Most people won't go for big dogs when adopting dogs; they'd probably pick small canines, thinking these small dogs require less effort to raise. However, that's not true. 

See, what people don't realize is that the largest dog breeds don't require much exercise. Given their size, large dogs are pretty calm inside the house, and all they need is a place big enough for them to move around.

All of this wouldn't matter as your heart will melt from their cuteness daily. Thanks to large dogs' slow maturation process, which will help you enjoy having your cute puppy for a long time.

Ranked as the heaviest dog breed in the world, Mastiffs outweigh all other dogs. An English Mastiff may reach 160–230 pounds and 30 inches in height, with females averaging 120–170 pounds and 27.5 inches.

However, they would be comfortable in apartments or small houses with yards if trained well. They’re highly adaptable, so they wouldn't be a burden if you ever wanted to move.

An English Mastiff would require daily exercise—just like any other dog—but it depends on their age and the air temperature (as their body temperature can rise quickly). 

Also, remember that they tend to be a bit lazy, and if you let them, they will gain a lot of weight.

They're very protective and aren't too open to strangers, making them good guard dogs, but when it comes to family, mastiffs are lovey-dovey dogs, making them good with little kids.

If you don't like dogs who drool, then you and an English Mastiff probably wouldn't be a great match, as they drool a lot.

Don't be fooled whenever they get referred to as one of the gentle giants. Great Danes are scary, vigilant dogs who aren't very open to strangers. 

Alongside their gigantic size, where the average male stands 30–32 inches tall and weighs 140-175 pounds, and females measure 28–30 inches and weigh up to 110–140 pounds: their bark is quite powerful and can scare away any intruder.

But they do become gentle giants with their families. Their personality is very far from being a couch potato. They are very playful and like to get a lot of love from their owners,  as they have a need for high mental stimulation.

Small houses or yards wouldn't be the best place for Great Danes due to their high energy levels; they need bigger space to exercise. 

Great Danes don't shed much, but they drool.

Saint Bernard is a strong and large breed, originally bred to assist monks passing through a snowy pass through the alps.

Despite being assertive dogs, they're easily maintained. A good long walk or half an hour of playtime is all this dog needs to be physically stimulated and healthy.

Saint Bernards are often characterized as intelligent, playful, and gentle personalities. Being initially bred as hospice dogs, they are very patient-friendly and warm.  

They love being around children, though it's not a good idea to be left with them unsupervised, as they may accidentally knock them over due to their size. Males can weigh anywhere from 140–180 lbs and 28 inches, while females are 120–140 lbs and 27 inches.

Being a large breed, they may suffer from health conditions such as hip and elbow issues, heart disease, and stomach bloats due to their deep chest that may be life-threatening.

They have a shedding season twice a year, during which daily brushing is a must. 

Otherwise, weekly grooming sessions are enough to keep their hair untangled and loose hair and dirt out of their coat. 

Heavy shedding during the shedding season would be a problem for people with allergies, and they should keep away from this breed.

They are prone to heatstroke and should always have a place to rest and lots of water nearby.

Considered one of the largest dog breeds, Labrador Retrievers males exceed 22 inches in height, while females are a tad shorter, reaching 21.5+ inches. Weight-wise, they can grow up to 65–80 pounds for males and 55–70 pounds for females.

According to the American Kennel Club, they are also known as America's favorite dog, even ranking number #1 most popular dog for 30 consecutive years.

They are a loving and easy-going breed, intelligent, and easy to train, making them great family dogs.

They originated from Newfoundland, where they were duck retrievers and fishers’ mates. Likewise, they have an extreme love for the water and webbed feet that allow them to swim fast, a thick water-repellent coat, and a powerful thick tail that can act as a rudder.

Labradors are excellent search and rescue dogs due to their high pain threshold, even though it might be difficult to tell sometimes when the dog is in pain. 

Originally used as farm dogs, they were used by farmers not just to protect and herd cattle but also to pull large carts to the market. They’re a tough and loving breed that is hardworking and very affectionate towards their companion.

Hailing from Switzerland: specifically from the canton of Bern, a place known for its vast valleys, high hills, and snowy mountains, this breed thrived in the cold and has an outstanding ability to work hard and stave off predators.

Known for their incredible strengths, a male Bernese Mountain Dog might grow over 25 inches and weigh around  80–115 lbs, whereas females might grow to be 23+ inches, 70–95 lbs. 

Their high energy levels require lots of maintenance and physical activity to keep them happy.

They are prideful and good-natured, though usually aloof towards strangers; they need early training and socialization sessions to become responsible and well-behaved.
