Chihuahua: Temperament, Lifespan & Care Guide

Vet verified. Written by Danielle Montgomery, Copywriter. Reviewed by Dr. Linda Simon MVB MRCVS, Team Vet.

The Chihuahua may be tiny, but this dog is rarely short on confidence. Alert, adaptable, affectionate with familiar people, and often delightfully opinionated, Chihuahuas can thrive in apartments or larger homes when their physical safety, training, and social needs are taken seriously.

This guide covers the whole picture: Chihuahua size and lifespan, temperament, exercise, grooming, common health concerns, family fit, and how to identify a responsible breeder or rescue.

This guide covers health testing, measurements, weather, cost questions and product placement for American owners. The goal is not to make a tiny dog sound easy. It is to show what safe, respectful Chihuahua ownership actually requires.

Small size changes risk. A fall from a couch, an accidental kick, rough play with a large dog or a calorie surplus that looks trivial can have a major effect. At the same time, Chihuahuas need real walking, training, enrichment and choice. Protecting them should not mean preventing them from being dogs.

Chihuahua quick facts

Chihuahua coat types, head descriptions and colors

Smooth-coat Chihuahua

The smooth variety has a close glossy coat with longer hair possible around the neck and tail. It still sheds and needs brushing, nail care, dental care and weather protection. Short hair does not make the dog resistant to cold.

Long-coat Chihuahua

The long variety has soft feathering around the ears, neck, legs and tail. Texture and amount vary. Check behind the ears, under the harness, in the armpits and around the tail for tangles. The two coat varieties belong to the same breed and should meet the same health priorities.

Apple head and deer head

The AKC standard describes a rounded apple-dome skull. “Deer head” is an informal appearance label, not a separate breed or registered variety. Head shape does not replace health evidence. Evaluate teeth, eyes, breathing, molera, movement and parental screening instead of buying a marketing label.

Chihuahua colors

Many colors and markings occur. Color should never outrank temperament, structure, health testing and functional size. Merle requires careful pedigree and genetic discussion, and color-linked claims should be verified rather than accepted from advertising.

Chihuahua temperament and personality

Chihuahuas are often confident, observant, bright, and deeply attached to their chosen people. Many enjoy being close to their family and make keen little watchdogs. That alertness can turn into frequent barking or suspicion of unfamiliar people when owners skip calm, reward-based socialization.

Treat a Chihuahua like a dog, not an accessory. They benefit from learning polite greetings, recall, settling on a mat, cooperative handling, and comfortable alone time. Picking up a nervous dog every time something new appears can accidentally confirm that the situation is dangerous. Give them distance, pair new experiences with rewards, and let confidence grow at the dog's pace.

Common Chihuahua personality traits

• Alert: many notice hallway sounds, visitors and environmental changes quickly.
• Loyal: close bonds may form with one or several people.
• Bright: they learn patterns and can repeat whatever has earned attention.
• Energetic: short bursts of play and exploration are common.
• Sensitive: harsh handling can increase fear and defensive behavior.
• Independent: motivation and clarity matter more than physical pressure.

“Small dog syndrome” is not a diagnosis

The phrase often blames the dog for barking, guarding or snapping while overlooking fear, pain, inconsistent boundaries and repeated forced handling. Use the same respectful standards applied to a larger dog: prevent unsafe rehearsal, teach alternatives, honor warning signals and investigate medical causes.

Can a Chihuahua be left alone?

An adult can learn reasonable alone periods, but the skill should be built gradually. Begin with seconds behind a gate while the dog remains relaxed. Use a camera for longer trials. A crate is not safe if the dog panics, overheats or injures itself trying to escape.

Prolonged barking, drooling, frantic scratching, destruction, house soiling or refusal of a normally valuable food toy can indicate separation-related distress. Ask a veterinarian to rule out pain and medical problems, then seek a qualified reward-based behavior professional.

Are Chihuahuas good family dogs?

They can be loving family companions in a household that understands their size. A Chihuahua's small frame makes accidental falls, rough handling, and collisions with larger dogs more consequential. Homes with calm older children who can follow dog-safety rules are often a better fit than homes with very young children.

Every interaction between a child and dog should be supervised. Give the Chihuahua a quiet bed or crate where nobody follows them, and teach children never to lift, chase, hug, or disturb a sleeping or eating dog.

Active supervision means an adult is watching closely enough to intervene. Turning away, lip licking, whale eye, freezing, hiding and growling are reasons to create space. Do not punish a growl. It gives the family a chance to change the situation before a bite.

Can Chihuahuas live with other pets?

Many live happily with other dogs and cats after careful introductions. Match play styles and supervise around much larger dogs: even friendly rough play can cause injury. Resource guarding, barking, or chasing should be addressed early with a qualified reward-based trainer.

Use gates, parallel walks and brief sessions. Give cats high escape routes and feed animals separately. Rabbits, rodents and birds should remain securely separated. Friendly behavior does not eliminate accidental-injury or predatory risk.

Exercise and enrichment

Small does not mean sedentary. Most healthy adult Chihuahuas enjoy short daily walks, sniffing time, gentle games, and training sessions. The right amount depends on age, body condition, weather, and health. Build fitness gradually and stop if your dog limps, lags, coughs, or seems distressed.

Because of their small body mass, Chihuahuas can become cold quickly. A well-fitting coat may help in cold weather. In hot weather, walk during cooler hours and test pavement before letting any dog cross it. Puzzle feeders, scent games, and five-minute training sessions provide useful mental exercise without requiring a long route.

Many healthy adults enjoy around 30 minutes of total walking and play across the day, but the clock is not a prescription. Age, knees, heart, trachea, weather and individual fitness determine the safe amount. Short legs still cover real distance, and carrying should not replace all movement.

A practical daily activity pattern

• One or two short sniff walks at the dog's pace
• Frequent bathroom trips, especially for puppies and seniors
• Brief reward-based training
• Indoor search games and puzzle feeding
• Gentle play on nonslip flooring
• Planned rest in a warm secure space

Cold-weather safety

Watch for shivering, lifting paws, slowing, hunching or seeking shelter. Use a fitted coat that does not restrict shoulders or toilet posture. Avoid salt and deicing chemicals, rinse paws after exposure and shorten the route in severe cold. A sweater is not permission for prolonged exposure.

Hot-weather safety

Tiny size does not prevent heatstroke. Check air, humidity, direct sun and pavement, choose cooler hours and carry water. Stop for heavy panting, weakness, vomiting, confusion, abnormal gums or collapse. Read the US hot-weather walking guide.

Prevent jumps and falls

Use a stable ramp or low steps for furniture, add nonslip rugs and block open staircases. Do not place a Chihuahua on a high surface unattended. Lift by supporting chest and hindquarters, never by the front legs, collar or scruff.

How to train a Chihuahua

Use the same clear, kind standards you would use with a larger dog. Reward the behavior you want, prevent rehearsal of unwanted behavior, and keep sessions brief. Harsh corrections can increase fear and defensive behavior.

• House training: Offer frequent outdoor breaks, reward immediately, and supervise closely. Tiny bladders and bad weather can make consistency especially important.
• Handling: Pair gentle touches to paws, ears, mouth, and harness with small treats so grooming and veterinary care feel predictable.
• Barking: Reduce triggers where possible, teach a calm alternative, and reward quiet check-ins rather than shouting over the dog.
• Recall: Practice indoors and on a long line before relying on it outside. A Chihuahua can still run into traffic or wildlife danger.

Use management first

Block gaps in railings, store unsafe food and use gates near doors. Keep large dogs separated during exciting arrivals. Management prevents dangerous rehearsal while cues are being learned. It is especially important when a single mistake can cause a fall or escape.

Find appropriately tiny rewards

Cut soft rewards smaller than a pea and subtract them from daily calories. Praise, toys, sniffing and access to a favorite bed can also reinforce behavior. If a normally food-motivated Chihuahua suddenly refuses rewards, consider fear, dental pain, nausea, cold or illness.

Harness training

Reward approaching the harness, placing the nose through and tolerating one clip at a time. Check that a Y-front design clears the throat and shoulders and does not rub behind the legs. Recheck fit often in puppies and very small dogs.

Recall and door safety

Begin indoors, say the cue once and move away. Reward arrival generously. Progress to a fenced area and long line. Never test an unfinished recall near traffic or wildlife. Teach waiting behind a boundary while exterior doors open.

Housetraining

Offer frequent outdoor breaks after waking, eating, drinking, play and training. Use a covered area during bad weather if needed and reward immediately outdoors. Clean accidents with an enzymatic product. Sudden regression can reflect urinary, digestive, mobility or cognitive disease.

Calm visitor training

Use distance, a gate and scattered food to keep arousal manageable. Ask visitors to ignore the dog initially. Reward looking at the visitor and returning attention to the owner. Do not pass a fearful Chihuahua from person to person.

When behavior needs medical assessment

Reluctance to jump may reflect patella or spinal pain. Avoiding a collar can signal tracheal discomfort. Snapping during mouth handling may indicate dental disease. New irritability deserves a physical explanation before stronger training pressure.

Chihuahua grooming and dental care

Smooth-coated Chihuahuas usually need occasional brushing. Long-coated dogs benefit from more frequent brushing, especially behind the ears, under the legs, and around the tail. Keep nails short enough that they do not alter the dog's gait, check ears, and use a veterinarian-approved parasite-prevention plan.

Dental care deserves special attention in small dogs. Brush daily with dog toothpaste when possible and ask your veterinarian to assess the mouth at routine visits. Finch & Barker's dog dental-care collection can support an at-home routine, but sprays and chews do not replace brushing or professional veterinary treatment when dental disease is present.

Smooth-coat grooming

Use a soft rubber tool or bristle brush weekly to remove loose hair and inspect the skin. Bathe when dirty with dog shampoo and dry completely. Sudden hair loss, dandruff, sores or intense itching is not routine shedding.

Long-coat grooming

Comb feathering several times a week, especially behind the ears, under the harness, in the armpits and around the tail. Work from the ends toward the skin without pulling. Severe mats may need professional clipping for welfare.

Nails and paws

Trim or grind nails frequently enough to preserve grip. Tiny nails still contain a quick, so remove small amounts and ask a professional to demonstrate. Check between toes for redness, swelling, debris or persistent licking.

Ear and eye checks

Look for ear redness, odor, discharge or pain and use only a veterinary-approved cleaner. Do not push cotton swabs into the canal. Squinting, cloudiness, sudden tearing, rubbing or holding an eye closed deserves same-day advice.

Dental care step by step

1. Teach a relaxed chin rest or one-second lip lift.
2. Introduce dog toothpaste on a finger or soft cloth.
3. Add a pet toothbrush gradually without forcing the mouth open.
4. Focus on outer tooth surfaces where plaque accumulates.
5. Stop for pain, bleeding or strong avoidance and book an examination.

Human toothpaste can contain unsafe ingredients. Home scraping can fracture enamel, injure gums and miss disease below the gumline. Read how to manage plaque without unsafe scraping.

Chihuahua health and lifespan

The American Kennel Club lists an average Chihuahua lifespan of roughly 15–17 years. Good breeding, preventive veterinary care, healthy body condition, dental care, safe exercise, and prompt treatment all matter, but no lifespan can be promised.

Health concerns seen in the breed can include:

• Patellar luxation: the kneecap moves out of its normal groove, sometimes causing skipping, pain, or arthritis.
• Heart disease: small dogs can develop degenerative mitral valve disease; a murmur may be found during an examination.
• Eye disease: prominent eyes can be vulnerable to injury as well as inherited conditions.
• Dental disease: crowded teeth and plaque can contribute to painful periodontal disease.
• Tracheal problems: coughing or breathing changes need veterinary assessment; use a well-fitted harness if your veterinarian recommends one.
• Low blood sugar in very small puppies: weakness, shaking, disorientation, or collapse is an emergency.

The Chihuahua Club of America recommends patella, cardiac, and ophthalmologist evaluations for breeding dogs. Ask a breeder for verifiable results, not just the phrase “vet checked.” A CHIC number shows that required tests were completed and made public; it does not by itself mean every result was normal.

Patellar luxation

A kneecap that moves out of its groove can cause skipping, lameness, pain and later arthritis. Some dogs carry a leg briefly and return to normal; that pattern still deserves assessment. Management depends on grade, symptoms, alignment and age and may include weight control, rehabilitation or surgery.

Cardiac disease

Degenerative mitral valve disease is important in small older dogs, while congenital disease can affect younger animals. A murmur is a finding, not a complete diagnosis. Further evaluation may include chest imaging, blood pressure, electrocardiography or echocardiography. Coughing, rapid breathing at rest, weakness, collapse or a swollen abdomen needs prompt care.

Eye disease

Inherited disease, dry eye, cataracts, glaucoma and injury can affect vision and comfort. A board-certified ophthalmologist examination is one of the three CCA tests. Squinting, sudden cloudiness, an enlarged eye, marked redness or holding an eye closed is urgent.

Dental disease

A tiny jaw can leave teeth crowded, rotated or retained. Plaque below the gumline can cause pain, infection and bone loss even when the visible crowns look acceptable. Daily brushing and regular veterinary assessment are essential.

Tracheal collapse and airway concerns

A collapsing trachea can produce a dry honking cough, especially with excitement or pressure on the neck. Similar signs can come from heart, airway or infectious disease, so coughing needs diagnosis. Use a fitted harness when advised and avoid smoke and overheating.

As of April 2026, Chihuahuas are eligible for the OFA Respiratory Function Grading Scheme. The scheme was developed around BOAS and adds functional breathing information before and after controlled exercise. It does not replace cardiac or tracheal evaluation.

Hypoglycemia in puppies

Very young, very small or ill puppies have limited energy reserves. Weakness, trembling, disorientation, unusual sleepiness, seizures or collapse is an emergency. Follow the breeder and veterinarian's feeding plan and do not attempt to manage recurrent episodes with internet remedies.

Molera and head safety

A molera is a soft opening between skull bones that may be present in Chihuahua puppies and can persist. It is not proof of hydrocephalus, but careful handling and veterinary assessment matter. Prevent falls and impact. A domed head with neurologic signs needs investigation.

Hydrocephalus and neurologic signs

Hydrocephalus involves abnormal cerebrospinal fluid accumulation and can cause behavior change, poor coordination, seizures, vision problems or developmental concerns. Head shape alone does not diagnose it. Neurologic examination and imaging guide care.

Legg-Calvé-Perthes disease

This hip disorder can affect young toy-breed dogs when blood supply to the femoral head is disrupted. Progressive hind-limb pain, muscle loss and lameness needs imaging. Treatment may include surgery and rehabilitation.

Obesity

A few ounces can be a meaningful percentage of a Chihuahua's body weight. Excess fat adds stress to knees, breathing and heart. Ask for a body condition score and adjust calories before a small daily surplus becomes a chronic problem.

Chihuahua health testing in the United States

The Chihuahua Club of America identifies three core tests for its OFA CHIC protocol:

1. Patella evaluation. A veterinarian assesses kneecap stability after the required age.
2. Cardiac examination. Screening looks for evidence of congenital or early cardiac disease within the protocol.
3. Ophthalmologist evaluation. A board-certified ACVO ophthalmologist examines the eyes for inherited and structural disease.

A CHIC number means the required testing was completed and released publicly. It does not guarantee normal results or a healthy puppy. Open the OFA record and read each result, date, age and identity. Ask about molera, dental health, trachea, Legg-Calvé-Perthes, seizures and longevity in relatives even when no formal screen exists.

How to verify breeder claims

1. Request registered names and permanent identification for both parents.
2. Search OFA yourself instead of relying on cropped screenshots.
3. Confirm cardiac, patella and ophthalmologist results.
4. Read outcomes rather than treating the CHIC number as a pass badge.
5. Ask about adult relatives, not only the immediate parents.
6. Discuss teeth, heart, knees, trachea, eyes, neurologic disease and lifespan.
7. Choose a breeder who takes a dog back at any age.

What is a “teacup” Chihuahua?

“Teacup” is not a separate AKC-recognized Chihuahua variety. It is a marketing term commonly used for an exceptionally small dog. Selecting for extreme miniaturization can increase the risks associated with fragile bones, low blood sugar, dental crowding, and other problems. Avoid sellers who make size guarantees, price puppies primarily by tiny size, or dismiss health testing.

The AKC standard already caps weight at six pounds. There is no health-based need to create a smaller category. A buyer should ask about stable blood sugar, ability to eat normally, skull, dentition, knees, heart, eyes and adult relatives rather than chasing the lowest projected number.

Food and nutrition

Feed a complete and balanced diet appropriate for your Chihuahua's life stage. Measure portions and count training treats; a small calorie surplus is significant in a six-pound dog. Your veterinarian can show you how to monitor body condition beneath the coat and adjust intake after neutering, illness, or activity changes.

If you are considering a wellness product, browse our dog supplements and share the ingredient panel with your veterinarian. Supplements should complement an appropriate diet and care plan, not treat an undiagnosed symptom.

There is no universal best Chihuahua food. Choose a complete and balanced formula for life stage, then adjust calories to the individual. Kibble size can affect handling, but a “small breed” label does not automatically make one formula medically superior.

How much should a Chihuahua eat?

Start with calorie information and the feeding guide, then adjust using weight trend and body condition. Weighing food in grams improves accuracy. A rounded tablespoon or extra treat can be a large percentage of a six-pound dog's day.

Meal frequency

Healthy adults may do well on two or more measured meals, while puppies often need more frequent feeding based on age, size and veterinary guidance. The source guide suggests three adult meals as one approach, but the correct schedule is individual. Recurrent weakness or trembling is not solved by casually adding sugar; it needs diagnosis.

Body condition

Ribs should be easy to feel beneath a light layer, with a waist visible from above. A long coat can hide outline, so use hands. Weight loss should protect muscle through a calorie-controlled complete diet, accurate portions and safe movement.

Training treats

Use crumbs smaller than a pea and put the daily allowance in a container each morning. Some regular food can become rewards. Avoid cooked bones, chocolate, grapes, raisins, onion, garlic, macadamia nuts and products containing xylitol.

Food allergy claims

Itching, ear disease, paw licking and digestive signs are not proof of food allergy. A diagnostic elimination trial uses a prescribed novel-protein or hydrolyzed diet exclusively and may be followed by challenge. Flavored medication and treats can invalidate the trial.

Water

Provide fresh water unless a veterinarian gives specific temporary instructions. Increased thirst, reduced drinking, coughing at the bowl or difficulty swallowing can be medical signs. Water additives should follow label directions and not remove access to plain water unless instructions specifically require it.

Chihuahua living conditions

Chihuahuas can thrive in apartments, houses and senior households when their safety and behavioral needs are met. Square footage matters less than temperature, floor traction, bathroom access, secure barriers and daily enrichment.

Apartment life

Teach quiet settling around hallway, elevator and neighbor sounds. Use window film, white noise, distance and reward-based desensitization instead of shouting over barking. Provide regular outdoor opportunities even when an indoor toilet option is available for emergencies.

Temperature

Offer warm bedding away from drafts and use an appropriate coat outdoors in cold weather. In hot climates, walk during cooler hours and maintain air conditioning. Tiny size does not protect from heatstroke, while a blanket does not make severe cold safe.

Floors and furniture

Use nonslip runners, stable ramps and gates. Keep recliner mechanisms, doors and sofa cushions in mind, because a tiny dog can be unseen. Check before sitting, closing a door or moving furniture. Prevent access to balcony and railing gaps.

Travel and carrying

A secure crash-tested restraint is safer than a loose lap. Train the carrier with food and rest before travel. A handbag is not an exercise plan, and an open tote does not protect during a sudden stop. Let the dog walk in safe places to preserve confidence and fitness.

Chihuahua cost of ownership in the United States

Purchase price varies widely, but unusual color and “teacup” marketing do not buy health. Budget beyond the puppy: a small dog uses less food, yet dental, heart, orthopedic, eye and emergency care can be substantial.

Setup and recurring costs

• Veterinary intake examination and record review
• Secure harness, leash, identification, carrier and travel restraint
• Warm bedding, gates, ramps and nonslip runners
• Complete food, parasite prevention and routine care
• Dental supplies and professional dental treatment
• Insurance, emergency fund and qualified pet care

Possible major expenses

Patella surgery, cardiac imaging and medication, corneal emergencies, tracheal evaluation, neurologic diagnostics, fracture treatment and advanced dental work can each become significant. Request local estimates and read insurance hereditary, congenital, bilateral and dental exclusions.

Chihuahua history

The Chihuahua is named for the Mexican state of Chihuahua and is associated with small companion dogs of ancient Mexico. The Techichi, kept by Toltec culture, is often discussed in the breed's ancestry. Modern development involved dogs brought into the United States from Mexico during the nineteenth century.

The American Kennel Club recognized the Chihuahua in 1904. The long and smooth coats are varieties of one breed. History explains cultural importance, but it should not be used to justify extreme miniaturization or poor health.

Chihuahua facts and trivia

• The Chihuahua is the smallest AKC dog breed by standard weight.
• The breed takes its name from the Mexican state of Chihuahua.
• Smooth and long coats are recognized varieties.
• The standard weight is no more than six pounds.
• Many colors and markings occur.
• The AKC standard describes an apple-dome skull.
• Teacup, miniature and deer head are not separate AKC varieties.
• Cross labels such as Chug and Pomchi do not guarantee size, coat or health.

Choosing a Chihuahua puppy or rescue

A responsible breeder prioritizes stable temperament and health over color, novelty, or extreme size. They should let you meet the mother when practical, explain early socialization, provide a contract and veterinary records, discuss lifetime support, and show publicly verifiable health tests for both parents. They will also ask whether your home suits the puppy.

Red flags include multiple breeds always available, pressure to pay quickly, no live conversation, handoff in a parking lot, refusal to show living conditions, or claims that DNA breed panels replace health screening. Search the OFA database yourself using the parents' registered names.

Adult Chihuahuas and mixes also enter breed rescues and shelters. An adult's established size and behavior may make matching easier, and a foster-based rescue can often describe home habits in detail.

Questions to ask a breeder

1. What are the parents' registered names and OFA links?
2. What are their cardiac, patella and ophthalmologist results?
3. What heart, knee, eye, tracheal, dental or neurologic disease occurred in relatives?
4. How old are grandparents and older relatives, and what caused deaths?
5. How are puppies socialized to handling, surfaces, sounds and calm dogs?
6. How does the breeder prevent hypoglycemia and monitor growth?
7. Will the breeder take the dog back at any age?

Red flags

• Price based mainly on projected tiny size or rare color
• A guaranteed adult weight presented as exact
• Only a commercial DNA panel with no cardiac, patella or eye screening
• Parents unavailable for observation or mismatched records
• Puppies leaving before eight weeks or without full veterinary records
• No contract, return commitment or questions about your home
• Pressure to pay immediately or meet in a parking lot

Adopting a Chihuahua

Ask the shelter or foster about handling, teeth, heart, knees, eyes, house training, barking, animals, children and time alone. Request medication, surgical and dental records. A foster home may provide better daily-life evidence than a short kennel assessment.

Keep the first days quiet, continue the current food briefly and allow sleep. Introduce people and animals gradually. Arrange an intake examination, transfer the microchip and identify the nearest emergency hospital.

First-week checklist

• Book an intake examination and dental assessment.
• Record weight, body condition, gum color and resting behavior.
• Check harness fit, railing gaps, floors, furniture and yard security.
• Set up warm bedding and climate control.
• Start a meal, medication and symptom log.
• Focus early training on trust, safety and predictable routines.

Frequently asked questions

How long do Chihuahuas live?

The AKC gives a typical range of about 15–17 years. Genetics, preventive care, body condition, dental health, and individual disease all affect lifespan.

Do Chihuahuas shed?

Yes. Both smooth- and long-coated Chihuahuas shed, although the pattern and amount vary by dog and season. No Chihuahua coat is guaranteed not to trigger allergies.

Are Chihuahuas easy to train?

They are intelligent and can learn quickly. Consistent reward-based training, frequent house-training breaks, and early socialization usually produce better results than punishment.

Can a Chihuahua live in an apartment?

Yes, provided the dog receives daily exercise, mental enrichment, house-training opportunities, and help learning to settle around hallway and neighbor noises.

What is the difference between a deer-head and apple-head Chihuahua?

These informal terms describe appearance. The AKC standard describes a rounded “apple dome” skull; “deer head” is not a separate registered breed or variety.

Is a teacup Chihuahua a separate breed?

No. Teacup is a marketing term for an exceptionally small Chihuahua. It is not an AKC variety, and selecting for extreme size can increase health and injury risk.

How much exercise does a Chihuahua need?

Many healthy adults enjoy around 30 minutes of walking and play divided across the day, adjusted for age, knees, heart, weather and fitness.

Are Chihuahuas good with children?

They can suit calm families with older children who follow safety rules. Their tiny frame makes falls and rough handling dangerous, so active adult supervision is essential.

What health tests should Chihuahua parents have?

The Chihuahua Club of America recommends cardiac, patella and ophthalmologist evaluations. Buyers should verify each result in the OFA database.

What is the best food for a Chihuahua?

Choose a complete and balanced life-stage diet, weigh small portions and adjust calories to body condition. There is no single best formula for every dog.
