TOP 10 Heaviest Dog Breeds In The World

Top 10 heaviest dog breeds

If you love dogs that are strong, heavy, powerful, and look like giants, then this will be the perfect list for you. So, what are these massive dog breeds?

Top 10 heaviest dog breeds in the world:

10. The Newfoundland

If you’re looking for a dog who is big and strong, but also gentle, then a Newfoundland dog might be the right choice for you.

These are dogs who:

  • Love children,
  • Love family and getting attention,
  • Possess an incredibly gentle temperament.

Newfoundland dogs usually weigh somewhere in the range of 59 – 82 kg (130 – 180 lbs), placing them in the tenth spot on our list.

9. The Saint Bernard

Saint Bernards are known as gentle giants.


They are calm, peaceful, and kind working dogs, famous for the role they play in helping rescue injured adventurers in the Alps.

Their usual weight ranges from 60 to 82 kg (133 – 180 lbs).

8. The Great Dane

Great Danes are yet another dog breed people like to refer to as “the gentle giants”. These dogs love their owners, and their owners love them.

And when it comes to height

…these giants are also known as the tallest dogs in the world. And although they may not always look like it, they also get quite hefty.

Great Danes can weigh anywhere from 54 to 90 kg (120 – 200 lbs).

7. The Bully Kutta

The Pakistani mastiff, perhaps better known as the Bully Kutta, is a large working dog that has been tasked with various roles. They have been utilized as guard dogs and hunters, and they even saw use in illegal dog fights.

The Bully Kutta usually weighs between 60 and 90 kg (133 – 200 lbs).

6. The American Mastiff

The American Mastiff is a huge dog whose appearance betrays its sheer strength and massiveness. On the other hand, their look sometimes bears a resemblance to their mighty ancestors, the English Mastiffs.

However, they also have the genes of…

…Anatolian Shepherd Dogs, along with personality traits to match. American Mastiffs will do everything in their power to protect the ones they love.

So, what about the weight?

Their loving nature doesn’t diminish their size; American Mastiffs can weigh 63 – 90 kg (139 – 200 lbs).

5. The Korean Dosa Mastiff

The Korean Dosa Mastiff, while somewhat less well-known, is still a large, loyal, and – you guessed it – massivedog.

They adore people, but it’s not necessarily a good idea to play with them a lot when they’re still puppies; their bones aren’t formed yet, and they grow quickly.

These dogs can reach up to 65 – 91 kg (140 – 201 lbs).

4. The Caucasian Shepherd Dog

Caucasian Shepherd Dogs are large guard dogs known far and wide as some of the best livestock guardians. They have pronounced territorial instincts, and are a particularly big and strong breed.

They can grow up to 76 cm tall, and they normally weigh 50 – 100 kg (110 – 220 lbs).

3. The Neapolitan Mastiff

As you can tell from many of my videos where this breed is mentioned, the Neapolitan Mastiff is a massive and ancient dog breed.

Their impressive appearance has brought them some bad luck in the past.

Most notably, they were used for dog fights in colosseums. Many countries restrict or outright outlaw their ownership even today.

Neapolitan Mastiffs usually weigh 59 – 100 kg (130 – 220 lbs).

2. The Spanish Mastiff

The Spanish Mastiff is a working dog with a long past of serving people as livestock protectors. They also happen to be a gentle breed, if somewhat massive!

Spanish Mastiffs weigh up to 60 – 100 kg (133 – 220 lbs).

1. The English Mastiff

Calm and polite, yet big, strong, and impressively massive pet in every sense of the word; it’s a good way to describe the English Mastiff.

These dogs possess…

…an impressive stature, growing as much as 70 – 90 cm tall, but what helps complement their truly massive size is, of course, their weight.

The weight of an English Mastiff can range from 60 to 110 kg (133 – 243 lbs).
