Standard Medium Dog Breeds
1. Australian Shepherd
Personality: Highly intelligent, energetic, loyal companion
Vocal Level: Moderate (when they’re not busy working)
The Australian Shepherd is like that overachieving friend who seems to have endless energy and can do everything, and still look cool while doing it.
Standing at a solid 18-23 inches tall, these dogs are packed with muscles, sharp eyes, and a personality that screams, “Let’s do ALL the things!” Whether it’s fetch, agility training, or just learning new tricks, this breed is always up for a challenge.
They have a long, flowing coat with a variety of colors, including blues, reds, and merles. Their intelligence is off the charts, and they’re quick to learn commands (or figure out how to open the snack cupboard).
Be ready for a dog that needs mental stimulation, because if they’re bored, they’ll invent their own fun—usually by herding anything that moves.
Fun Fact: Aussies might not actually come from Australia, but they’ll definitely outsmart you in no time!
2. Basset Hound
Personality: Laid-back, affectionate, stubborn
Vocal Level: Low to moderate (until they start howling)
If the Australian Shepherd is your overachiever, the Basset Hound is your laid-back, relaxed cousin who has a serious sense of humor. They are instantly recognizable by those short legs, droopy eyes, long ears, and wrinkled appearance, they look like they’ve been doing “tired” for years.
Standing at 14 inches tall, Basset Hounds are short but sturdy. They were bred for tracking and have an incredible sense of smell, which means they’re pretty much professional sniffers.
They may not win any agility competitions (those short legs can be a hindrance), but they’ll definitely win you over with their sweet, gentle nature.
As per PetMD, Basset Hounds are calm dogs and may be content to sleep in their bed all day. Pet owners need to ensure they get enough exercise to avoid obesity and other health problems.
Basset Hounds are famously affectionate and love spending time with their humans, though they do have a stubborn streak. Be prepared for a slow-walking adventure if you’re taking them for a stroll—they prefer to follow their noses at their own pace!
Fun Fact: Basset Hounds have the perfect “sad face” down to an art, making it impossible to say no to their puppy dog eyes.
3. Airedale Terrier
Personality: Brave, confident, independent
Vocal Level: Moderate
The Airedale Terrier is like the Hercules of the terrier world—big, bold, and packed with confidence! Known as the “King of Terriers,” this breed is the largest of all terriers, standing tall at 21–23 inches.
With a distinctive wiry coat and that “serious” expression on their face, they look like they mean business. But don’t be fooled—they’re also loyal and affectionate with their families (if they feel like it).
Airedales were originally bred for hunting and water retrieving, so they’re naturally very energetic and love a good challenge. They have a keen nose and a brave heart, making them excellent working dogs.
However, they can be a bit independent, so don’t expect them to jump at every command. They prefer to think things through—probably because they know they look cooler when they act like they have a master plan.
Fun Fact: Airedales were used in both World Wars as messenger dogs, so they’re not just good-looking—they’re tough too!
4. Boxer
Personality: Playful, energetic, protective
Vocal Level: Low to moderate
If you want a dog that’s part class clown, part bodyguard, look no further than the Boxer! Standing at 21–25 inches and boasting a muscular frame, these dogs are strong, yet somehow manage to be the most adorable goofballs you’ll ever meet.
Boxers are known for their playful energy, affectionate temperament, and loyalty—they’re always ready to jump into action, whether it’s a game of fetch, a jog, or just a good ol’ belly rub session.
Their short coat and alert expressions make them look super athletic, but don’t let that fool you—these dogs are big softies at heart.
As per Hill’s Pet, Boxers typically don’t bark excessively, and if they do, it’s usually for a valid reason. However, many Boxers are naturally vocal and may make growling sounds that are simply their way of communicating.
Boxers are great with families and will protect their loved ones, but they’re also fantastic at making everyone laugh with their quirky antics. They can be a bit bouncy, so if you’ve got a lot of energy yourself, a Boxer might be your perfect match!
Fun Fact: Boxers are known for their “Boxer bounce”—a hilarious little hop they do when they’re excited!
5. Australian Cattle Dog
Personality: Intelligent, energetic, independent
Vocal Level: Low to moderate
The Australian Cattle Dog is like a high-powered sports car in dog form—fast, focused, and built for action. With a sleek, muscular frame and those sharp, alert eyes, pointy ears, this breed was made to work hard and herd cattle across vast, rugged lands.
Active and intelligent, these dogs are always on the move, so if you love a challenge, this dog might be your ultimate workout buddy. These dogs are available in two colors—blue and red speckle—and are commonly known as “Blue or Red Heelers.”
These medium-sized dogs are highly trainable but can be independent thinkers, meaning they need a firm, experienced owner who can match their energy. They’re incredibly loyal and protective, making them perfect working dogs or companions for active families. Just be prepared for some intense herding instincts—if you’ve got small children or other pets, expect this dog to try to “round them up” occasionally!
Fun Fact: Australian Cattle Dogs are also known for being “Blue Heelers” or “Queensland Heelers”, named for their ability to nip at cattle’s heels while herding them!
6. Bulldog
Personality: Relaxed, affectionate, determined
Vocal Level: Low
If there were an award for being “cool”, the Bulldog would be the undisputed champion. With their broad, muscular body and wrinkled faces, Bulldogs might look tough, but these athletic dogs are one of the gentlest breeds out there.
They are famously laid-back, enjoying a relaxed lifestyle that revolves around cuddling and lounging—but don’t let their chill vibe fool you. Bulldogs have a determined streak and are ready to jump into action when needed (especially when food is involved!).
They’re affectionate with their families and are incredibly loyal dogs, always sticking close to their humans. They might not win any marathons, but they’ll happily keep you company while you binge-watch Netflix. Bulldogs are also surprisingly good with kids and are known for their even temperament.
Fun Fact: Bulldogs were originally bred for bull-baiting (an old sport, thankfully banned), but now, they’re more likely to be found lounging on the couch than chasing anything down.
7. Bearded Collie
Personality: Friendly, energetic, playful
Vocal Level: Moderate
The Bearded Collie is the dog version of a walking teddy bear—fluffy coats, friendly, and always ready for an adventure. With that signature long, flowing coat, bearded look, and mischievous expression, these dogs are as adorable as they come. Energetic and intelligent, Bearded Collies are always up for a good game of fetch, a long hike, or just a fun romp in the yard.
Originally bred as herding dogs, they’re highly trainable and enjoy having a job to do, though they’d probably prefer that job to be something fun and active. These high-energy dogs are incredibly social and love being around people and other pets.
According to the AKC, these dogs can become bored quickly, so it’s important to keep training sessions engaging and varied. However, they do have a high grooming requirement due to their luxurious coat, so be prepared to brush them regularly. But it’s worth it—who could resist that fluffy face?
Fun Fact: Bearded Collies are often called “beardies,” and they were once known as the “working dog of the Scottish Highlands”—pretty impressive for a breed that loves to be cuddled!
