Top 10 Largest Dog Breeds in the World

You have probably seen some really big dogs where you live, but what are the top 10 largest dog breeds in the world?

And what is the biggest dog in the world?

Let’s find out!

10. Leonberger

Height: 25.5-31.5″ (65-80 cm)

Weight: 90-170 lb (41-77 kg)


The Leonberger is a family-friendly and mild-tempered dog with its origins in Germany.

It’s a versatile worker that’s also used for search and rescue.

9. Newfoundland

Height: 26-28″ on average (66-71 cm)

Weight: 100-176 lb (45-80 kg)

Thanks to its sweet and gentle temperament, the strong and loyal Newfoundland is a great family dog.

It has webbed feet and a water-resistant coat which makes it an exceptional water rescue dog.

The Newfoundland is quite popular (ranks 35th of 194 breeds in the AKC), but not enough to make the top 10 most popular list.

8. Pyrenean Mastiff

Height: 25-31″ (63-79 cm)

Weight: 120-240 lb (54-109 kg)

Originally developed in northern Spain to protect livestock from thieves and predators like bears and wolves, the Pyrenean Mastiff is nowadays mostly used as a family dog.

7. Anatolian Shepherd Dog or Kangal Shepherd Dog

Height: 28-34″ (71-86 cm)

Weight: 88-185 lb (40-84 kg)

The Anatolian Shepherd Dog, also called the Kangal Shepherd Dog, is a very old breed from Turkey.

Because of its big size and powerful physique – and especially thanks to its intelligence, loyalty and protectiveness – it’s the perfect working guard dog.

6. St. Bernard

Height: 26-30″ (66-76 cm)

Weight: 120-180 lb (54-82 kg)

St. Bernard

The famous St. Bernard is a large rescue dog originating from the Swiss Alps, where it was bred by a monk brotherhood from the 18th century or earlier.

St. Bernards are great with kids as they are calm and patient.

5. Spanish Mastiff

Height: 28-35″ (71-89 cm)

Weight: 140-200 lb (63-91 kg)

The Spanish Mastiff (or mastín Español) is a powerful giant guard dog that was developed in Spain to protect farms and livestock from predators.

It’s calm, intelligent, and loyal to its family, but very determined when confronted by strangers.

4. Bully Kutta

Height: 30-34″ (75-86 cm)

Weight: 132-198 lb (60-90 kg)

Bred for hunting and guarding in Pakistan, the impressive Bully Kutta – or Pakistani Bully – is a supersized gladiator.

It’s intelligent, powerful and aggressive, and should not be handled by inexperienced owners. It’s unfortunately used in illegal dog fights.

3. Irish Wolfhound

Height: 30″ and up (76+ cm)

Weight: At least 105 lb (48+ kg)

Irish Wolfhound

The Irish Wolfhound is a very old breed that could have been brought to Ireland already 9,000 years ago.

It was originally bred for hunting and guarding purposes, but is today a very calm and social companion. Although it’s not the prettiest dog if you ask me.

2. English Mastiff

Height: From 27.5″ and up (70+ cm)

Weight: 120-250 lb (54-113 kg)

Massive and strong, the English Mastiff (or simply Mastiff) will deter most aggressors by simply showing up.

It can be fierce and courageous when protecting its family, but normally, it is docile and loving.

1. Great Dane

Height: 28-32″ (71-81 cm)

Weight: 110-180 lb (50-82 kg)

Great Dane

Originally a hunting dog, the tallest dog breed in the world – the Great Dane (or Deutsche Dogge) – is a friendly and social canine.

Because of its huge size and athletic physique, it’s sometimes called “Apollo of Dogs”.

Three very big dogs that almost made the list are BoerboelCaucasian Shepherd Dog, and Neapolitan Mastiff.

But these very small canines definitely didn’t make the list!

What’s the Biggest Dog in the World?

Depending on if you go by height or by weight, the record for the biggest dog in the world either goes to…

Zeus, a 44″ (111.8 cm) Great Dane from Michigan that sadly passed away in 2014.

Here’s a video of Zeus and his owner:

Or if you go by weight, the record goes to an English Mastiff named Zorba, the heaviest canine to ever roam the Earth.

At his heaviest in 1989, he weighed 343 lb (155.6 kg)! At the time, he also held the record for the longest dog at 8ft 3″.

(The picture below is from a previous world record.)
