The largest dog breeds in the world

Height, weight and build make these breeds impressive giants. Their size also brings particular responsibilities for care, space and feeding.

The largest dog breeds in the world

Which dogs are considered real giants - according to shoulder height, weight and overall appearance

When talking about the largest dog breeds in the world, it's not just weight or size alone, but a combination of shoulder height, body mass and overall appearance. Many of these giant dogs appear impressive - but are often surprisingly gentle in everyday life.

🐾 1. Great Dane

The Great Dane is considered the largest dog breed in the world by shoulder height. Individual animals even hold records as the “largest dog in the world”. Despite their size, Great Danes are usually calm, friendly and very people-oriented – real “gentle giants”.

  • Shoulder height: up to approx. 90 cm
  • Weight: 60-90kg

🐾 2. Irish Wolfhound

The Irish Wolfhound appears almost majestic with its enormous size. He is tall, slim and is considered to be particularly balanced. In terms of character, he is calm, sensitive and not very aggressive - despite his impressive appearance.

  • Shoulder height: up to approx. 87 cm
  • Weight: 55-85kg

🐾 3. English Mastiff

The English Mastiff is not necessarily the tallest dog in the world, but it is the heaviest. Some animals exceed the 110 kg mark. Mastiffs are alert, loyal and very calm - but they need responsible ownership and plenty of space.

  • Shoulder height: approx. 70-80 cm
  • Weight: up to over 100 kg

🐾 4. Saint Bernard

The Saint Bernard is known as an Alpine rescue dog. His size, strength and friendly nature made him world famous. Despite his massive body, he is usually good-natured, patient and family-oriented.

  • Shoulder height: approx. 70-90 cm
  • Weight: 65-120kg

🐾 5. Leonberger

The Leonberger combines size with elegance. His lion-like appearance appears imposing, but his personality is calm and balanced. It is considered family-friendly, but needs space, structure and appropriate feeding.

  • Shoulder height: approx. 65-80 cm
  • Weight: 60-80kg

🐾 6. Newfoundland

The Newfoundland dog is particularly broad and extremely strong. Originally bred as a water rescue dog, he is known for his calmness, friendliness and patience - even with children.

  • Shoulder height: approx. 66-71 cm
  • Weight: 60-70kg

🐾 7. Kangal

The Kangal is one of the largest and strongest livestock guardian dogs. He is extremely independent, alert and territorial. His size comes with enormous responsibility - he is not a beginner's dog.

Size alone is not enough - what matters for large dog breeds

  • Shoulder height: up to approx. 85 cm
  • Weight: 50-65kg

Large dogs have special needs:

Especially with giant breeds, an inadequate amount of food can lead to joint problems, obesity or stunted growth in the long term.

  • adapted feeding (not too high in energy, not too little)
  • controlled growth in young dogs
  • Pay attention to joint and bone stress
  • enough space & rest periods

Conclusion

The largest dog breeds in the world impress with their appearance - but size also means responsibility. Many of these dogs are calm, sensitive and highly focused on their people. What matters is not how big a dog is, but how well its needs are understood and met.

Find out which food and what amount of food really suits your dog

Especially for very large dogs, an individually calculated amount of food is crucial for joints, weight and long-term health.
