Distinctive Features
  • Ancient Mexican breed; companion and watchdog within domestic dog lineage.
  • Two varieties: hairless and coated; not all individuals are fully hairless.
  • Hairless variety often has sparse hair on head, tail tip, and feet.
  • Skin feels warm and smooth; pigment varies and can freckle over time.
  • Wedge-shaped head with large, upright bat-like ears.
  • Almond-shaped eyes; expression alert and reserved with strangers.
  • Hairless gene commonly linked to missing premolars and other dental anomalies.
  • Common skin concerns: acne, comedones, dryness, and irritant dermatitis.

Did You Know?

The name combines the name of an Aztec god with an Indigenous Mexican word meaning "dog".

Xolos come in three sizes: toy, miniature, and standard within one breed.

Both hairless and coated puppies can appear in the same litter.

Hairlessness is tied to the FOXI3 gene and often pairs with missing teeth.

Pre-Columbian ceramics from Colima and other regions depict Xolo-type dogs vividly.

They're known as alert watchdogs that bond closely with one family.

Their nearly bare skin makes body heat easy to feel-part of their "living heater" reputation.

Unique Adaptations

  • Hairless skin improves heat transfer, making them feel unusually warm to the touch.
  • Sparse hair and reduced dander can be easier for some allergy-sensitive owners (not truly hypoallergenic).
  • FOXI3-linked dentition differences mean hairless Xolos may have fewer premolars.
  • Pigmented skin helps protect from sunlight, though sunburn remains a risk.
  • Lean, athletic build supports endurance and agility despite a calm indoor temperament.

Interesting Behaviors

  • Forms intense bonds and often chooses a "favorite person" in the household.
  • Naturally vigilant; tends to silently observe, then gives a decisive alert bark.
  • Enjoys close contact and seeks warm spots, blankets, and sunbaths year-round.
  • Typically clean and low-odor; many groom themselves with cat-like fastidiousness.
  • Can be reserved with strangers but affectionate and playful once trust is earned.

Cultural Significance

In Mesoamerica, Xolo-type dogs were associated with guidance in the afterlife and appear in ancient art and burial contexts. Today they're celebrated as a national breed of Mexico and a symbol of indigenous heritage.

Myths & Legends

In Aztec tradition, a god was said to gift the Xoloitzcuintli to humans to guard homes and guide souls through the Aztec underworld.

Accounts from western Mexico describe dogs placed in tombs so they could help their owners navigate the journey after death.

In Aztec central Mexico, a dog guided the dead across an underworld river to reach the afterlife, a role linked with the god Xolotl.

The Xoloitzcuintli (pronounced “show-low-eats-queen-tlee”), also known as the Mexican hairless or simply the Xolo, is among the most ancient and venerable of all dog breeds worldwide.

The Xoloitzcuintli was first recorded in the American Kennel Club stud book in 1887, but after being dropped from the registry for many years, it regained full AKC recognition in 2011. However, by the time of its revival, the Xolo was already transformed. Genetic analysis has revealed that the Xolo interbred with Eurasian breeds to such an extent that the modern version has only a little of the pre-Columbian lineage intact.

The Origin Of The Breed

Dating back some 3,000 years, the Xolo has a long and fascinating history. It was common practice to sacrifice and bury the dog in its owner’s tomb.

The ancient people of Mexico believed that the Xolo would help guide the soul of its owner on the journey to the underworld. After the rise of the Aztec civilization, the breed was associated with their dog-headed god of death, Xolotl. To produce its current name, Xolotl was combined with the word itzcuintli, meaning dog in the local Nahuatl language.

Following the Spanish conquests, this breed entered a long period of decline, since the conquerors often associated the Xolo with the pagan culture that produced it. After nearly becoming extinct, the Xolo’s prospects improved dramatically in the 20th century thanks to the efforts of determined breeders and a revival of interest in Mexico’s pre-Columbian culture.

Appearance

The modern Xolo is characterized by a sleek body, a wedge-shaped head, large bat-like ears (either erect or floppy), an expressive face, and a wrinkled forehead. Hairlessness is the dominant trait, but some puppies will be born with a recessive trait for a short, flat coat. This recessive haired trait persists because if a dog inherits two hairless copies of the gene, it will die early in development. Therefore, all hairless Xolos that survive to birth actually carry the recessive haired trait. It takes a combination of two recessive genes to produce the haired version. Black, gray, brown, brindle, red, liver, and bronze are the most accepted colors. Spotted patterns are also allowed.

Today, the Xolo is mostly intended as an indoor dog. It makes for an excellent watchdog and companion around the home.

Pros And Cons of Ownership

Pros!Cons!
The Xoloitzcuintli is a loyal and protective friend.This breed needs plenty of social and mental stimulation throughout the day.
The hairless version is a great choice for people with serious allergies.Because of its hairless trait, the Xolo’s skin is sensitive to sunlight, bad weather, and environmental irritants.
The Xolo has very few inheritable conditions and an overall excellent lifespan.The Xolo prefers familiar faces rather than new ones.

Size and Weight

The standard-size Mexican hairless dog weighs between 30 and 55 pounds.

The Xoloitzcuintli comes in two types, hairless and coated, and three different sizes: toy, miniature, and standard. The toy version usually measures between 10 and 15 pounds. The miniature is 15 to 30 pounds. Finally, the standard is 30 to 55 pounds. The smaller dogs tend to have thinner skin, but the skin of all three types can vary in thickness.

Common Health Issues

Since the Xolo was allowed to develop freely with little artificial selection by humans, it has few inheritable health problems that plague other breeds. This also means it has an excellent life span of 13 to 18 years. The breed does suffer from dry skin, some drug sensitivities, cancer, and joint issues. Owners should also look out for kennel cough, meaning an infectious disease that produces a very harsh coughing sound.

Any new puppy should have a thorough medical examination for common developmental disorders of the joints, eyes, and heart. Ideally, this service should be provided by your breeder before the point of purchase. You should also schedule regular appointments at the vet to catch any early signs of health problems. In summation, these are the most common health problems in the Xolo:

  • Dry skin
  • Allergies
  • Cancer
  • Joint issues

Temperament

Xoloitzcuintlis have friendly personalities, but make good watchdogs.

The Xoloitzcuintli has an all-around friendly personality. It’s fairly playful and attentive, affectionate with the family, highly intelligent, and sensitive in nature. This breed does tend to bond very strongly with a single person, but they will accept all members of the family as a friend, including other dogs.

Because of their wariness of strangers and protective nature, they make good watchdogs (though not necessarily good guard dogs). They do need quite a lot of mental stimulation every day in the form of playtime, brain exercises, and other activities. If they do not receive enough attention or activities, they might occupy themselves by engaging in unwanted or destructive behavior.

Care

While some prior dog ownership experience is recommended, the Xoloitzcuintli is a good choice for many different types of owners. This breed can adapt to a wide range of different living situations and daily schedules, and owners won’t need to spend too much time on grooming and care.

Best Dog Food

Remember to take your Xolo’s size and activity level into account for proper food portioning. Additionally, Xolos’ skin needs a little extra TLC. So, look for dog food that helps prevent dry skin and contains ample, natural nutrition to keep cancers and joint issues at bay.

The size of your dog will largely dictate how much food it needs. A toy dog may need as little as half a cup of high-quality dog food per day, while the standard-sized Xoloitzcuintli may need more than 2 cups per day. Highly active and younger dogs will also need more food than inactive dogs.

Maintenance and Grooming

Grooming the Xoloitzcuintli should be a relatively easy task. The coated variety requires minimum brushing, probably no more than once a week. The hairless variety will need to be wiped down with a damp cloth and bathed with a light moisturizer, but bathing too often may strip the natural oils from the skin. Owners should also check their ears regularly for signs of infection and use a cotton swab while cleaning.

The nails should be trimmed about twice a month to prevent them from becoming uncomfortable and annoying to deal with. Tooth brushing nearly every day is also necessary to maintain proper dental hygiene. When venturing outside into the sun, hairless dogs will always need sunscreen (or at least thick clothing) to protect their vulnerable skin.

Training

The Xoloitzcuintli is a highly trainable breed, eager to learn and good at following instructions. But these are sensitive dogs that benefit from positive reinforcement methods and respond very poorly to harsh words and actions. Owners will need to set boundaries early and remain consistent throughout the entire process.

Exercise

The Xoloitzcuintli needs a moderate amount of exercise, around 45 minutes every day. It should be satisfied with long walks around the block, fetching, and vigorous playtime. It might be a good idea to keep the dog on the leash outdoors to prevent it from chasing after smaller animals.

Puppies

This tiny, cute Xoloitzcuintli puppy will need to be introduced to new situations and settings as early as possible.

Xoloitzcuintli puppies are a real handful to care for. They are considered to be bundles of energy even after the point of maturation and probably won’t settle down until around two years old. Fortunately, the adults are actually known for being quite calm and well-behaved. Until that point, they will benefit immensely from an early direction in the form of training and socialization.

You should expect to spend the first several months with your dog teaching it everything from basic household etiquette to more advanced commands. The dog should be introduced to new situations and settings as often and early as possible. Crate training can help with housebreaking and early behavior issues, but it’s not strictly necessary.

Children

The Xoloitzcuintli should get along fairly well with children of all ages. The only caveat is that they may not like rough play if it means their ears and tail are pulled. All interactions between your children and your dog should be supervised by an adult.

Famous

The Xoloitzcuintli is a popular breed in its native Mexico and has begun to receive more attention internationally. The first-ever Xolo recognized in the United States was a dog named Mee Too in 1887. Chinito Junior, owned by Valetska Radtke of New York City, was the first and only Xolo to be recognized as an AKC champion in 1940. More recently, the Xolo was featured in the 2017 Pixar film Coco. It is also the mascot of the soccer team Club Tijuana. Many public figures, including prominent 20th-century Mexican painter Diego Rivera, have owned this breed as well.
