range	Details
Adoption (Reputable breeder)	$500-$1,500	Health testing, vaccinations, early socialization, pedigree

What does it cost to own a Chihuahua each year?

Once you’re past year one, ownership costs settle into a more predictable rhythm. Here’s what most Chihuahua owners spend annually, though keep in mind these numbers can vary quite a bit depending on where you live, your dog’s individual health needs, and the choices you make along the way.

Chihuahua puppies

Puppy veterinary needs

The first year matters a lot. What happens between 8 weeks and 12 months shapes who this dog becomes. Here’s what to focus on.

The first few months are the most important window for your puppy’s health. Core vaccines start at 6–8 weeks and continue through 16 weeks. After that, its annual boosters and routine screening as they grow into adults.

It’s a lot to keep track of. That’s why we made it easy.

Puppy socialization

Chihuahua puppies are bold, alert, and fiercely devoted to the people they love. That outsized confidence and an intensity of loyalty that is rare in any breed is part of what makes them an owner who takes training seriously, provides daily companionship, and understands the physical limits that come with a very small dog, and it’s also why early socialization matters so much.

Between 8 and 16 weeks, get them in front of as much variety as possible. Different people, animals, sounds, surfaces, and locations. Keep every experience positive. Puppy classes are great for this: supervised, controlled, and full of exactly the kind of novelty a Chihuahua brain needs to learn that the world is mostly fine.

Where are Chihuahua’s most popular in the United States?

Based on Lemonade’s own policyholder data, Chihuahuas are most popular in these five states. We’ve also thrown in a few things local pet owners should keep an eye on, so your pup can get out there and explore safely.

1. California

Foxtail grass is one of the sneakiest hazards for California dogs. The barbed seeds can embed in paws, ears, and noses from late spring through early fall, so check your dog after any outdoor time. Wildfire smoke is also a real seasonal concern; when air quality alerts are in effect, it's best to keep walks short and stay indoors as much as possible.

2. Texas

Texas heat is intense and sets in early. Hot pavement can burn paws from late spring through early fall, and heatstroke risk is high during midday walks in cities like Houston, Dallas, and San Antonio. Rattlesnakes, scorpions, and fire ants are also common hazards, particularly in suburban and rural areas.

3. Florida

Florida's heat and humidity make heatstroke a real risk, especially in summer. Keep walks to cooler parts of the day and always bring water. Blue-green algae blooms in freshwater lakes and ponds can also be toxic to dogs, so it's best to keep pups out of standing or slow-moving water, particularly from late summer into fall.

4. New York

In New York City, street hazards are the main thing to watch. Dropped food, discarded gum containing xylitol, and litter are common ingestion risks on sidewalks and in parks. Upstate and in Long Island, the story shifts to ticks: New York is a Lyme disease hotspot, and black-legged ticks are active from early spring through late fall.

5. Arizona

The desert heat is the biggest thing to watch year-round. Pavement in Phoenix can reach dangerous temperatures in summer, so early morning or evening walks are best for your dog's paws. Arizona is also home to rattlesnakes, scorpions, and desert toads, all of which are more active in warmer months, so stay alert on trails and in the yard.
