Big dog breeds have uniquely different characteristics from each other. If you're struggling to work out which breed would work for you, take a look at our list of the most colossal canines in the UK:
The Great Dane is a large German breed of domestic dog. Also known as the Deutsche Dogge or German Mastiff.
They're one of the tallest breeds in the world. Their average height is 76-86cm, with the tallest Great Dane recorded to date coming in at an impressive 112cm! They are truly one of the most giant dog breeds you can buy today.
They can weigh between 54-62 kg, so you'll definitely know about it if one sits on your lap to have a snuggle.
Most Great Danes will be your gentle giant and make excellent family dogs; they love to play and can be downright goofy. They are relatively low-maintenance when it comes to grooming. However, they do need lots of daily exercise to stay healthy and happy.
Sadly, this big dog breed has a relatively short life expectancy of only 6-8 years.
A quiet giant breed of domestic dog that is a native breed to that emerald isle. The Irish Wolfhound averages a whopping 71cm in height and weighs around 40-69kg.
They were first referenced in literature in the 5th Century. They were originally bred specifically for Kings and noblemen to use when hunting deer, wild boar, and wolves.
Despite their wild beginnings, these days, they make lovable family pets. However, their size can sometimes be overwhelming for small children, so supervision is always advised.
Irish Wolfhounds are very vocal and have a loud, deep bark that can be heard from some distance away. They also have a high prey drive and need a lot of exercise and space to run around (a large garden is ideal).
These giant fluffy guys are one of the most popular breeds when it comes to large dogs and are originally from the Canadian province of Newfoundland and Labrador.
They were bred to help fishermen pull in their nets from the sea. Newfoundlands love the water and are strong swimmers, making them quite the active breed.
These days, their dense waterproof coat and webbed feet make them ideal for water rescue work.
Newfoundlands are one of the heaviest breeds of dogs, averaging around 55-80 kg in weight. They are also relatively tall, standing around 65-90 cm in height.
They are loyal, patient, and protective, which are ideal qualities in a family dog and make a great canine companion. They are an excellent choice for most prospective pet owners looking for a large dog due to their gentle nature, cute fluffy coat types, and excellent personalities.
Newfoundlands are professional 'droolers', so if you're looking for a neat and tidy dog, this is probably not the breed for you!
This massive breed hails from the Swiss Alps and was initially bred by monks for mountain rescue work in 980 AD. They got their name from the great Saint Bernard Pass in the Alps that connected Switzerland and Italy.
Saint Bernards are Switzerland's national dogs and were once known as 'barry dogs', named after one of the most famous Saint Bernards, Barry. He was quite the four-legged hero and is said to have saved over 40 people in his lifetime.
They are one of the heaviest breeds of dogs, weighing in at an average of 65-120 kg, and they're also one of the tallest, standing at 65-90 cm in height. That's a seriously big pup.
Saint Bernards are patient, gentle giants, but they can be a little overprotective. They need plenty of exercise and space, and their coat requires regular grooming to prevent mats and tangles.
Tibetan mastiffs are very independent dogs that need experienced handlers. They can be aloof and territorial with strangers and other animals and are not the best choice for first-time dog owners.
They are a powerful, muscular breed that was originally bred for guarding livestock and property in the Himalayan mountains.
Tibetan mastiffs weigh around 45-72 kg and can be 61-66 cm in height.
Their thick double coat means they need a lot of grooming because they are heavy shedders. They are also prone to health problems such as hip dysplasia, so regular check-ups with the vet are essential.
The Cane Corso is a large, powerful breed of dog from Italy. They were originally bred for hunting and guard work, but these days have adapted nicely to the role of a family pet.
These huge dogs weigh around 40-50 kg and are 60-70 cm in height. They have a short, dense coat that is easy to maintain, and they are moderate shedders.
They are loyal, protective dogs that usually bond with one person in the family and need firm, consistent training.
Their high prey drive also means they should not be trusted around smaller pets such as rabbits or rodents.
This massive muscular breed is so old that it's been around longer than France itself! It's thought that the Dogue de Bordeaux, or French Mastiff, was brought to France by the Romans.
These massive dogs weigh in at 57-68 kg and are 57-68 cm in height. They have a short, dense coat that is easy to maintain, and they are moderate shedders.
Proportionately, they have one of the heaviest heads of any dog breed, and their short muzzles make them prone to snoring.
The Dogue de Bordeaux breed was also famously brought to the world's attention in the 1989 film 'Turner and Hooch'.
The Rottweiler is a large, muscular breed that gets its name from the town of Rottweil, Germany, where they were bred and used to herd and guard cattle.
Their drive to herd things is still strong today, so don't be surprised if your Rottie tries to herd family members and other pets.
A powerful, loyal, and intelligent breed, Rottweilers are easy to train but need firm, consistent training from an experienced owner.
These powerful dogs weigh in at 35-60 kg and are 54-69cm in height.
Rottweilers are also known to be excellent guard dogs. However, their size and strength mean they can be a danger to smaller children and pets if not properly trained and socialised.
The Doberman was originally bred for guard work. They have an unfair reputation for being aggressive dogs, but this isn't quite true.
With the proper training and socialisation, Dobermans can be just as loving and devoted as any other pet and naturally form strong bonds with their families.
These regal dogs weigh in at 30-45 kg and are 60-70 cm in height. They have a short, dense coat that is easy to maintain, and they are moderate shedders.
Dobermans are one of the most intelligent dog breeds available, making them easy to train.
However, they need consistent training from an experienced owner because they can be a little stubborn.
The Bullmastiff is a cross between the Mastiff and the Bulldog. Nicknamed "the gamekeeper's night dog", they were bred to be guardian dogs for the estates of England and were a thorn in the side of poachers everywhere.
These days, Bullmastiffs are more likely to be found as loving family pets than out on the hunt for poachers.
Standing at 64-69 cm tall and weighing approximately 50-59 kg, they are not a small breed by any stretch of the imagination.
The Bull Mastiff is a large and powerful dog with a short coat that is usually fawn or brindle in colour.
They are calm, easy-going, and affectionate dogs with their families but can be protective and territorial. The bullmastiff is a true breed of family protector who will be a constant companion.
They also have an active lifestyle, and their size and strength make them a little too boisterous for small children, but they can be gentle giants with the proper training.
If you're thinking of adding one of these big dog breeds to your home, make sure you're prepared for all the responsibility that comes with owning one of these gigantic pups. They require a lot of exercise, space, and training, but the rewards of owning one of these beautiful dogs are more than worth it.
