10 Large Dog Breeds

A large dog can bring a unique sense of security and companionship to your home, but the search for the right dog starts with understanding the specific needs and temperaments that come with a larger pup. These dogs often require more space and exercise. They may also need specialized training or supplements.

Many factors influence a dog’s size, such as genetics, breed, diet, and lifestyle. While individual dogs may vary, large breeds generally weigh a minimum of 50 pounds and stand at least 24 inches tall. Their impressive size often brings a unique dynamic to the household, offering a sense of reassurance and strength.

If you are considering the adoption of a large dog, check out these 10 popular large breeds. From playful goofballs to dignified guardians, discover which one might be the perfect fit for your lifestyle and family.

Afghan Hound

The Afghan Hound is a large dog with a regal appearance, mostly thanks to its long, silky coat. It has prominent hips, an arched neck, large paws, and a ring-curled tail. The Afghan is not one of the most famous dog breeds and is often overlooked by potential dog owners. But they are incredible dogs!

Those interested in this breed must remember that behind that beautiful appearance is a hound dog, needing exercise and enrichment to avoid unwanted behaviors. They will also have higher grooming needs, so be prepared for the work (or the cost). However, someone who chooses an Afghan hound can expect a silly, playful, and loyal companion.

Bernese Mountain Dog

Bernese mountain dogs are versatile “working dogs” that originated in the farms of Switzerland. They were domesticated to pull carts, herd animals, and serve as watchdogs. As a result, these dogs are strong, calm, and easy to train. Bernese mountain dogs are also known for their incredibly friendly and affectionate personalities.

The Bernese Mountain Dog is also a great choice for families with children due to their calm, gentle nature. But, if you’re trying to avoid dog hair around the house, be warned—they are heavy shedders that will need regular grooming.

Great Dane

Great Dane breed lies in the green grass.

When someone mentions large dogs, the Great Dane is often the first dog that comes to mind. In fact, the world record for the tallest dog is held by Zeus, a Great Dane that grew to be 44 inches tall. But this breed offers much more than just their impressive height.

Great Danes are generally friendly and affectionate dogs. They are surprisingly patient and usually make friends wherever they go, making them a good choice for anyone with a more social lifestyle. But bring them home, and you will see their inner watchdog come out as they always keep an eye open to keep their family safe.

Greyhound

The English Greyhound, or simply the Greyhound.

There is no denying that the Greyhound is a dog built for speed. With their athletic, aerodynamic bodies, they are known as one of the fastest dog breeds. Despite their ability to reach impressive speeds, they are happy to spend most of their time lounging with their family.

The greyhound’s short, smooth coat doesn’t require much grooming. They have a natural instinct to chase, so be cautious if you have small animals like cats. Some will adjust and learn to coexist, but it’s not guaranteed.

Great Pyrenees

The Pyrenean Mountain Dog is a breed of livestock guardian dog from France.

The Great Pyrenees is a dog historically bred to protect livestock like sheep and goats, as well as their human families. Their protective instincts run deep, making them the perfect breed for those searching for a watchful guardian of their home and loved ones. They require consistent training and socialization to learn how to interact appropriately with strangers and other animals.

These loyal and devoted dogs are also fiercely independent, making them difficult to train, especially for inexperienced dog parents. Like many dogs bred to survive outdoors in the colder months, they do shed, so be prepared for regular grooming to keep their thick coats in good shape.

English Mastiff

The English Mastiff, or just the Mastiff, is a dog revered for being heavy-boned, massive, courageous, and muscular. One of the most ancient dog breeds, the Mastiff’s lineage stretches back centuries. They were originally bred for guarding and protection, a role they still fill for many homes with their unwavering loyalty.

If you’re looking for a giant dog breed with the personality of a teddy bear, the Mastiff may be for you. They are known for being gentle and affectionate, forming strong bonds with their families. But their impressive size means making a few commitments, including plenty of space, specialized training, and a significant investment in food.

Newfoundland

The Newfoundland is a massive, powerful, and sweet-tempered dog breed. Originally bred as working dogs, they earned a reputation for cart pulling and water rescue skills. But that strength and intelligence, paired with their gentle nature, also makes them exceptional companions. Due to their calm and friendly nature, the “Newfie,” as they are affectionately called, can make an excellent choice for families.

With a thick coat to stay warm in less-than-ideal climates, Newfies are prone to shedding. Regular grooming is necessary to keep their thick coats healthy and minimize the amount of fur around the house.

Saint Bernard

Saint Bernards are among the most beloved and recognizable dog breeds worldwide, instantly recognizable for their massive size. Originating in the Swiss Alps, they were bred to do rescue work, navigating the rugged terrain. This is a testament to their strength and courage. But be prepared for shedding and drool… lots of drool!

However, these dogs are best known today for their calm, watchful, and patient nature. They are incredibly tolerant and affectionate, especially with children, earning them a place in the hearts of many as one of the best family-friendly breeds.

Leonberger

Another excellent dog for families with children, the majestic Leonberger is genuinely a versatile breed. They are strong, powerful swimmers with a natural instinct to help those in need, explaining their common use in water rescues and lifesaving. This breed has a beautiful appearance, from their lion-like mane to their large, bushy tail. But with this appearance comes a commitment to regular grooming.

Leonbergers form strong bonds with their families. Highly affectionate, they are often described as gentle giants, making them great companions for all ages. They are exceptionally calm and relaxed dogs, making them relatively easy to train.

Dogue de Bordeaux

The Dogue de Bordeaux, or the French Mastiff, is a powerful and muscular working dog. They originated from France and were bred to work pulling carts, guarding flocks, and hunting large game. Today, their strength and imposing appearance make them a great choice for many modern tasks ranging from guardian and protection roles to handling demanding physical labor.

Their size and muscular build might appear intimidating, but they are often surprisingly gentle and affectionate with their families. However, they are also a great choice if you’re searching for a dog to protect your home.
