23 Dog Breeds That Start With M, From Ancient Companions to Modern Mixes
October 25, 2026
Few letters of the alphabet cover as much canine ground as M.

For readers building a complete alphabetical picture of the dog world, this guide pairs well with our list of dog breeds that start with L, which covers several other companion and working breeds.
1. Maltese
The Maltese is one of the oldest toy breeds in the Western world, with roots tracing back to the ancient Mediterranean island civilizations that gave the breed its name. Bred almost exclusively as a companion for centuries, the Maltese carries no working-dog job description in its history, just a long resume as a lap dog for nobility and merchants alike.
Physically, the breed is instantly recognizable by its long, silky, pure-white coat that lacks an undercoat, which is why Maltese dogs shed very little compared to double-coated breeds. They typically weigh under seven pounds, fitting comfortably into apartment life, though their coat requires daily attention to prevent matting and tear staining around the eyes.
Pro Tip: Wipe a Maltese’s face daily with a damp cloth to reduce tear staining, and schedule brushing sessions every day rather than weekly to keep the long coat tangle-free.

2. Mastiff
At the opposite end of the size spectrum sits the Mastiff, a giant English breed descended from ancient war dogs and estate guardians. Males can weigh well over 150 pounds, with a broad skull, deep chest, and loose jowls that give the breed its unmistakable silhouette.
Despite the intimidating size, Mastiffs are generally calm, affectionate, and protective without being aggressive by nature. They form strong bonds with their families but need early socialization to manage their sheer physical presence around visitors and children.
Key Insight: A Mastiff’s size comes with real space and budget demands, from larger food portions to furniture-sized dog beds, so prospective owners should plan for those costs before adopting.

3. Manchester Terrier
The Manchester Terrier originated in 19th-century England, developed in the city of Manchester specifically for rat-catching contests and small-game hunting. The breed comes in two size varieties, Standard and Toy, both sharing the same sleek black-and-tan coat and wedge-shaped head.
True to its terrier roots, the Manchester Terrier is alert, energetic, and quick to chase small moving objects, a trait that traces directly back to its vermin-hunting job description. The breed’s smooth, short coat makes grooming simple, requiring only occasional brushing to keep the shine.

4. Miniature Schnauzer
Bred down in size from the Standard Schnauzer in Germany, the Miniature Schnauzer was originally developed as a farm ratter before becoming one of the most popular small breeds in the United States. Its wiry double coat, bushy eyebrows, and signature beard give it one of the most recognizable faces in the toy and small-breed world.
The breed is intelligent, alert, and generally low-shedding, making it a common choice for households managing allergies. Miniature Schnauzers do best with regular grooming appointments to maintain the coat’s texture and shape, since the wiry hair grows continuously rather than shedding on a seasonal cycle.
Owners who like the low-shedding, wiry-coated look can find similar traits among the breeds listed under dog breeds that start with K.
5. Miniature Pinscher
Often nicknamed the “King of Toys,” the Miniature Pinscher is a German breed that predates the Doberman Pinscher despite the visual resemblance many people assume runs in the other direction. The breed’s origins actually connect to smaller German pinscher-type ratting dogs crossed with dachshunds and Italian greyhounds.
Min Pins are known for a distinctive high-stepping “hackney gait,” along with a bold, fearless personality that seems to ignore their small stature entirely. Their short, smooth coat needs minimal grooming, but their high energy and independent streak call for consistent training from an early age.

6. Miniature American Shepherd
The Miniature American Shepherd developed in the United States from smaller-statured Australian Shepherds, eventually earning full American Kennel Club recognition as its own breed in 2015. Despite the name, the breed has no direct ties to Australia; the “Aussie” name history is more about the sheep the dogs herded than the country of origin.
This breed carries the same herding drive, intelligence, and merle coat patterns as its larger Australian Shepherd relatives, just scaled down to a more apartment-friendly size. They need consistent mental stimulation and exercise, since herding instincts don’t disappear just because the dog is smaller.
Households drawn to herding-breed intelligence can find more working dogs among dog breeds that start with C, several of which share similar drive and trainability.
7. Miniature Bull Terrier
The Miniature Bull Terrier is essentially a scaled-down version of the Standard Bull Terrier, sharing the same distinctive egg-shaped head profile and muscular, compact build. English breeders developed the smaller variety to keep the same personality and looks in a more manageable package for smaller households.
Playful, mischievous, and stubborn in equal measure, this breed thrives on interaction and can become destructive when bored or left alone for long stretches. The short coat sheds moderately but requires little more than weekly brushing to stay in good condition.

8. Mudi
The Mudi is a Hungarian herding breed that remained largely unknown outside its home country for most of its history. The Hungarian Mudi dog is a herding breed that’s relatively rare outside of their native land, but given the dogs’ athleticism and drive, coupled with American Kennel Club recognition in 2022, interest in the breed is growing. The breed is closely tied to two other Hungarian herders; the Mudi is a herding dog breed from Hungary that is closely related to the Puli and Pumi, from which it was separated in the 1930s.
The Mudi reaches 15 to 18.5 inches tall and 18 to 29 pounds, with a coat that comes in colors including black, white, gray, brown, yellow, and merle. The breed very nearly disappeared from history altogether, since Mudis nearly disappeared soon after their recognition because many were killed during World War II.
Today’s Mudi is known for a busy, alert personality well suited to active households. According to the PetMD breed profile, the dog’s athleticism and working drive make it a strong fit for agility and other dog sports, and the American Kennel Club describes it as a loyal, versatile farm dog that protects property without excessive aggression.
9. Mal Shi
The Mal Shi crosses two beloved toy breeds, the Maltese and the Shih Tzu, to produce a small, affectionate companion dog popular with first-time small-breed owners. This hybrid generally weighs between six and twelve pounds and inherits a soft, low-shedding coat from both parent breeds.
Temperament tends toward friendly and people-oriented, since both parent breeds were developed specifically as companions rather than working dogs. Coat color and texture can vary significantly between individual puppies, ranging from wavy to nearly straight depending on which parent’s genes dominate.

10. Münsterländer
The Münsterländer is a German hunting breed that actually exists in two distinct varieties: the Large Münsterländer and the smaller, spaniel-like Small Münsterländer. Both were developed as versatile gun dogs capable of pointing, flushing, and retrieving across varied terrain.
The breed’s coat is typically white with brown or black patches and ticking, giving it strong camouflage in field settings. Münsterländers are energetic, biddable, and best suited to active families who can provide regular fieldwork or vigorous daily exercise.

11. Mucuchies
The Mucuchíes holds a unique place in South American history as Venezuela’s only native dog breed. Developed in the high-altitude Andes, the breed takes its name from the mountain town of Mucuchíes in Venezuela’s Mérida state, and it was officially named the national dog breed of Venezuela in 1964.
Mucuchíes are thought to descend from large livestock guard breeds such as the Spanish Mastiff, Great Pyrenees, and Pyrenean Mastiff brought over by Spanish colonists, later adapting to the thin air and freezing conditions of the páramo ecosystem. Fully grown, the breed stands 22 to 28 inches tall and weighs between 66 and 110 pounds, giving it the bulk needed to guard cattle from mountain predators.
Important Note: Sources differ slightly on the Mucuchíes’ exact ancestral breeds, with some accounts naming the Algerian Mastiff instead of the Spanish Mastiff, since detailed breeding records from the era were never formally kept.
The breed’s most famous member was Nevado, a Mucuchíes that accompanied Venezuelan independence leader Simón Bolívar. According to Rover’s breed profile, the dog is remembered in statues and paintings around the town of Mucuchíes to this day. Despite that legacy, the breed struggled through much of the 20th century, and Wag! notes that by the 1960s the breed was nearly extinct before conservation efforts began.
12. Morkshire Terrier
Also known informally as the Morkie, the Morkshire Terrier blends the Yorkshire Terrier with the Maltese to create a small, silky-coated companion dog. Most adults weigh between four and eight pounds, making them well suited to apartment living and travel.
The breed typically inherits a mix of the Yorkie’s spunk and the Maltese’s gentle affection, resulting in a dog that’s both playful and cuddly. Coat colors vary widely, from the Yorkie’s traditional tan-and-black to solid white inherited from the Maltese side.
13. Markiesje
The Markiesje, sometimes called the Dutch Tulip Hound, is a small companion breed developed in the Netherlands and recognized relatively recently by European kennel authorities compared to older continental breeds. The name translates loosely to “little marquess,” reflecting the breed’s elegant, refined appearance.
Physically, the Markiesje resembles a small spaniel, with a wavy or slightly curled coat in white with colored patches. The breed remains rare outside the Netherlands and Belgium, and finding a breeder elsewhere in the world can be genuinely difficult.
14. Maltipoo
The Maltipoo, a cross between the Maltese and the Poodle, ranks among the most popular designer dog breeds in the United States thanks to its low-shedding coat and affectionate personality. Depending on whether a Toy or Miniature Poodle was used in the cross, adult Maltipoos can range from roughly five to twenty pounds.
The breed tends to be playful, people-focused, and eager to please, drawing on the best temperament traits of both parent breeds. Coat texture varies from loosely curled to wavy, and while many Maltipoos shed very little, no coat type can be guaranteed completely hypoallergenic.
Common Mistake: Assuming any Poodle mix is guaranteed allergy-friendly. Coat type and shedding levels vary by individual dog, so anyone with allergies should spend time with the specific puppy before committing.
15. Mini Goldendoodle
The Mini Goldendoodle combines a Golden Retriever with a Miniature or Small Standard Poodle, producing a smaller version of the standard Goldendoodle that has become a fixture in family-dog searches across the country. Adults typically weigh between fifteen and thirty-five pounds, depending on the specific Poodle parent’s size.
This hybrid generally inherits the Golden Retriever’s friendly, easygoing nature along with the Poodle’s lower-shedding coat, making it a popular choice for families who want retriever temperament without as much loose hair around the house. Regular grooming is still necessary to prevent the wavy-to-curly coat from matting.
16. Malshi
Spelled as one word or two, the Malshi is the same Maltese-Shih Tzu cross covered earlier in this list, though the name variation shows up frequently enough in searches and breeder listings to warrant its own mention. Multi-generation Malshi litters, sometimes labeled F1B or F2, can show more variation in coat and size than first-generation crosses.
Because both parent breeds were bred purely for companionship, Malshi puppies typically adapt well to apartment living and enjoy being close to their people throughout the day. Early socialization helps manage the small-dog tendency toward wariness of strangers or loud environments.
17. Malchi
The Malchi pairs the Maltese with the Chihuahua, resulting in a tiny hybrid that often weighs under ten pounds fully grown. This cross tends to inherit the Chihuahua’s alertness and watchdog instincts alongside the Maltese’s softer, more affectionate side.
Coat length and texture depend heavily on which Chihuahua variety, smooth or long-haired, appears in the cross. Malchis generally do well in smaller living spaces but benefit from early exposure to a variety of people and situations to prevent excessive shyness or yappiness.
18. Mastador
The Mastador crosses the giant Mastiff with the family-friendly Labrador Retriever, producing a large, loyal companion that softens some of the Mastiff’s sheer bulk with the Labrador’s more moderate build. Even so, Mastadors commonly grow to well over 100 pounds and need substantial space to move around comfortably.
Temperament tends toward gentle and protective, drawing on the guardian instincts of the Mastiff and the sociable nature of the Labrador. Early training matters given the breed’s size, since even friendly pulling on a leash can be difficult to manage without practice.
19. Mudhol Hound
The Mudhol Hound, also known as the Caravan Hound, is a sighthound breed native to the Karnataka region of southern India, historically used by nomadic and hunting communities to chase game across open terrain. The breed has a lean, athletic build built for speed and endurance rather than raw power.
Coats can be smooth or feathered, typically in solid colors or with minimal markings, and the breed’s deep chest and narrow waist reflect its sighthound heritage. The Mudhol Hound remains rare outside India, though interest has grown as international breeders take note of its athleticism.
20. Malinois X
“Malinois X” refers broadly to any crossbreed involving the Belgian Malinois, a working breed already known on its own for intense drive, high energy, and use in police and military roles. Crossing a Malinois with another breed typically tempers some of that working intensity while retaining much of the intelligence.
These crosses vary enormously depending on the second parent breed, but most retain a strong need for structured exercise, mental work, and an experienced handler. Malinois crosses are generally not recommended for first-time dog owners due to their exercise and training demands.
21. Mally Foxhound
The Mally Foxhound is a less common cross between the Belgian Malinois and the American Foxhound, combining a herding breed’s sharp focus with a scent hound’s stamina and independence. This mix tends to be athletic, high-energy, and happiest with a job or serious daily exercise routine.
Because both parent breeds were developed for demanding working roles, the Mally Foxhound typically doesn’t do well as a low-activity apartment pet. Owners considering this mix should plan for significant daily exercise, ideally including off-leash activities like running or hiking in secure areas.
22. Malteagle
The Malteagle brings together the toy-sized Maltese and the scent-driven Beagle, an unusual pairing that produces a small dog with a surprisingly strong nose for its size. Weight typically falls between ten and twenty pounds, larger than a purebred Maltese but still compact.
This hybrid often inherits the Beagle’s curiosity and food motivation alongside the Maltese’s affectionate, people-focused temperament. Because of the Beagle influence, Malteagles may be more vocal and scent-driven than other Maltese mixes, so secure fencing and recall training matter more here than with purely toy-breed crosses.
23. Maltipom
Rounding out this list, the Maltipom combines the Maltese with the Pomeranian, producing a fluffy, feisty toy hybrid that typically weighs between five and ten pounds. The cross often inherits the Pomeranian’s fox-like face and thick coat alongside the Maltese’s gentler disposition.
Maltipoms tend to be affectionate with their families but can be wary of strangers without early socialization, a trait inherited more from the Pomeranian side. Their coat requires regular brushing to prevent matting, particularly around the ears and hindquarters where the fur tends to grow thickest.
From the ancient Maltese to newer hybrids like the Maltipom, dog breeds that start with M cover an unusually wide range of sizes, jobs, and temperaments. Before settling on any breed or mix from this list, it helps to weigh a few practical factors:
- Match the breed’s exercise and space needs to your actual living situation, not just its size on paper.
- Budget for grooming, whether that means daily brushing for a Maltese-type coat or professional trims for a wiry Schnauzer coat.
- Ask about health screening for breed-specific issues, especially with giant breeds like the Mastiff or Mucuchíes.
- Work with a reputable breeder or rescue, particularly for rarer breeds like the Mudi, Markiesje, or Mudhol Hound where fewer options exist.
