When it comes to choosing the perfect dog, size matters more than many people realize. Medium sized dogs are often considered the “sweet spot” of the canine world. They are not too small to feel fragile, yet not so big that they become difficult to manage in everyday life. Medium dogs usually adapt well to families, apartments, and even active urban lifestyles.
But what exactly counts as a medium sized dog? According to the American Kennel Club (AKC), medium breeds generally fall between 20–50 pounds (9–23 kg) and stand around 15–20 inches tall. However, in real life, the classification isn’t always so clear. Breeds like French Bulldogs, Pugs, and Corgis may be technically “small” according to AKC standards, but their sturdy frames and broad chests make them feel and behave more like medium dogs. Similarly, breeds like the Bichon Frise or Teddy (Miniature Poodle), while lighter in weight, often share lifestyle traits with medium breeds.
In this article, we’ll explore seven of the best medium sized dogs (and small-to-medium companions) that are ideal for families, city dwellers and dog lovers who want the perfect balance of size, personality, and manageability.
What Defines a Medium Sized Dog?
Before we dive into the breeds, let’s clarify what “medium” really means.
1. Weight and Height
Most guides classify medium dogs as those weighing 20–50 pounds with a shoulder height between 15–20 inches.
2. Chest Girth and Build
For many pet owners, chest size and body shape matter more than weight. A French Bulldog, for instance, may weigh under 28 pounds, but its broad chest often requires a medium-sized harness or dog clothing. Similarly, a Pug might weigh under 20 pounds, but many wear medium dog apparel due to their round and sturdy frames.
3. Lifestyle Fit
Medium dogs often have moderate exercise needs, enough energy to keep up with a family but not so much that they overwhelm city living. This balance makes them ideal companions for households with limited space.

French Bulldog - The Compact Companion
French Bulldogs have taken the world by storm, becoming one of the most popular breeds for city living.
- Size: Under 28 lb (AKC standard)
- Build: Broad chest, muscular, compact body
- Temperament: Loyal, affectionate, low-maintenance exercise needs
Why they’re considered medium: While technically small, Frenchies feel like medium dogs because of their sturdy build and personality. They’re calm, adaptable, and thrive in apartments, making them the ultimate city companion.

Pug - Small but Mighty
Pugs are proof that size doesn’t dictate personality. These little clowns of the dog world bring endless joy with their expressive faces and playful antics.
- Size: 14–18 lb
- Build: Round, muscular, deep chest
- Temperament: Loving, sociable, great with children
Although the AKC places them in the small dog category, many Pugs wear medium-sized harnesses and clothing due to their barrel-shaped chests. Their personalities also make them feel “bigger” than their size.
For families, Pugs are excellent because they adapt easily, require only short walks, and enjoy cuddling as much as playing.

Miniature Schnauzer - The Smart Small-to-Medium Companion
If you’re looking for a dog that combines intelligence, loyalty, and manageable size, the Miniature Schnauzer is a fantastic choice.
- Size: 11–20 lb
- Build: Sturdy, compact, wiry coat, terrier-like energy
- Temperament: Alert, affectionate, highly trainable
While the AKC classifies them as small dogs, many pet owners find that their robust frame and moderate exercise needs place them in the small-to-medium category in daily life.
Miniature Schnauzers are playful, adaptable, and protective without being overwhelming. They are also one of the more popular breeds for pet fashion because their chest girth often fits small or medium-sized apparel.

Corgis are one of the most recognizable breeds thanks to their adorable short legs and royal connections.

- Build: Long body, deep chest, sturdy
- Temperament: Playful, intelligent, affectionate, herding instinct
Technically on the small-to-medium border, Pembroke and Cardigan Welsh Corgis often require medium-sized harnesses and apparel due to their wide chests and long torsos.

Bichon Frise & Teddy (Miniature Poodle) – Small Dogs with Medium Lifestyle Needs
Both the Bichon Frise and the Miniature Poodle (often referred to as Teddy when clipped in a teddy bear cut) are technically small dogs, but they share many traits with medium breeds.
- Bichon Frise: 12–18 lb, hypoallergenic coat, cheerful companion
- Miniature Poodle (Teddy): 10–15 lb, intelligent, trainable, versatile
Why they’re included: Despite their small size, both breeds thrive in family environments, need moderate exercise, and often wear small-to-medium apparel depending on their build. Their grooming needs are higher, but their hypoallergenic coats make them excellent for households with allergies.
Choosing the Right Medium Dog for You
Medium sized dogs offer the perfect balance for many families: they’re sturdy enough to keep up with an active household but small enough to be manageable in city apartments.
Whether you’re drawn to the compact charm of the French Bulldog, the playful personality of the Pug, the true medium stature of the Schnauzer, or the cuddly nature of the Bichon and Teddy, there’s a medium-sized companion for every lifestyle.
When choosing, always consider:
- Your home space (apartment vs house)
- Exercise and grooming needs
- Compatibility with children or other pets
