Smallest dog breeds have captured the hearts of pet lovers around the world for centuries, and it is easy to understand why. These compact, portable, and often surprisingly bold little dogs pack enormous personality into bodies that sometimes weigh less than a bag of sugar. Whether you live in a city apartment, prefer a dog you can comfortably carry, or simply find tiny breeds irresistible, understanding the genuine smallest dog breeds on the planet helps you make a genuinely informed choice about which one suits your lifestyle best.
All height and weight data referenced in this guide are sourced from the American Kennel Club official breed standards, which represent the most widely recognized benchmark for breed size classification in the United States.
Before getting into the individual breeds, it helps to understand what makes a dog breed officially small. The American Kennel Club organizes the smallest companion breeds under its Toy Group classification, which groups breeds primarily by their function as companion animals rather than by working ability. However, many of the tiniest breeds in the world carry working heritage from their past, including ratting, watchdog duties, and even circus performance, which explains the bold, alert, and sometimes surprisingly feisty temperaments you find in many small dog breeds today.

1. Chihuahua
Height: 5 to 8 inches (12 to 20 cm)
Weight: 2 to 6 pounds (0.9 to 2.7 kg)
The Chihuahua holds the official title of the smallest dog breed in the world by breed standard, and it is one of the most recognizable dogs on the planet. Named after the Mexican state of Chihuahua, this breed has ancient roots that trace back to pre-Columbian civilizations in Mesoamerica, where small companion dogs played roles in cultural and spiritual life. The modern Chihuahua as we know it today was formally recognized by the American Kennel Club in 1904.
Despite being the tiniest of all recognized dog breeds, the Chihuahua has a personality that is anything but small. These dogs are intensely loyal, frequently forming a particularly strong bond with a single person in the household. They are alert, curious, and often quite bold around dogs and people much larger than themselves, which can occasionally require careful socialization management.
Chihuahuas come in two coat varieties, the smooth coat and the long coat, and are recognized in an enormous range of colors and markings. Their minimal grooming requirements, particularly in the smooth coat variety, make them a relatively low-maintenance breed in terms of coat care.
Key characteristics to know:
- Exceptionally loyal and devoted to their primary person
- Requires early socialization to prevent fearfulness or aggression toward strangers
- Sensitive to cold temperatures due to their small body mass and minimal body fat
- Long-lived compared to larger breeds, with many Chihuahuas reaching 14 to 17 years
- Can be stubborn, making consistent positive reinforcement training important from puppyhood
The world record for the smallest living dog by height belongs to a Chihuahua named Miracle Milly from Puerto Rico, who measured just 3.8 inches tall, underscoring just how extraordinarily small this breed can be.
2. Pomeranian
Height: 6 to 7 inches (15 to 18 cm)
Weight: 3 to 7 pounds (1.3 to 3.2 kg)
The Pomeranian is among the most visually distinctive of all the smallest dog breeds, instantly recognizable by its spectacular double coat that stands away from the body and frames the face in a characteristic fox-like expression. Despite its current toy size, the Pomeranian is descended from large Nordic sled-pulling dogs, and it was systematic selective breeding in the eighteenth century, particularly under the influence of Queen Victoria of England who was an enthusiastic Pomeranian breeder, that reduced the breed to its current compact dimensions.
Pomeranians are lively, alert, and genuinely intelligent dogs that tend to carry themselves with considerable self-confidence. They are naturally curious about their environment and retain a watchdog alertness that is somewhat surprising given their size. Their tendency to bark at perceived intrusions or unfamiliar sounds makes them effective little alarm dogs, though this quality requires management in apartment living situations.
The coat of a Pomeranian requires regular brushing to prevent matting and to maintain its characteristic full appearance, though they do not require professional grooming as frequently as some other small breeds. The double coat does shed, with more significant seasonal shedding occurring twice annually.
What makes Pomeranians particularly appealing as companion dogs:
- Adaptable to apartment living when their exercise needs are met
- Highly trainable and enjoy learning tricks and commands
- Sociable with familiar people but may be reserved with strangers initially
- Good with children who understand how to handle small dogs gently
- Available in one of the widest color ranges of any dog breed, including orange, black, white, cream, blue, and many parti-color combinations
3. Yorkshire Terrier
Height: 7 to 8 inches (18 to 20 cm)
Weight: Up to 7 pounds (up to 3.2 kg)
The Yorkshire Terrier, known affectionately by virtually everyone as the Yorkie, is one of the most popular small dog breeds in the world and has held consistently high rankings in AKC registration statistics for decades. Despite its current status as a glamorous companion breed, the Yorkie was developed in the nineteenth century in the textile mill regions of northern England, specifically bred to catch rats in the mills and mines of Yorkshire. This working heritage explains the feisty, determined, and tenacious character that sits just beneath the elegant exterior.
One of the most practically appealing characteristics of the Yorkshire Terrier is its coat, which is composed of fine, silky hair that grows continuously rather than a traditional double coat that sheds. This quality makes Yorkies one of the better options among small dog breeds for owners with mild dog allergies, though no dog breed is truly 100 percent hypoallergenic. The coat requires regular brushing and occasional trimming to maintain either the traditional long show coat or the more practical shorter puppy cut that most pet owners prefer.
Yorkies are smart, affectionate with their families, and surprisingly confident for their size. They respond well to positive reinforcement training and can excel in basic obedience and even agility activities. However, like many terrier breeds, they do have an independent streak that requires consistent and patient training from an early age.
Noteworthy Yorkshire Terrier characteristics:
- Low-shedding coat that produces less dander than many other breeds
- Highly portable and adaptable to urban living environments
- Bold and inquisitive, with a genuine terrier spirit despite toy breed size
- Forms strong bonds with family members and can be prone to separation anxiety
- Requires protection from cold weather due to their single-layer coat and small size
4. Maltese
Height: 8 to 10 inches (20 to 25 cm)
Weight: 2 to 8 pounds (0.9 to 3.6 kg)
The Maltese holds the distinction of being one of the oldest companion dog breeds in recorded human history. Depictions of small white dogs matching the Maltese description appear on ancient Greek amphoras dating to approximately 500 BC, and the breed was referenced by ancient Greek and Roman writers as a beloved companion of aristocratic women. This extraordinary historical longevity reflects how well-suited the Maltese temperament and size have always been to the role of human companion.
The most immediately striking feature of the Maltese is its coat, a flowing, silky white mantle that reaches the floor on show dogs and gives the breed an almost ethereal, floating appearance in motion. The coat is single-layered and produces minimal shedding, which along with lower dander production makes the Maltese another commonly recommended option for allergy-sensitive owners. Maintaining the coat in its full show length requires significant daily grooming commitment, while the practical puppy cut significantly reduces maintenance requirements for pet owners.
Beneath its delicate appearance, the Maltese is a genuinely playful, energetic, and often surprisingly bold little dog. They are deeply affectionate with their families and tend to be friendly and confident with strangers when properly socialized from a young age.
What prospective Maltese owners should know:
- Exceptionally gentle and well-suited to households with older children or adults
- Can develop separation anxiety when left alone for extended periods
- White coat requires regular cleaning around the eyes to prevent tear staining
- Responds very well to reward-based training despite occasionally appearing willful
- Long-lived breed with an average lifespan of 12 to 15 years
5. Toy Poodle
Height: Up to 10 inches (up to 25.4 cm)
Weight: 4 to 6 pounds (1.8 to 2.7 kg)
The Toy Poodle is the smallest of three officially recognized Poodle size varieties, alongside the Standard and Miniature. What many people do not realize is that beneath the elaborate show clips and elegant presentation, the Poodle is one of the most genuinely intelligent dog breeds in the world. Numerous canine intelligence studies, including the widely referenced work of Stanley Coren in The Intelligence of Dogs, rank the Poodle as the second most intelligent dog breed overall, behind only the Border Collie.
This exceptional intelligence makes the Toy Poodle highly trainable and genuinely enjoyable to work with in obedience, tricks, and even canine sports adapted for smaller breeds. They learn quickly, retain commands well, and tend to thrive on mental stimulation. Without adequate mental engagement, Toy Poodles can become bored and develop unwanted behaviors.
The Poodle coat is another defining characteristic. It is dense, curly, and grows continuously without a traditional shedding cycle. This makes Toy Poodles one of the most genuinely low-shedding breeds available, and one of the most commonly recommended options for households where dog allergies are a concern. The trade-off is that the coat requires regular professional grooming every four to six weeks to prevent matting.
Toy Poodle highlights for prospective owners:
- Ranked among the most intelligent of all dog breeds
- Minimal shedding coat with reduced allergen exposure compared to most breeds
- Highly adaptable to various living situations including apartments
- Athletic and energetic despite small size, enjoying walks, games, and training sessions
- Excellent with children and generally friendly with other pets when socialized early
6. Brussels Griffon
Height: 7 to 10 inches (18 to 25 cm)
Weight: 8 to 10 pounds (3.6 to 4.5 kg)
The Brussels Griffon is one of the most distinctive-looking of all the smallest dog breeds, with a broad, rounded head, large expressive eyes, and a flattened face that gives it an almost human-like expression. This unique appearance led to the breed gaining a cultural moment when the Brussels Griffon’s resemblance to the character Dobby from the Harry Potter films sparked widespread public interest in the breed.
Originally developed in Belgium in the nineteenth century, the Brussels Griffon was initially bred as a working ratter in city stables. Over time, the breed transitioned into a fashionable companion dog favored by Belgian nobility, including Queen Marie Henriette, whose patronage helped establish the breed internationally. It is recognized under three names depending on the registration body: Brussels Griffon, Griffon Bruxellois, and Petit Brabançon.
The breed comes in two coat types, the rough coat which has a wiry, dense texture, and the smooth coat which is shorter and lies closer to the body. Both require relatively modest grooming compared to long-coated small breeds.
Brussels Griffon temperament and ownership considerations:
- Deeply devoted to their owners and strongly prefer human company
- Does not cope well with extended periods of solitude and can develop separation-related behaviors
- Intelligent and curious, but can have a stubborn independent streak
- Generally better suited to adult households or families with older, calm children
- The brachycephalic facial structure requires attention to heat management and breathing in warm conditions
7. Papillon
Height: 8 to 11 inches (20 to 28 cm)
Weight: 7 to 10 pounds (3.2 to 4.5 kg)
The Papillon takes its name from the French word for butterfly, a reference to the breed’s most iconic feature: large, fringed ears that angle outward from the head in a way that perfectly mimics the spread wings of a butterfly in flight. It is one of the oldest toy spaniels in recorded history, with depictions of small butterfly-eared dogs appearing in European paintings dating back more than five hundred years.
What makes the Papillon particularly interesting among the smallest dog breeds is the combination of its delicate, elegant appearance with a genuinely athletic and highly capable working mind. Papillons consistently rank among the top performers in canine agility competitions across all size categories, regularly outperforming much larger breeds in speed and accuracy. This athleticism is matched by exceptional trainability that makes the Papillon one of the most responsive and rewarding small breeds to work with in any discipline.
The Papillon coat is long and silky with abundant feathering on the ears, chest, and legs, but despite its elaborate appearance the coat is surprisingly easy to maintain, requiring only regular brushing without the professional grooming demands of many other long-coated small breeds.
Key Papillon characteristics:
- Among the most trainable and agility-capable of all toy breeds
- Happy, outgoing temperament that adapts well to various family situations
- Relatively robust and energetic compared to other breeds of similar size
- Generally friendly toward strangers and other animals when socialized appropriately
- Available in both the upright-eared Papillon and the dropped-ear variety known as the Phalène
8. Russian Toy Terrier
Height: 8 to 11 inches (20 to 28 cm)
Weight: Up to 6.5 pounds (up to 3 kg)
The Russian Toy Terrier, formally known as the Russkiy Toy, is one of the least internationally recognized breeds on this list despite having a long history in its country of origin. Developed in Russia from English Toy Terrier stock imported in the early twentieth century, the breed was developed largely in isolation during the Soviet era, which created a population genetically distinct from its English relatives. The Russkiy Toy was granted full AKC recognition in 2022, making it one of the most recently recognized breeds in this comparison.
The breed exists in two coat varieties. The smooth coat variety has a short, close-lying coat that requires minimal grooming. The long coat variety has fringed ears and feathering on the tail and legs that gives it a more elaborate appearance while still remaining relatively low-maintenance compared to heavily coated breeds.
Russian Toy Terriers are elegant, energetic, and deeply devoted companion dogs. They are lively and enjoy playing but are also content to settle quietly with their owners, making them adaptable to a range of daily routines.
What to know about the Russian Toy Terrier:
- One of the lightest dog breeds in the world relative to height
- Very recently gained full AKC recognition, making finding reputable breeders important
- Loyal and affectionate but can be reserved with unfamiliar people
- Requires careful handling due to its extremely fine bone structure
- Both coat varieties are relatively low-maintenance
9. Japanese Chin
Height: 8 to 11 inches (20 to 28 cm)
Weight: 7 to 11 pounds (3.2 to 5 kg)
The Japanese Chin is one of the most ancient of all companion breeds, with a documented history spanning more than a thousand years in Japan, where it was exclusively the companion of the imperial court and aristocracy. Despite its name, the breed is believed to have originated in China before being introduced to Japan as a diplomatic gift to the imperial family, where it was then refined into the breed recognized today.
The Japanese Chin is frequently described as cat-like in its behavior, a characterization that resonates strongly with owners of the breed. Like cats, Japanese Chin tend to be fastidious self-groomers, enjoy perching on elevated surfaces, use their paws to wash their faces, and often have a quiet dignity and independence that distinguishes them from most other dog breeds. They are calm, gentle, and generally quiet indoors, making them one of the most suited of all small breeds for apartment living.
The silky, profuse coat of the Japanese Chin requires regular brushing but is surprisingly resistant to matting given its length and texture. The breed’s flat face places it in the brachycephalic category, which means heat management and avoiding strenuous exercise in warm conditions are important care considerations.
Japanese Chin ownership highlights:
- Exceptionally calm and quiet indoors, well-suited to apartment environments
- Gentle and well-mannered, excellent for households with elderly owners
- Cat-like self-grooming behavior reduces some coat maintenance demands
- Sensitive to heat due to brachycephalic facial structure
- Deeply devoted to family while maintaining an independent and graceful personality
10. Toy Fox Terrier
Height: 8.5 to 11.5 inches (22 to 29 cm)
Weight: 3.5 to 9 pounds (1.6 to 4.1 kg)
The Toy Fox Terrier, also known as the American Toy Terrier, is a distinctly American breed developed in the early twentieth century from small Smooth Fox Terriers selectively bred for reduced size. The AKC granted the breed full recognition in 2003. Like many terrier-derived breeds, the Toy Fox Terrier retains a working heritage that manifests as intelligence, energy, and a feisty confidence that belies its toy size classification.
One of the most charming historical associations of the Toy Fox Terrier is its long connection with circus performance. These dogs were widely used by circus clowns and performers throughout the mid-twentieth century, valued for their quick learning, ability to perform complex tricks, and natural playfulness that reads well in front of an audience. This history reflects genuine working intelligence and trainability that still defines the breed today.
The short, smooth coat of the Toy Fox Terrier is one of the lowest-maintenance coats among all small breed dogs, requiring only occasional brushing and bathing.
Toy Fox Terrier characteristics worth noting:
- Highly athletic and energetic relative to its tiny size
- Extremely intelligent and responds well to trick training and agility work
- Bold and confident, sometimes challenging with larger dogs if not properly socialized
- Loyal and affectionate with family, often forming particularly close bonds
- Minimal grooming requirements make it one of the most practical small breeds to maintain
11. Affenpinscher
Height: 9 to 11.5 inches (23 to 29 cm)
Weight: 7 to 10 pounds (3.2 to 4.5 kg)
The Affenpinscher closes our list of the smallest dog breeds in the world, and it does so with the kind of bold personality and distinctive appearance that makes it immediately unforgettable. The name Affenpinscher translates from German as monkey terrier, a reference to the breed’s broad, rounded face, prominent chin, large dark eyes, and shaggy coat that give it a distinctly primate-like expression. In France, the breed is affectionately known as the diablotin moustachu, or the moustached little devil, which captures its personality rather well.
Originating in Germany in the seventeenth century, the Affenpinscher was originally employed as a ratter in homes, stables, and shops, a working origin that explains the tenacious, bold, and occasionally stubborn character that persists in the breed today. Over time, selective breeding refined the Affenpinscher into the smaller, more refined companion dog recognized today, while retaining the confident and sometimes comical personality that makes it such an entertaining companion.
The wiry, dense coat of the Affenpinscher requires regular hand-stripping or trimming to maintain its characteristic texture and shape, which represents a moderate ongoing grooming commitment.
Key Affenpinscher traits:
- Confident, curious, and often genuinely funny in its behavior and expressions
- Can be stubborn and independent, requiring patient and consistent training
- Loyal to family but may be reserved or challenging with strangers
- Generally better suited to households with older children who understand dog boundaries
- Bold around other animals, requiring proper socialization from an early age
Breeds That Almost Made the List
Several additional small breeds were considered for this ranking and deserve mention for prospective small dog owners to research further. The Miniature Pinscher, sometimes mistakenly assumed to be a miniature Doberman, is a confident and energetic small breed with a fascinating history as an independent working breed. The English Toy Spaniel, also known as the King Charles Spaniel, is a gentle and quietly affectionate companion with a long aristocratic history. The Chinese Crested, available in both hairless and powder puff coat varieties, is one of the most distinctive-looking of all small breeds. The Shih Tzu, with its long flowing coat and famously friendly temperament, is one of the most popular small companion breeds in the world.
What to Consider Before Choosing One of the Smallest Dog Breeds
Selecting a small breed dog involves considerations that go beyond size alone. Several practical factors should inform your decision:
- Exercise requirements — Do not assume small dogs need minimal exercise. Breeds like the Toy Fox Terrier, Papillon, and Yorkshire Terrier have genuine energy needs that require daily walks and active play sessions.
- Fragility and household suitability — The very smallest breeds, including the Chihuahua, Toy Poodle, and Russian Toy Terrier, have fine bone structures that make them vulnerable to injury from rough handling or accidental falls. Households with very young children should factor this into their breed selection carefully.
- Grooming commitment — Coat type varies enormously across the smallest dog breeds. Short-coated breeds like the Toy Fox Terrier and smooth-coated Chihuahua require very little grooming, while long-coated breeds like the Maltese, Papillon, and Yorkshire Terrier require consistent grooming investment.
- Temperament and training needs — Many small breeds carry terrier or working heritage that produces bold, independent, and sometimes stubborn temperaments. All small breeds benefit from proper obedience training and consistent boundaries, regardless of their size.
- Lifespan commitment — Small dog breeds consistently outlive larger breeds. Many of the breeds on this list have average lifespans of 12 to 17 years, meaning adopting a small breed puppy is a commitment that can span nearly two decades of your life.
The smallest dog breeds in the world offer extraordinary companionship in compact, portable packages, but they deserve the same level of thoughtful care, proper training, and lifelong commitment as any other dog. Choose the breed that genuinely matches your lifestyle and energy level, and you will have a devoted companion for many years to come.
