Xoloitzcuintli: breed guide

The Xoloitzcuintli (pronounced "show-low-eats-QUEENT-lee", and usually shortened to "Xolo") is one of the oldest dog breeds in the world, with roots going back roughly 3,000 years in Mexico. It's a genuinely unusual dog to bring into a UK home: still rare here, still striking to look at, and still surrounded by more myth than most breeds. If you're considering one, it helps to separate the folklore from the practical reality of living with one.

The headline feature is the coat, or lack of it. Xolos come in a hairless variety and a coated variety, and both can appear in the same litter, since they share identical body type and temperament — they differ only in coat and, in the hairless dog's case, in dentition. They also come in three sizes, so a Xolo can be anything from a small companion dog to a substantial, athletic animal, which makes "what's a Xolo like to own" a genuinely varied question depending on which one you're looking at.

This guide covers temperament, the three sizes, hairless-specific skin care, dental quirks that are unique to the breed, exercise and training needs, general health, and who this dog realistically suits, so you can make an informed decision rather than one based on how the dog looks in a photo.

What is a Xoloitzcuintli?

The Xoloitzcuintli is Mexico's native dog breed, sometimes called the Mexican hairless dog. According to the American Kennel Club, it is described as "the ancient Aztec dog of the gods" and is recognised in three sizes — toy, miniature and standard — and in two coat types, hairless and coated. The UK Kennel Club recognises the same breed (spelled Xoloitzcuintle in its standard) but currently only on the Import Register, meaning it doesn't yet compete in its own breed class at UK shows and the standard is classed as interim. In practice this also means Xolos are genuinely rare in the UK: you are very unlikely to see one at your local park, and you should expect a long wait and a lot of legwork to find a reputable breeder if you want one.

According to the Kennel Club's breed standard, both hairless and coated Xolos are "natural, primitive type, slim and elegant, moderate in all respects," with a body that's slightly longer than it is tall. This is not a dog that has been shaped by decades of exaggerated show breeding — its proportions are close to what a working, all-purpose village dog would have looked like for millennia, and that's part of the appeal for people drawn to more "natural" breeds.

Sizes: toy, miniature and standard

Unlike most breeds, the Xolo comes in three distinct sizes, all sharing the same standard other than height:

• Toy — the smallest variety, a genuine companion-sized dog.
• Miniature — per the Kennel Club standard, 25–35cm (10–13¾in) at the withers.
• Standard — per the Kennel Club standard, 46–60cm (18–23.5in) at the withers, a properly athletic, medium-to-large dog.

This matters enormously when you're choosing a Xolo, because a toy and a standard are very different propositions in terms of exercise space, handling strength, and how they fit into a household with small children or other pets. Always ask a breeder which size range a puppy is expected to fall into, and meet the parents where possible, since size is one of the few things about a Xolo that isn't identical across the variety.

Temperament

The Kennel Club standard describes the Xolo's characteristics as "cheerful, alert and intelligent," and temperament is consistent across both coat types and all three sizes. Xolos are watchful and can be aloof or wary with strangers, which is a genuine breed trait rather than poor socialisation — but the standard is explicit that they should never be aggressive or timid. This combination — reserved with people they don't know, deeply loyal to their own household — is why the breed has traditionally doubled as both companion and watchdog.

This wariness means early, consistent, positive socialisation is important, more so than with a breed that's naturally outgoing with everyone. A Xolo that meets a wide variety of people, dogs, and everyday situations as a puppy is far more likely to grow into the calm, confident adult the standard describes, rather than one that's simply anxious around anything new.

Cheerful, alert and intelligent, but naturally aloof with strangers — never timid, never aggressive. That's the standard the breed is bred to.

Exercise and mental stimulation

Xolos are working-type dogs underneath the unusual look, and they need a genuine outlet for both body and brain. Daily walks are essential, and because the breed is intelligent and can be strong-willed, purely physical exercise isn't always enough — mental stimulation through training, scent work, or puzzle feeding helps prevent the boredom-driven habits (chewing, digging, excessive vocalising) that intelligent, under-stimulated dogs of any breed tend to develop.

If you're weighing up how much daily activity fits your routine before committing to any dog, our Dog Walking Calculator can help you work out realistic daily walk times for your lifestyle, and it's worth doing that exercise honestly before you bring home a breed this active.

Training

Because the Xolo is genuinely intelligent, training tends to go one of two ways: either it's straightforward because the dog picks things up quickly, or it stalls because the dog gets bored of repetition and decides your commands are optional. Short, varied, reward-based training sessions tend to work far better than long drilling. Given the breed's natural reserve with unfamiliar people, training and socialisation should run side by side from puppyhood — a Xolo that has learned confident, calm responses to new situations early on is a much easier dog to live with as an adult.

Skin care for the hairless variety

This is the section that makes the hairless Xolo genuinely different to almost any other dog you might own, and it deserves proper attention rather than an afterthought.

Hairless dogs lack the coat that protects most breeds from the sun, from cold, and from everyday knocks and scrapes, so their skin needs active management. The American Kennel Club's guidance on skincare for hairless and low-hair breeds is directly relevant here: these dogs face elevated risks of skin cancer, sunburn, and insect bites because they have no fur barrier. Practical steps include:

• Weekly bathing with a shampoo formulated for dogs — the AKC notes that proper rinsing should take longer than the shampooing itself, since leftover product residue is a common cause of dryness and flaking.
• Moisturising after every bath. Shampooing strips natural oils from bare skin, so follow up with a dog-safe lotion or oil (vitamin E, vitamin B, or oils such as baobab are commonly used) to keep skin supple.
• Sun protection. On bright days, a dog-safe sunscreen with an SPF of at least 30, water-resistant and unscented, is genuinely worth using on exposed skin, in the same way you'd protect a fair-skinned person.
• Watching for acne and dermatitis. Hairless skin is more prone to blocked pores and localised infections than a coated dog's, so a mild antibacterial shampoo is often recommended, and any persistent bumps, redness or scabbing are worth a vet check rather than waiting it out.
• Temperature regulation. Without a coat, hairless Xolos feel the cold far more than other dogs and often need a jumper or coat on chilly UK walks, and shade or cooling in hot weather, since they can also overheat or sunburn quickly.

If you're taking on the coated variety instead, most of this doesn't apply — coated Xolos have a normal short, flat coat with no undercoat and need only routine grooming, much like any other short-haired breed.

Dental care and a genuine breed quirk

One of the more surprising facts about hairless Xolos is that missing teeth are a normal feature of the breed, not a health problem. The hairless trait and the dental differences both trace back to the same underlying genetics. Peer-reviewed research published in PLOS ONE on the dental phenotype of hairless dog breeds (which include the Mexican hairless, the Peruvian hairless, and the Chinese Crested) found that hairless dogs are consistently missing their permanent canines, premolars, and to some extent incisors, and that their remaining molars often show a simplified, single-cusp shape rather than the multi-cusped pattern seen in coated dogs. This is a well-documented, breed-typical feature of ectodermal dysplasia linked to the same gene pathway that causes hairlessness — the research treats it as a natural developmental variation rather than a disease.

In practical terms: don't panic if your hairless Xolo's mouth looks different to other dogs' or has fewer teeth than you'd expect. It's still worth having a vet check your individual dog's mouth so they can confirm what's normal for them and rule out anything else. And whatever teeth your Xolo does have still need proper care — dental disease is one of the most common health problems in dogs generally. According to VCA Animal Hospitals, over 80% of dogs aged three and older have some active dental disease, and daily tooth brushing with a dog-specific toothpaste is the single most effective way to prevent tartar build-up, alongside dental chews and diets carrying the Veterinary Oral Health Council seal where appropriate. Watch for pawing at the mouth, bad breath, dropping food, or reluctance to chew, and get any of these checked promptly.

General health

Beyond the skin and dental quirks that are specific to the hairless variety, Xolos are generally considered a robust, naturally-built breed without the extreme exaggerations that cause problems in some more heavily "improved" breeds. As with most medium-to-large, active dogs, joint health (hips, elbows, patellas) is worth keeping an eye on throughout life, particularly in the standard size, and regular vet check-ups are the best way to catch anything early. Because the breed is still uncommon in the UK, it's worth asking any breeder directly what health testing they carry out on their breeding stock, and being wary of anyone who can't answer that clearly.

When to see your vet

Book a vet visit if you notice any of the following in your Xolo:

• Persistent redness, scabbing, lumps or sores on hairless skin that don't resolve within a few days
• Signs of dental discomfort — pawing at the mouth, dropping food, bad breath, or reluctance to chew
• Lethargy, stiffness or reluctance to exercise, which can signal joint problems
• Any sudden change in appetite, energy, or behaviour

Hairless dogs in particular benefit from a vet who's comfortable examining bare skin thoroughly, so don't hesitate to mention any changes, however minor they seem.

Is a Xoloitzcuintli right for you?

Dogs Trust's general guidance on choosing the right dog is a useful lens to apply here: think honestly about your exercise capacity, your living space, your household, and the breed's known temperament, rather than choosing on looks alone. Applied to the Xolo specifically:

• You'll suit this breed if you want an intelligent, loyal, watchful companion and are happy to put in the socialisation work to keep that natural wariness from tipping into anxiety.
• The hairless variety suits owners prepared to actively manage skin care — bathing, moisturising, sun protection and cold-weather coats — as a routine part of ownership, not an occasional chore.
• Because Xolos are still rare in the UK, be prepared for a longer search for a reputable breeder, and ask plenty of questions about health testing and the size range you can expect from a litter.
• They are not the easiest first dog for someone wanting a breed that's instantly friendly with every stranger it meets — that's simply not the breed's natural temperament.

If you're weighing up a Xolo against other options, our Pet Ownership Quiz can help you think through lifestyle fit before you commit to a breed this distinctive.
