Full-Grown Medium Dog Breeds
1. Australian Shepherd
Weight: 40–65 lbs
Height: 18–23 inches
Temperament: Energetic, Smart, Loyal
The Australian Shepherd is a versatile herding breed that thrives in fast-paced environments. Their agility and speed make them natural athletes, always ready for action.
They often form intense bonds with their humans and may follow them from room to room. This attachment makes them excellent companions, especially in active households.
With sharp instincts and quick reflexes, Aussies learn commands rapidly. Mental challenges like puzzle games and advanced obedience training are essential to keep them satisfied.
Their medium-length coat can be straight or wavy, typically featuring striking merle patterns. Brushing once or twice weekly helps manage shedding and maintains coat health.
Aussies aren’t content lounging all day—they need structure, purpose, and movement. Without these, they may become bored and turn to mischief to entertain themselves.

Despite their name, Australian Shepherds were developed in the United States to herd sheep and cattle on the ranches.
2. Border Collie

Temperament: Intelligent, Energetic, Focused
Border Collies are built for precision and performance. Bred for sheep herding, they are endlessly alert and responsive to every detail around them.
They have a distinctive stare—called the “eye”—used to control livestock. This intensity carries over to everyday life, where they watch their surroundings closely.
According to the AKC, these dogs do best with mentally demanding tasks. Trick training, scent work, or agility sports are great outlets for their problem-solving drive.
Their coat can be either rough or smooth, both types needing regular brushing. Shedding is moderate and more pronounced during seasonal changes.
Border Collies bond deeply but may seem distant toward strangers. Early social exposure helps them develop confidence outside their family unit.

Temperament: Easygoing, Affectionate, Stubborn
The Basset Hound is known for its unmistakable low-slung body and long ears. Originally bred to trail small game, it has an incredible sense of smell.
This breed is calm indoors and rarely in a rush. Bassets prefer leisurely walks and relaxed environments where they can explore scents at their own pace.
Though affectionate with family, they often have a streak of independence. Training takes patience, as they may ignore commands if something smells more interesting.
Their short coat is dense and needs weekly brushing to manage shedding. Droopy ears and skin folds should be cleaned routinely to prevent infections.
Families appreciate their steady temperament and good behavior with children. They tend to form deep bonds and enjoy lounging close to their people.

They are naturally nurturing and do especially well with children. Collies often act as quiet guardians, alerting their family to anything unusual.
Training is smooth with this breed—they pick up commands quickly and respond to kind guidance. Harsh corrections can hurt their sensitive nature.
Rough-coated Collies require frequent brushing to keep tangles at bay, while the smooth-coated variety is more low-maintenance. Regular grooming also keeps shedding under control.
With their gentle spirit and calm demeanor, Collies fit seamlessly into household routines. They thrive on companionship and often seek out time with their people.

Height: 17–20 inches
Temperament: Alert, Loyal, Independent
The Australian Cattle Dog was developed for endurance and drive. Bred to herd cattle across long distances, it’s a breed that never tires easily.
Compact and muscular, they move with purpose and react quickly to their surroundings. As per Britannica, their alertness makes them excellent watchdogs and field companions.
Training sessions should be brief and focused, as they respond best to structure and clear goals. Without direction, they may invent their own tasks, often involving mischief.
Their short, weather-resistant coat is easy to maintain. Brushing once a week helps remove dead hair, and occasional baths are sufficient for cleanliness.
These dogs form tight bonds with their families but aren’t overly needy. They do best in homes that provide space and responsibility.

Despite their tough appearance, Bulldogs are incredibly gentle and enjoy lounging beside their people. They’re often content with a short stroll and a long nap.
They do not require intense activity but benefit from consistent daily exercise to maintain a healthy weight. Their tolerance for heat and exertion is low, so indoor time is best during warmer months.
Bulldogs need special care due to their facial structure. Cleaning skin folds and monitoring their breathing helps prevent health complications.
They’re excellent apartment dogs, adapting well to smaller spaces and quiet routines. Loyal and easygoing, they thrive on companionship and consistency.
Fun Fact:

The Chinese Shar-Pei is best known for its deeply wrinkled skin and serious expression. This breed carries a calm, composed energy and often prefers quiet over chaos.
They aren’t overly affectionate but bond tightly with those they trust. Their loyalty is strong, and they tend to choose one or two people as their inner circle.
Shar-Peis do well with firm, respectful training. While not naturally eager to please, they respond to calm routines and predictable leadership.
Grooming needs are minimal for their coat, but the folds require regular cleaning. Moisture buildup can easily lead to skin issues if ignored.
These dogs aren’t highly social with other pets and are wary of strangers, which makes early socialization essential.
Though low-energy, they enjoy short walks and structured play. Mental calm is just as important to them as physical activity.
Fun Fact:
Shar-Peis were once so rare that they were listed as one of the world’s rarest dog breeds in the 1970s.

Not one to seek constant attention, the Chow bonds on its own terms. With family, they’re dependable—but they prefer their space respected. Hill’s Pet states that they may not be affectionate to strangers or other dogs.
Early exposure to new experiences helps round out their temperament. Without it, they may grow overly wary or territorial.
This breed’s thick double coat demands consistent upkeep. Weekly brushing helps control matting and heavy seasonal shedding.
Chows are naturally independent thinkers. Training works best with steady, patient guidance rather than firm correction.
They appreciate calm environments and steady routines. High-energy households may overwhelm them or spark reactivity.
Fun Fact:
The Chow Chow has a unique stilted gait that gives it a distinct, almost regal walk.
9. Dalmatian
Weight: 45–70 lbs
Height: 19–24 inches
Temperament: Energetic, Outgoing, Intelligent
The Dalmatian is packed with personality and motion. Originally bred to accompany horse-drawn coaches, their love for movement is deeply ingrained.
They do best in homes where activity is part of daily life. Without structured play or exercise, their restlessness can escalate quickly.
Bright and eager to learn, Dalmatians take well to training, especially when it’s fast-paced and engaging. Repetition can bore them, so variety is key.
This breed thrives around people and tends to be outgoing. They’re affectionate with family and can be protective if the situation calls for it.
Short coats make grooming easy, but the breed sheds year-round. Brushing several times a week helps manage the hair.
Mental enrichment is as important as physical exertion. They enjoy puzzle toys, advanced commands, and off-leash exploration in safe spaces.
