Medium dog breeds between 20 and 40 pounds are a popular choice, especially for families with kids. Big dogs can be a bit intimidating, while pint-size pups can be a smidge too delicate. Medium-sized dogs, on the other hand, offer the best of both worlds. They are big enough to play and go on long walks with, but small enough to cuddle on the couch with.
If you’re looking for a dog that’s not too big or not too small, you might want to consider one of the amazing breeds below! From the active Brittany to the mellow Whippet, you’ll find exactly the right dog for your family on our list. Let’s dive in and check them out!
Content & Quick Navigation
Medium Dog Breeds Between 20 and 40 Pounds
Dogs are basically categorized into 4 sizes- small, medium, large, and giant. For reference sake, examples of these categories include:
- a Pomeranian is a small dog breed
- a Basenji is a medium dog breed
- a Rottweiler is a large dog breed
- and a Great Dane is a giant dog breed.
There isn’t really a single universally accepted scale, though. Ask 10 different dog experts what constitutes a “medium” breed and you’ll get 10 different answers. Some sources call anything under 35lbs a “small” breed, while others consider will tell you that a medium dog weighs anywhere from 15-50 lbs. I even have a friend who thinks that any dog weighing under 75 lbs is basically a toy breed!
Today, we’re focusing specifically on medium dog breeds, specifically ones that weigh in the range of 20-40 pounds.

Overall, the American Eskimo Dog is a delightful and playful companion that thrives on attention and mental stimulation.
Heads up: if you have allergies, the American Eskimo Dog (aka Eskie) is not the breed for you. He’s NOT hypoallergenic. He is, however, very kid-friendly!

Basenjis are independent and curious dogs, with a strong prey drive and a playful personality. They can be reserved with strangers and are often described as aloof or independent. They are highly intelligent but can also be stubborn, making training a bit of a challenge.
This breed requires regular exercise to stay healthy, but they are generally low maintenance when it comes to grooming. They are a healthy breed overall but can be prone to Fanconi syndrome, a type of kidney disease.
Overall, the Basenji is a unique and charming companion that requires a patient and experienced owner who can provide them with plenty of mental and physical stimulation.
3. Brittany
The Brittany hailed from the Brittany region in Northwestern France, in the 1800’s. They are the result of breeding English Setters with small Spaniels.

The Finnish Spitz stemmed from Finland, possibly as far back as 8,000 years ago. Since 1979, they have been Finland’s National Dog.

They are friendly and outgoing dogs that make great family companions. Finnish Spitz dogs are intelligent but can be stubborn and independent.
They are also very vocal dogs and love to bark. While that makes them great watchdogs, it also makes them less-than-ideal apartment dogs.

As far as medium dog breeds go, this sweet pup falls just a smidge under the AKC definition of “medium,” but he’s not quite what we would call a small breed, either. They are intelligent, energetic, and friendly dogs, making them a great choice for active owners.
Icelandic Sheepdogs are known for their loyalty and affection towards their families, but they can be reserved with strangers. They have a strong herding instinct and love to run and play, but they are also eager to please and can excel in obedience and agility training.
The breed is generally healthy dogs, but they can be prone to certain health issues such as hip dysplasia and eye problems (specifically distichiasis). They require regular exercise and mental stimulation to stay healthy and happy, but their thick, double coat requires regular grooming to prevent matting and tangling.

The true origin of the Kerry Blue Terrier is not known, although numerous theories have developed over the years.
What is known is that these dogs came from the County Kerry Mountains in Ireland and that these dogs were originally bred to control pesky animals, like badgers, foxes, rabbits and rats.

This energetic guy IS hypoallergenic.
11. Standard Schnauzer
Technically, both the miniature and standard schnauzer fall into the 20-40 lb range but are on complete opposite ends of the spectrum. Miniature schnauzers are technically considered a small dog breed and they max out at about 20 lbs.
Standard schnauzers, on the other hand, typically weigh between 30-50 lbs. So if you have a very strict weight limit that you need to stick to (I know some apartments leave very little wiggle room there), you may want to go with a mini.
- Height- 17-19″ for standard,12-14 for mini
- Weight- 30-50 lbs standard, 11-20 mini
- Lifespan- 13-16 standard, 12-15 mini

Oh, and they ARE hypoallergenic! Yay!
12. English Cocker Spaniel
The adorable & sweet Cocker Spaniel is the perfect choice if you’re looking for a loving lap dog that also knows how to have fun.

- Weight- 20-30 lbs
- Lifespan-10-14
- Coat Colors- Brown, black, tan, silver, and combinations of those colors
- Breed Group- Sporting
- Personality- Bright, affectionate, loving, mellow
These beauties are popular among both families and seniors alike thanks to their fairly laid-back personalities. They’re equally content chilling on the sofa with the grownups as they are playing a game of fetch in the backyard with the kids. They even get along well with other dogs!
13. Pembroke Welsh Corgi
Made famous by Queen Elizabeth II, the Corgi is an athletic pooch that’s incredibly affectionate without being clingy. As herding dogs, they do need a fair amount of exercise, but they’re also content to relax on the sofa with you after a long day.
- Height- 10-12″
- Weight- up to 30 lbs
- Lifespan-12-13
- Coat Colors- Black & tan, fawn, red, sable
- Breed Group- Herding

They may not look it, but Corgis are excellent watchdogs! These little guys once roamed the fields keeping sheep in line and making sure nothing attacked them, so they know how to raise the alarm when they sense danger.
14. Shetland Sheepdog (AKA Sheltie)
If you dream of owning a Collie but live in an apartment with a strict 40-lb weight limit, the Sheltie may be the dog you’re looking for. They share nearly all of the same traits (both personality and physical) but they’re half the size.
- Height- 13-16″
- Weight- 15-25 lbs
- Lifespan-12-14
- Coat Colors- Black & white, black white and tan, tan and white, sable merle
- Breed Group- Herding
- Personality- Extremely intelligent, eager to please, obedient, highly affectionate
Like Collies (including Border Collies), Shelties are herding dogs who are happiest when they have some sort of job to do. Make sure you play plenty of mentally stimulating games with them. They absolutely adore children and get along great with other dogs, but they do need obedience training to set boundaries. Otherwise, they’ll try to herd everyone and everything.
15. Beagles
We can’t forget the adorable Beagle with his soulful bark, now can we? These independent pups are perfect for a working family who wants a loving companion that also knows how to spend time on his own.
- Height- 13-15″
- Weight- 20-30 lbs
- Lifespan-10-15
- Coat Colors- Black & tan, brown & white, blue & tan
- Breed Group- Hound

Beagles are pretty vocal and high-energy dogs. They need plenty of mental stimulation, and their stubborn nature means that they’ll require a bit more effort on the training front. Still, their loyalty and zany antics make every moment of extra training totally worthwhile.
16. Bulldog
I saved the bulldog for last because only the females fit the “medium-sized dog breeds ranging from 20-40 pounds” criteria, and they only JUST make it.
- Height- 14-15 inches
- Weight- 40 lbs females, 50 lbs males
- Lifespan- 10-12 years

There are quite a few medium dog breeds between 20 to 40 pounds, but these get our vote for the top 10!
With a great mix of hypoallergenic dogs, active pups, and unique breeds, I bet you’ll find your dream dog here!

There are quite a few medium-sized hypoallergenic dog breeds, including the Wire Fox Terrier, the Schnauzer, Kerry Blue Terrier, and Tibetan Terrier. Noticing a trend? Quite a few members of the terrier group are allergy-friendly!
What are some medium dog breeds that don’t shed?
Again, terriers are your best bet, especially if you want a non-shedding dog that’s allergy-friendly. The Whippet is another great option if you don’t particularly need a hypoallergenic pooch. While they have real fur (non-shedders or mild shedders tend to have “hair” vs “fur), it’s very short.
What medium dog breeds live the longest?
There are several medium-sized dog breeds that are known to live longer than others. Here are a few examples:
-Australian Cattle Dog: These dogs can live up to 13-15 years on average.
