Medium-size dog breeds are a great option for many families. They're not too small or too large, offering you a perfectly sized dog for almost any home environment. Of course, every dog is different, but some breeds tend to have certain characteristics and behaviors. Overall, medium dogs make great apartment dogs for most people, but you must be willing to take them on walks if you don't have a fenced-in yard. 

Some people prefer medium dog breeds because you can play with them without worrying about them getting hurt due to their size. They also fit in almost any bed if you're the type of person that loves to sleep with your pets. Many medium-sized dogs are great companions, but temperament varies by breed and an individual dog's upbringing. Considering a medium-sized dog for your home? Keep reading to learn about the various medium-sized dog breeds. 

How Big Are Medium-Sized Dogs?

Medium-sized dogs are typically between 20 to 60 pounds

Medium-sized dogs typically weigh between 20 and 60 pounds.1 However, the exact size of your dog depends on their breed. Many breeds of dogs are considered medium-sized, including sporting, non-sporting, working breeds, terriers, and hounds.1 The medium-sized dog range is so broad that many separate it into three distinct categories:

  • Medium-small: Medium-small dogs are those on the lower end of the weight range, typically weighing 20-40 pounds, and they include beagles, corgis, and french bulldogs.
  • Average: Average medium-sized dogs typically weigh 40 pounds or more. This category includes the bulldog, Airedale Terriers, Australian Cattle Dogs, Basset Hounds, and German Pinschers. 
  • Medium-large: Medium-large dogs are between 40 and 60 pounds but are on the taller end of the spectrum, like Greyhounds. 

Medium-Sized Dogs That Are Good In Apartments

When looking for a medium-sized dog that can be happy and healthy in an apartment, you should look for dogs with calm and friendly temperaments. Depending on your lifestyle, you may also want a dog with low exercise needs unless you're willing to walk them multiple times a day. In addition, you may choose to find a dog that doesn't bark too often to avoid conflicts with the neighbors. Here are a few medium dog breeds ideal for apartment life: 

Chow Chow

  • Height: 17-20 inches
  • Weight: 45-70 pounds
  • Life span: 8-12 years

Chow Chows are on the larger side of the medium dog breed range. However, they make great apartment dogs because they housebreak easily and have a calm demeanor. They're affectionate dogs that are protective and fairly trainable. However, they don't have incredibly high energy levels, so they don't require as much exercise as other breeds. Instead, they'll be happy with a daily walk and indoor play with toys.2

Pembroke Welsh Corgi

  • Height: 10-12 inches
  • Weight: up to 30 pounds
  • Life span:12-13 years

One of the most popular breeds, the Corgi, is known for their affectionate demeanor and openness to strangers. Corgis are naturally protective but eager to please and easily trainable. While they're not exactly couch potatoes, they make great apartment dogs because of their size and love of hanging out with their humans.3

French Bulldog

  • Height: 11-13 inches
  • Weight: 28 pounds or less
  • Life span: 10-12 years

French Bulldogs, also known as Frenchies, are non-sporting medium-sized dogs that are affectionate, great with children, and good with other dogs.4 These dogs are easily trained and don't have high energy levels. In addition, they only bark to alert, making them a great option if you have neighbors.4

American Eskimo Dog

  • Height: 15-19 inches 
  • Weight: 25-35 pounds
  • Life span: 13-15 years

There are three versions of the American Eskimo Dog: a toy, miniature, and standard size. While all are great dogs, only the standard size qualifies as a medium-sized dog. However, no matter which size you have, they're a breed known to be incredibly loving, affectionate, and great with young children. However, they're not the best with other dogs, so socialization is key if you plan to have more than one pet in your life.5

Medium-Sized Dogs That Are Good With Children

If you have children, you should always look for breeds that are good with young children. However, any dog can be good with children as long as they're trained and socialized properly. Unfortunately, children may play too rough with small dogs, while large dogs don't know their own strength. Therefore, a medium-sized dog is typically best for households with children because they won't get easily hurt, and they won't accidentally cause injury or damage. 

Medium-sized dogs that are good with children

When looking for dogs that are good with children, consider breeds that enjoy being around people and those that are gentle and playful but not too loud. Medium-sized dogs that are good with children include: 


  • Height: 13-15 inches
  • Weight: 20-30 pounds
  • Life span: 10-15 years

Beagles are another popular dog breed because they're independent and do well with young children and other dogs. Beagles are hunting dogs, so even though they're known to be gentle with children, they still require physical and mental stimulation. These dogs are active and do well in homes with backyards, where they can play, dig, and run around.6


  • Height: 17-18 inches
  • Weight: 35-45 pounds
  • Life span: 12-15 years

Keeshonds are ideal dogs for families because they're affectionate, great with young children, and good with other dogs.

They still require regular exercise, but they're just as happy snuggling their pet parents on the couch after a long day.7

Cocker Spaniel

  • Height: 13.5-15.5 inches
  • Weight: 20-30 pounds
  • Life span: 10-14 years

Cocker Spaniels have big eyes and adorable floppy ears. They also make great family dogs because they're affectionate and great with children and other dogs. These dogs are easy to train but have a fairly high energy level, so you must be willing to give them mental and physical stimulation to prevent boredom and destructive behavior.8 


  • Height: 19-23.5 inches
  • Weight: 35-65 pounds
  • Life span: 12-14 years

The Samoyed is known for their fluffy white fur and perky ears. These dogs are affectionate and great with young children, but depending on their upbringing, they may not be great with other dogs. In addition, these dogs are friendly with strangers but have a high energy level and want to play throughout adulthood.9

Medium-Sized Dogs That Are High-Energy

High-energy dogs are ideal companions for those who have an active lifestyle. However, they're not the best first dogs for pet parents because they require tons of exercise and mental stimulation. However, having a high-energy dog comes with benefits; they can help keep you active and healthy because they'll want to engage in playing, walking, or running every day. Here are a few high energy medium-sized dog breeds: 

Border Collie

  • Height: 18-22 inches
  • Weight: 30-55 pounds
  • Life span: 12-15 years

Border collies are affectionate and do well with children and other dogs, but they're full of energy, so they require daily activity, including walks.

However, you can keep their energy at bay to prevent destructive behavior by giving them over an hour of vigorous exercise daily.10

  • Height: 20-23 inches
  • Weight: 40-65 pounds
  • Life span: 12-15 years

  • Weight: 35-60 pounds
  • Life span: 11-13 years

  • Height: 16-17 inches
  • Weight: 25-35 pounds
  • Life span: 10-15 years

  • Weight: 30-40 pounds

While these dogs are working dogs, they don't have energy levels as high as other dogs on this list, but they still need plenty of daily exercise. Additionally, because they're farm dogs, they have a strong prey drive and urge to chase, so they should have a fenced-in yard or walk on a leash.18

Caring For Medium-Sized Dogs

Properly caring for a medium-sized dog depends on their breed and current health. Every breed is different, but common health issues for these dogs include joint, eye, skin, and heart issues. Before adopting a medium-sized dog, always learn about their risk factors for certain health issues since every breed is different.1

Along with issues to look out for, you should care for your dog's health by taking care of all of their needs, including: 

  • Nutritional needs: Dog nutrition is key to their health and wellness. Medium-sized dogs are done growing around one year of age, but you'll still need to care for their nutritional needs by ensuring they eat a balanced diet. 
  • Medical needs: All dogs need annual vet visits and preventative care to get vaccines and tested for common health conditions, like heartworm. 
  • Mental stimulation: Mental stimulation is important for all dogs, especially those with high energy levels because it prevents boredom and anxiety. 
  • Physical exercise: Physical exercise also prevents boredom and anxiety while supporting total body health in dogs.

Frequently Asked Questions

Who is Dutch?

Dutch is an online veterinary pet telehealth service, created by pet parents and board-certified veterinary specialists. We use a science-backed approach to provide pets relief for their everyday physical and behavioral health issues. Dutch connects you with licensed veterinarians over video chat and messaging to help you get care for your dog or cat quickly wherever you are — without the stress or expense of a vet visit. We also partner with pharmacies who can deliver prescription medication (in applicable states only) and over-the-counter treatments directly to your door. Dutch isn’t a veterinary practice or pharmacy, but a company that helps facilitate these services for pet parents to make veterinary care more accessible to all.

What is a visit with Dutch like?

When booking a video call with a vet, you'll be asked a few questions about your pet’s health issue. Depending on the issue, you may also be asked to fill out a longer questionnaire about their symptoms and share photographs of them so our veterinarians can better understand what’s going on. You’ll then pick an appointment time that works best for you.

During your video call, one of our licensed veterinarians will talk to you about the symptoms your pet is experiencing, ask you questions, review your pet’s medical history if you’ve provided it, and answer any questions you have. The vet will ask to see your pet and their environment. And they may ask you to perform some simple checks on them if needed.

After your video call, the vet will send you a message with a custom treatment plan to help your pet feel better, including a link to buy any recommended prescription or over-the-counter medications. Place your order and we’ll ship it free.

How much will it cost for Dutch to treat my pet?

The Dutch membership starts at $7/mo for unlimited access to the vet. No more long waits for appointments or surprise bills.

In addition to the base membership plan, our veterinarians may also recommend additional medication (Rx and/or OTC) that you will have the option of adding to your plan at an additional cost.
