Distinctive Features
  • Very small companion-dog frame, smaller than typical domestic dogs.
  • Coat varies: hairless with crest, or longer-coated "powderpuff" style.
  • Large upright ears common, sometimes semi-erect depending on mix.
  • Prominent rounded eyes and short muzzle, Chihuahua influence.
  • Fine-boned legs with delicate feet; "deer-head" or "apple-head" variability.
  • Hairless individuals may have soft, warm skin with visible spotting.
  • Feathering on head, tail, and feet often retained even when hairless.
  • Compared with base species, reduced muzzle length and overall size.

Sexual Dimorphism

Sexual dimorphism is mild: males are usually slightly larger with broader head and chest. Females often appear finer-boned and lighter, though coat type and body shape vary widely due to mixed ancestry.

  • Slightly broader skull and stronger jawline appearance.
  • Heavier chest and thicker neck relative to body size.
  • Finer bone structure with narrower chest and lighter frame.
  • Often slightly smaller overall, especially in shoulder height.

Did You Know?

Chi-Chi isn't a standardized breed; littermates can look very different in coat, size, and ear shape.

Some inherit the Chinese Crested hairless gene (FOXI3), so they may need sunscreen and sweaters.

Many keep the Chihuahua "apple head" and big eyes, but may have the Crested's finer bone structure.

Their toy size often means less stamina and higher cold sensitivity than many larger dogs.

Dental crowding is common in both parent lines, so daily tooth brushing matters more than in many breeds.

Their alert "watchdog" streak often comes from Chihuahua ancestry, despite being bred mainly for companionship.

Unique Adaptations

  • Hairless/crested coat options reduce shedding but increase skin-care needs and vulnerability to sunburn.
  • Large ears and watchful eyes support strong environmental awareness, useful for a small companion's "early warning" style.
  • Compact body and low exercise requirements fit well in apartments, unlike many larger domestic dog types.
  • Toy-breed metabolism can be fast; small, frequent meals may help prevent low blood sugar in tiny individuals.
  • Mixed-breed genetics can lower or raise risk unpredictably, so health screening is more informative than appearance.

Interesting Behaviors

  • "Velcro dog" tendencies-shadowing a favorite person and seeking warmth under blankets or on laps.
  • Quick alarm barking at new sounds, paired with rapid settling when properly socialized and rewarded.
  • Sun-bathing or heat-seeking behavior, especially in hairless or thin-coated individuals.
  • Fast learning with soft methods; harsh correction can trigger fear, shutdown, or defensive snapping.
  • Face-rubbing and rolling after baths or lotion, a common response when skin feels dry or itchy.

Cultural Significance

Chi-Chi reflects modern "designer mix" culture: small, people-focused companion dogs suited to urban living. It also echoes long histories of toy dogs in households across China and Mesoamerica.

Myths & Legends

In Aztec belief, the god Xolotl's dog guided souls through the underworld; dogs were sometimes buried to help the dead cross safely.

Toltec and later Aztec traditions described small companion dogs (often linked to the Techichi) as guides for the deceased on their journey.

Chinese eclipse lore tells of Tiangou, a heavenly dog that devours the sun or moon, prompting people to make noise to drive it away.

The Chinese zodiac "Great Race" story says Dog arrived late after stopping to bathe, explaining Dog's loyal, playful nature in folklore.

Quick Take

  • Sustaining the spunk of this active breed requires limiting total consumption to 1 cup of food daily.
  • The luxating patella condition in toy breeds creates a high risk of knee joint displacement.
  • It is ironic that hairless varieties actually require more topical skincare than their long-haired counterparts.
  • Conducting genetic health testing during the scouting process is necessary to avoid expensive veterinary bills.

The Chi Chi is a mixed-breed dog created by combining the genetics of a Chinese Crested dog and a Chihuahua. These hybrid dogs are sometimes called “designer dogs” to differentiate them from mutts or unknown mixed-heritage pups. Depending on the features of their parents, Chi Chi’s can be fluffy, hairless, or everything in between and make for excellent cuddle buddies. These tiny dogs can be noisy, thanks to their Chihuahua heritage, which makes them excellent watchdogs. 

Tiny and exceptionally adorable, the Chi Chi is a fun-loving and mischievous dog that doesn’t need much to be happy. Suppose you’re looking for a perfect family dog for a smaller house or apartment living, or simply want an affectionate and relatively low-maintenance companion. In that case, the Chi Chi may be the perfect pet for you.

History of the Breed

The Chi Chi is considered a designer breed that is a cross of the Chihuahua and the Chinese Crested.

The Chi Chi is a relatively new breed of dog that seems to be more popular in Asia and Europe than in the United States, and not much is known about where they were created or when. They are considered a designer breed that is a cross of the Chihuahua and the Chinese Crested. They go by a few other names, like the Mexican crested and the crested Chi. Its parent breeds have a longer history.

The Chihuahua is the smallest recognized breed and is named for the Mexican state of Chihuahua, where it was thought to have originated in the 1800s. It is said that they came from a little dog known as the Techichi that was kept by the Toltec people of Mexico, which was thought to have been bred with the Mexican hairless dog known as the Xoloitzcuintli.

The Chinese crested’s exact origins are not quite known, although it is thought that they originated in the 16th century, with origins in China and Africa. It is thought that in ancient times, large hairless dogs were brought to China from Africa, which were then bred down to their reduced size, giving us the dogs of today.

The Best Dog Food For Chi Chi

Chi Chis are highly energetic, with a surprising amount of spunk in their small size. Because they’re so tiny, they don’t need more than a cup of kibble daily to satisfy their food and energy requirements.  

You should opt to provide your pup food comprised of high-quality ingredients and real-food components such as veggies like sweet potatoes and real meat with high protein content. Chi Chi mouths can’t chew larger kibble chunks; better to give them tiny-breed food to provide optimal digestion and absorption. Both kibble and wet food work well, so long as the food is specifically designed for small dogs. 

3 Pros and Cons of Owning a Chi Chi

ProsCons
Hypoallergenic
While fur comes in different lengths and colors, Chi Chis are usually hypoallergenic dogs.
They Have Tons of Energy
These high-energy dogs need activity and can sometimes be tricky to manage if your lifestyle can’t keep up with them.
They’re Excellent Watch Dogs
Chi Chis will immediately inform you if someone is on your property. 
Yappy
While they’re excellent watchdogs, sometimes the barking can get out of control without proper training.
They Love Being in a Pack
The breed loves hanging out with other dogs in the family and is a perfect addition if you already have pets.
Think they are the boss
Without proper training, these pups can think they’re the head of the household and won’t pay heed to commands.

Size and Weight

The Chi Chi female’s average height ranges between 5 and 12 inches, with males averaging around the same size.

The size and weight of any individual dog depend upon its parents’ characteristics. The Chi Chi female’s average height ranges between 5 and 12 inches, with males averaging around the same size. Males can weigh up to 12 pounds when fully grown, and females hover between 7 and 10 pounds.

Common Health Issues

Many toy dog breeds can develop a condition called luxating patellas, in which one or both knees can slip out of the joint socket.

Chi Chis have the potential to develop similar health conditions found in both Chihuahuas and Chinese Crested dogs, and the risk increases if you purchase your hybrid pooch from an irresponsible breeder. 

Many toy dog breeds can develop a condition called luxating patellas, in which one or both knees can slip out of the joint socket. Depending on the severity of the condition, luxating patellas can be a relatively minor issue or require surgical intervention to correct them. Small dogs like this breed can also develop eye diseases such as glaucoma, retinal atrophy, dry eye, and lens luxation.

Before adopting or purchasing a dog, be sure to research the breeder or the mutt’s parents as much as possible. If buying from a breeder, ask for health testing to ensure the puppies won’t carry genetic diseases. This could potentially save you big bucks at the veterinarian down the line.

Temperament

This hybrid breed is usually affectionate, friendly, and intensely devoted to its loved ones. Some may inherit the suspicious nature of their Chihuahua parents, but owners can usually train this out with early socialization.

These pups are intelligent and fun-loving, easy to take care of with little maintenance. They don’t mind staying at home while their family’s at work or school, but they thrive on the daily love they receive when the family returns. These dogs can get along well with children, especially older kids who know how to treat small dogs gently, and they often enjoy the outdoors with human and animal friends.

Chi Chis can be noisy, which can either be a nuisance or make them an excellent watchdog, ready to alert you to any intruder. Their small size and smarts make them a fun companion to adventure with, easily tucked in a bag or carried from place to place, and ready to put a smile on people’s faces.

How To Take Care of Chi Chi 

Depending on their parents, Chi Chis can have short hair, long hair, or be entirely hairless.

New owners wondering how to care for their new pup must consider a range of unique lifestyle factors to provide their dog with the best possible environment and life. Awareness of proper grooming maintenance, exercise, and training needs for this social, intelligent breed will keep your dog healthy and happy for the rest of their lives.

Maintenance And Grooming

Depending on their parents, Chi Chis can have short hair, long hair, or be entirely hairless. Dogs without hair require hardly any daily grooming, but they benefit from regular baths to eradicate dirt and debris from irritating their skin. Hairless varieties should also wear sunblock to prevent sunburn and require regular moisturizing to keep their skin healthy.

Chi Chis with hair benefit from a brushing every few days to keep their coat in top shape, free from mats or tangles. Both hairless and haired dogs regularly need their nails trimmed, at least once a month or as necessary. Keeping their ears clean and dry will prevent ear infections, and daily tooth brushing goes a long way to mitigate gum disease or dental issues. Small dogs are especially prone to teeth concerns, and an ounce of prevention is worth more than a pound of treatment.

Training

Chi Chis should start their training routine as soon as they’re brought home to quickly acclimate them to their new family and allow them to be effectively managed by members of the household. Obedience training provides structure to your new pup, preventing them from thinking they’re the boss. These dogs are brilliant, so they can quickly learn commands like sit, stay, and come, even when they’re young.

Exercise

Chi Chis contain a surprising amount of energy for such small dogs, but their activity levels are easily adaptable to suit their owners’ lifestyles. A 30 to 45-minute walk or regular playtime each day will satisfy them, though some dogs love to fetch or play a game of chase in a backyard or park. These dogs love being the center of attention and do well in various dog competitions, such as obedience sports and agility courses. Regular training also stimulates their mental faculties and counts as its own form of exercise for these pups.

Puppies

Don’t leave Chi Chi puppies outdoors alone, even in a fenced yard, as these pups are easy targets for predator animals such as hawks or coyotes.

Chi Chi puppies are incredibly adorable and are recognized as a designer hybrid breed, though they are less common than some other hybrids. Unfortunately, this makes the breed a susceptible target for greedy puppy mill breeders. However, dogs can often be found up for adoption, so it’s worth looking into local adoption organizations or shelters. 

Once adopted, puppies require commitment and attention to introduce them to the rules of your household. Don’t leave them outdoors alone, even in a fenced yard, as these pups are easy targets for predator animals such as hawks or coyotes. With regular training and supervision, your dog will grow into a happy and well-functioning family member. 

Chi Chi And Children

While Chi Chis get along with children of all ages, they may be better suited for houses with older kids who know how to treat a dog gently. Toddlers can be clumsy and may accidentally hurt the dog without proper guidance or supervision. The breed needs socialization and early-age training to learn how to interact with humans, but with care and work, these dogs fit comfortably into your family’s and children’s lifestyle.

Dogs Similar to Chi Chi

The Chi Chi is closely related to its two parent breeds, the Chihuahua and the Chinese Crested dog, but its diminutive stature shares similarities with the Papillon.

  • Chihuahua: These dogs may be little, but they are fierce, as well as fiercely loyal to their families.  
  • Chinese Crested: These hairless canines are more similar to their descendant, but they’re both avid barkers.
  • Papillon: The Papillon shares in the Chi Chi’s small size and friendliness with humans and other dogs.
