These dogs are highly adaptable but thrive best in cooler climates thanks to their thick double coats. Their stunning tricolor fur and striking appearance make them stand out, but their loving personality is what truly makes them special. While they may seem reserved around strangers at first, their loyalty and devotion to their families shine through.
Bernese Mountain Dogs also have a working background. They were once farm helpers in Switzerland, excelling at tasks like cart-pulling and herding.

They are known as gentle giants who enjoy lounging more than running, often preferring quiet time with their people.

WebMD mentions that this breed developed in England during the mid-19th century by crossing mastiffs and bulldogs to guard estates and stop poachers. Their protective nature remains today, which makes them loyal guardians. While they can be wary of strangers, they are loving and kind toward their families.
Early training and socialization are very important for Bullmastiffs. With consistent guidance and positive reinforcement, their strength and natural instincts are shaped into confidence and good manners.

The Newfoundland is a large breed dog with a heart as big as its size. These dogs are gentle, patient, and famously affectionate, especially with children. The AKC states that their calm nature and protective instincts have earned them the nickname “nanny dog,” making them excellent companions for kids.
Bred on the Canadian island of Newfoundland, this breed was designed for hard work. With webbed feet and a waterproof coat, they became excellent swimmers, helping fishermen and even taking part in search and rescue operations. They can pull carts, swim with ease, and thrive in tasks that require strength and bravery.
Despite their working background, Newfoundlands are happiest when close to their families. They love snuggling on the couch, leaning against their people, and giving endless affection. Their long, dense coats do need regular grooming, but the love they give in return makes every brush worthwhile.

The Great Dane is a giant dog breed that often looks more like a small horse than a dog. These pups are known as the “Apollo of dogs,” as per PetMD, and are admired for both their majestic presence and gentle nature. Despite their size, they are playful, affectionate, and incredibly loyal companions who love spending time with family.
This breed has deep roots in Germany and England, where they were originally bred to hunt wild boar. Over time, they transitioned from fierce hunters to loyal family dogs, becoming especially popular on large estates. Today, their goofy personalities, long legs, and plop-anywhere attitude make them endearing pets that bring plenty of laughs and love to the household.
Great Danes are easygoing and relatively low-maintenance, needing little grooming and moderate daily exercise. Because of their enormous size, training and supervision are important from an early age—especially around young children who can easily be knocked over during play.

They are loyal companions who bond closely with family and are especially patient with children and other pets.
This ancient breed dates back nearly 2,000 years in Ireland, where they were used to hunt wolves and guard homes. With their long legs, sharp eyesight, and speed, they excelled as hunters. Over time, they shifted from fierce protectors to beloved companions, admired for their quiet and even-tempered nature.
Irish Wolfhounds need more space and exercise, making them better suited for large homes with yards. They enjoy long walks and chances to run freely, though they often grow into laid-back adults.

Known for their keen sense of smell and bravery, they could find stranded people, dig them out, and even lie on them to provide warmth until help arrived. Their courage and devotion made them legendary.
In the home, Saint Bernards are affectionate people-pleasers. They need space to move, regular walks, and early training to keep their large size manageable.
