If you’re looking for a dog breed that stays small forever, you’re in luck! Here’s a list of the best tiny dogs that don’t grow much beyond their puppy days.

Dog Breeds That Don’t Grow

1. Shih Tzu

The Shih Tzu, also known as the “Lion Dog,” is a small breed with a big heart. These charming little dogs were originally bred for Chinese royalty and still carry themselves with a regal, affectionate demeanor.

They typically weigh 9-16 pounds and stand about 9-10.5 inches tall, making them one of the best small dogs that don’t grow much. Despite their tiny size, their surprisingly sturdy build makes them great companions for families and individuals alike.

One of the standout features of a Shih Tzu is its long, flowing coat. While their hair can be styled in many ways, regular grooming is required to keep it from tangling. Many owners opt for a short “puppy cut” to make maintenance easier.

Their playful and affectionate nature makes them fantastic lap dogs. They thrive on human companionship and are incredibly loyal to their owners. They are also known for their friendly attitude toward other pets, making them a great choice for multi-pet households.

Even though they have a royal background, they are quite adaptable and happy in small apartments or big houses. They’re content as long as they have love, attention, and a comfy spot to nap.

2. Chihuahua

Chihuahuas may be the smallest dog breed, but their personalities are anything but tiny! Weighing between 2-6 pounds and standing only 5-8 inches tall, these little dogs are perfect for those who want a tiny companion with a big attitude.

Chihuahuas are famous for their bold, confident nature. Despite their size, they often act like they’re much larger than they really are, making them surprisingly good watchdogs.

They’re loyal and protective of their owners, sometimes to a fault. Socialization from an early age is essential to prevent them from becoming overly territorial.

One of the best things about them is their low-maintenance grooming. They come in two coat varieties—smooth and long-haired. Smooth-coated Chihuahuas need minimal brushing, while long-haired ones require more care to prevent tangles.

These dogs love being with their owners and prefer to be carried around or snuggled in laps. They form strong bonds and can suffer from separation anxiety if left alone too long.

3. Pomeranian

Pomeranians are tiny balls of fluff with huge personalities. Weighing between 3-7 pounds and standing about 6-7 inches tall, these pint-sized pups bring energy and charm wherever they go.

Hills Pet says these dogs are packed with confidence despite their small stature. They are lively, curious, and love to be the center of attention. Their extroverted nature makes them excellent companions for social dog owners.

One of their most distinctive features is their thick double coat. While their fluffy fur gives them an adorable appearance, it also requires frequent brushing to prevent mats and tangles. Many owners opt for a “teddy bear cut” to make grooming easier.

Pomeranians are surprisingly intelligent and enjoy learning tricks. Despite their tiny size, their sharp minds make them great candidates for agility training.

The Pomeranian is an excellent option if you want a playful, entertaining dog with a luxurious coat.

4. Pug

Pugs may be small, but their charm is larger than life! These affectionate little dogs weigh between 14-18 pounds and stand about 10-13 inches tall, making them one of the sturdier small breeds that don’t grow much.

With their wrinkled faces and big, round eyes, this intelligent breed of dogs has an expressive look that melts hearts.

They are social, friendly, and love being around people. They thrive on companionship and are happiest when cuddling with their owners.

Unlike fluffy breeds, Pugs have short, smooth coats that require minimal grooming. However, their skin folds need regular cleaning to prevent infections.

They are also prone to obesity, so a healthy diet and moderate exercise are important.

They have fun-loving personalities and enjoy playtime but are just as happy lounging on the couch.

5. Maltese

Maltese dogs are the epitome of elegance in a small package. Weighing between 4-7 pounds and standing about 7-9 inches tall, these beautiful little dogs stay small forever.

Their most striking feature is their long, silky white coat, which requires regular grooming to maintain its beauty. Many owners keep their Maltese in a short “puppy cut” to make grooming easier.

Maltese dogs are affectionate and thrive on human interaction. They love to be pampered and are known for their gentle, playful nature. Despite their delicate appearance, they are surprisingly bold and confident.

These family dogs adapt well to apartment living and don’t need much space to be happy. As long as they’re close to their owners, they’re content.

If you want a small, affectionate, and hypoallergenic breed, the Maltese is a wonderful choice.

6. Papillon

The Papillon, named after the French word for “butterfly” due to its signature wing-shaped ears, is a tiny breed with a huge personality. Weighing 5-10 pounds and standing 8-11 inches tall, this toy breed remains small and elegant.

Omlet says that despite their delicate appearance, they are incredibly energetic and intelligent. They excel in agility and obedience training, often outperforming larger breeds in competitions. Their high energy levels mean they need daily mental and physical stimulation, making them perfect for active owners.

Papillons have a beautiful, silky coat that is relatively low-maintenance compared to other long-haired breeds. They do not have an undercoat, so shedding is minimal. However, their feathered ears, legs, and tails require regular brushing to prevent tangles. Unlike some small breeds, they do not require frequent haircuts; occasional trimming around the paws and ears keeps them tidy.

These little toy dogs are incredibly social and love being around their owners. They are affectionate and thrive in environments where they receive plenty of attention. While they are friendly with people, they can be reserved around strangers and may bark to alert their owners of anything unusual.

Papillons adapt well to different living situations, from apartments to large homes, as long as they get enough exercise and playtime. If you’re looking for a small dog that is highly trainable, energetic, and affectionate, the Papillon is an excellent choice!

7. Havanese

The Havanese is a charming, affectionate breed that stays small while offering a big heart. Weighing between 7-13 pounds and standing 8.5-11.5 inches tall, these fluffy little dogs were originally bred as companion animals for the Cuban aristocracy.

One of the standout features of the Havanese is their silky, wavy coat, which can grow long and luxurious. While their coat does not shed much, regular grooming is essential to prevent tangles and matting.

Many owners opt for a short “puppy cut” to make maintenance easier. Orvis says that regular brushing and occasional trims keep them looking their best.

These dogs are known for their playful and outgoing nature. They are incredibly social and thrive on human companionship. Unlike some small breeds that can be independent, Havanese dogs love being around people and do not like being left alone for long periods.

Their affectionate nature makes them excellent therapy dogs and wonderful companions for families, singles, and seniors alike.

They are intelligent and relatively easy to train, responding well to positive reinforcement. Their friendly and adaptable personalities make them ideal for apartments and larger homes.

They get along well with children and other pets, making them a fantastic choice for multi-pet households.

The Yorkshire Terrier, or Yorkie, is one of the most popular small breeds, known for its stunning silky coat and feisty personality. Weighing between 4-7 pounds and standing about 7-8 inches tall, Yorkshire Terriers, specifically bred for those who want a small but bold companion, are a MUST have for fun-loving families..

Teacup yorkies have long, fine, human-like hair that grows continuously. This makes them a great option for allergy sufferers, as they shed very little. However, their luxurious coat requires frequent brushing to prevent tangles and mats. Many owners prefer a short “puppy cut” for easier maintenance, while others love the traditional long, flowing look.

Despite their small size, Yorkies are known for their big personalities. They are confident, lively, and often act like they are much larger than they really are. Their boldness makes them great watchdogs, as they will alert their owners to any unfamiliar sounds or people. However, early socialization is important to prevent excessive barking or nervousness around strangers.

These little dogs are intelligent and highly trainable but can be a bit stubborn. They thrive on attention and love being pampered. While they are affectionate with their families, they can be independent and enjoy having their own space.

Yorkies adapt well to apartment living and do not require a large yard, but they still need daily exercise and playtime. If you want a tiny dog with a huge personality and a glamorous coat, the Yorkshire Terrier is a fantastic choice!

VCA Hospitals says their ears, in particular, need extra care to prevent dirt buildup and infections.

Cavaliers are known for their gentle, affectionate nature. They are incredibly loving and thrive on human companionship, making them excellent lap dogs. Unlike some small breeds that are overly independent, Cavaliers love to always be with their owners. They are social and get along well with children, other pets, and even strangers.
