Mastiffs have been around since ancient times, rubbing shoulders with warriors and guarding royal palaces. Originally bred as guard dogs, they were fierce protectors, but beneath that massive frame lies a heart of gold. Their history is as grand as their size, and they’ve earned their spot as one of the most loyal big dog breeds out there.
Towering at 30 inches and tipping the scales at a whopping 230 pounds, these big dogs are pure muscle with a side of droopy charm.

While they aren’t the life of the party, they’ll happily lounge around, keeping a protective eye on their loved ones with quiet confidence.
Despite their low-energy lifestyle, Mastiffs still need daily strolls to keep their joints healthy. Grooming is a breeze, but their love for lounging means owners should keep an eye on their diet. A few too many treats, and they might just tip the scales beyond their already impressive weight!

With a towering height of up to 30 inches and a weight that can reach 180 pounds, these giant dogs are as massive as they are lovable. Their thick double coat keeps them warm in freezing temperatures, and their droopy eyes give them a look of eternal kindness.

Caring for a Saint Bernard means keeping up with their energy bursts between long snooze sessions. They enjoy moderate exercise but won’t demand a daily marathon as mentioned in PetMD. Their thick fur requires regular brushing, and yes, drool comes as part of the package—consider it their version of a love note!

Whether pulling carts, watching over farms, or offering unwavering companionship, they’ve always been more than just a pretty face.
Weighing up to 170 pounds, the Leonberger carries itself with a proud yet friendly demeanor. Their thick, water-resistant coat gives them a luxurious look, but it also means shedding is a daily event.

A true gentle giant, the Newfoundland has been winning hearts for centuries. This ancient breed hails from Canada, where it was originally bred to assist fishermen—pulling nets, hauling loads, and even saving lives. With their natural swimming ability and webbed feet, these dogs are practically built for water rescues.
Massive yet graceful, Newfoundlands fall into the category of large dogs, often tipping the scales at 150 pounds. Their thick, water-resistant coat gives them an elegant appearance, but it also means shedding and drool are part of the package. Still, one look at their soulful eyes, and you’ll forgive them for the fur-covered furniture.
Newfies are affectionate to the core, often referred to as “nanny dogs” because of their protective yet gentle nature with children, as WebMD mentioned. They are affectionately called “Newfies” by those who love them, and for good reason—they form deep bonds with their families and thrive on human companionship.
These big-hearted dogs need plenty of space and exercise. Whether it’s swimming, hiking, or simply joining their humans on outdoor adventures, Newfoundlands are always up for an activity that keeps them moving. Despite their love for the great outdoors, they’re just as happy lounging by your side after a long day.

- Ideal for: Patient owners with extra couch space
- Temperament: Loyal, protective, and a little clingy
The English Mastiff has a history as colossal as its frame! Originally bred as fearless guard dogs, these gentle giants once stood beside warriors in battle. Now, they’ve retired from the battlefield and taken up a more important role—your oversized, drooling shadow.
Weighing in at over 200 pounds with a large stature that could rival a small horse, the Mastiff commands attention. But don’t let their size fool you—these big softies are known to lean on their humans for cuddles (and sometimes nearly knock them over in the process).
Despite their intimidating presence, Mastiffs have a strong sense of loyalty and a heart as mushy as their jowls. They adore their families and will do anything to keep them safe. Just be prepared for a dog that thinks it’s a lapdog, even when it’s half the size of your couch.
Mastiffs may not be zooming around like a Border Collie, but they still need enough exercise to stay fit. A few strolls and some lazy backyard lounging will do. And yes, expect an impressive amount of drool—keep those towels handy!

One of the oldest and most formidable guard dogs, the Tibetan Mastiff hails from the Himalayas, where it was bred to protect livestock and monasteries from predators. This ancient breed has long been revered for its strength, loyalty, and unwavering dedication to its family. With a presence as majestic as the mountains they originated from, these dogs are natural protectors.
Built like a fortress, the Tibetan Mastiff is a powerhouse among giant dog breeds, often weighing up to 160 pounds. Their thick double coat, which resembles a lion’s mane, provides insulation against harsh weather, but also means their shedding game is strong.
Independent and strong-willed, these dogs aren’t the type to follow orders blindly. They’re smart enough to think for themselves, which makes them both impressive and a challenge to train. Their loyalty to their family is unmatched, but they’re naturally wary of strangers, making them excellent watchdogs.
While they aren’t overly energetic, they do need regular exercise to stay healthy. A spacious yard is ideal, and mental stimulation is just as important as physical activity. Grooming requires commitment, especially during shedding season when their thick coat demands extra care. And if you’re looking for a quiet pet—think again.
Owning a Tibetan Mastiff isn’t for the faint of heart, but for the right person, they make the perfect companion. They thrive with owners who understand their independent nature and are willing to provide firm yet loving guidance.

The Bloodhound’s roots trace back to medieval Europe, where these scent-tracking marvels were cherished by monks and nobility alike. Originally bred for hunting and search missions, their noses are so powerful that their findings have even been used as legal evidence. A dog with a built-in GPS? Pretty much!
Towering over most puppies and even some full-grown dogs, Bloodhounds are solidly built and belong to the heavyweight division. They typically weigh between 80-110 pounds and carry a signature look—long, wrinkled skin, soulful eyes, and ears that seem to have a life of their own. But don’t let their droopy appearance fool you; they’re nothing short of athletic.
Sweet-natured and affectionate, Bloodhounds make for lovable companions. While they prefer following their noses over following orders, their gentle demeanor makes them great with kids. Just be prepared for some stubborn streaks—they like to do things on their own terms.
A Bloodhound’s life is all about activity. Whether it’s tracking scents for miles, exploring the outdoors, or simply perfecting their signature bark, these dogs require regular exercise and mental stimulation.
