The tallest dog breed in the world is the Irish Wolfhound, which the American Kennel Club recognizes at a minimum of 32 inches at the shoulder for males — about the height of a standard kitchen counter. Great Danes and Scottish Deerhounds compete closely behind. Below, we rank the 12 tall dog breeds you're most likely to meet at the park, with exact AKC height standards, real-world weight and lifespan figures, and what every prospective owner should know before bringing a giant home.
Tall dogs are different animals than simply "big" dogs. Saint Bernards and Newfoundlands can outweigh an Irish Wolfhound by 50 pounds, yet a Wolfhound stands two to four inches taller. If you're comparing breeds for living space, car size, or sheer head-turning presence at the trail, height — not weight — is the number that matters.
The 12 tallest dog breeds (ranked by AKC shoulder height)
All measurements are taken at the withers (the shoulder), using the official breed standard published by the AKC. Males are typically 2–4 inches taller than females.
| Rank | Breed | Male height | Weight range | Average lifespan |
|---|---|---|---|---|
| 1 | Irish Wolfhound | 32"+ minimum | 105–180 lbs | 6–8 years |
| 2 | Great Dane | 30–32"+ (preferred) | 140–175 lbs | ~10 years |
| 3 | Scottish Deerhound | 30–32" | 85–110 lbs | 8–11 years |
| 4 | Anatolian Shepherd | 29"+ minimum | 110–150 lbs | 11–13 years |
| 5 | Borzoi | 28"+ minimum | 75–105 lbs | 9–14 years |
| 6 | Leonberger | 28–31.5" | 110–170 lbs | 7 years |
| 7 | English Mastiff | 30"+ minimum | 160–230 lbs | 6–10 years |
| 8 | Great Pyrenees | 27–32" | 85–115 lbs | 10–12 years |
| 9 | Saint Bernard | 28–30" | 140–180 lbs | 8–10 years |
| 10 | Newfoundland | 28" | 130–150 lbs | 9–10 years |
| 11 | Neapolitan Mastiff | 26–31" | 110–150 lbs | 7–9 years |
| 12 | Tibetan Mastiff | 26"+ minimum | 70–150 lbs | 10–12 years |
1. Irish Wolfhound — the tallest dog breed
The Irish Wolfhound is, by AKC breed standard, the tallest of all recognized breeds. Males must stand a minimum of 32 inches at the shoulder, with 32–34 inches being typical and exceptional individuals reaching 35 inches or more. On their hind legs, a Wolfhound can comfortably look a 6-foot human in the eye.
Don't expect a guard dog. Wolfhounds were bred to hunt large game — wolves, elk, and Irish stag — but the breed standard describes their temperament as "courageous, dignified, calm." They're famously gentle with children and patient with strangers. The trade-off is a heartbreaking lifespan: most Wolfhounds live just 6 to 8 years, with heart disease and bone cancer being the leading causes of death.
2. Great Dane — the world record holder
The Great Dane is the breed that has produced every modern "world's tallest dog" record. Zeus, a Great Dane from Otsego, Michigan, measured 44 inches (1.118 m) at the shoulder in 2011, making him the tallest dog ever recorded by Guinness World Records. He stood 7 feet 4 inches on his hind legs. In 2024, a Great Dane named Kevin from Iowa briefly held the "tallest living dog" title at 3 feet 2 inches before passing away just weeks after being recognized.
The AKC standard calls for males at 30 inches minimum, "preferably 32 inches or more," and females at 28 inches minimum. Despite their size, Danes are easy-going couch dogs at home, but a 2024 UK lifespan study cited on Wikipedia pegs their average life expectancy at just 10.6 years, with dilated cardiomyopathy as a leading cause of mortality.
3. Scottish Deerhound — the regal sighthound
The Scottish Deerhound looks like a wire-coated Greyhound stretched to giant proportions. AKC standards call for males 30–32 inches and females 28 inches and up. They're the breed Sirius Black turns into in the Harry Potter films, and they've been owned by Scottish royalty for centuries.
Like Wolfhounds, Deerhounds are quiet, dignified, and largely unsuitable as guard dogs — they were bred to course red deer, not to bark. Read more about Hickory, the Scottish Deerhound who won Best in Show at Westminster, for a sense of the breed's quiet star quality.
4. Anatolian Shepherd — the working giant
The Anatolian Shepherd is the tallest of the livestock-guardian breeds, with males commonly reaching 29–32 inches. Originally bred in Turkey to protect flocks from wolves and bears, today they're used in the United States to guard endangered cheetah populations in Namibia and bighorn sheep in the American West.
Independent, territorial, and slow to mature, Anatolians are not city dogs. They need acreage and a job to do. Their advantage among giants is lifespan — well-bred Anatolians often live 11 to 13 years, far longer than most other dogs on this list.
5. Borzoi — the Russian wolfhound
Don't let the slim profile fool you: a male Borzoi stands at least 28 inches at the shoulder, with many topping 32 inches. Once known as the "Russian Wolfhound," they were the prized sighthound of the Imperial Russian court and were bred to course wolves across the open steppe.
Borzois are quiet, cat-like, and notoriously difficult to recall once a squirrel enters their peripheral vision. They're best suited to homes with a fully fenced yard.
6. Leonberger — the lion dog of Germany
The Leonberger was bred in 19th-century Germany to resemble the lion on the town crest of Leonberg. Males stand 28 to 31.5 inches and routinely weigh more than 150 pounds. They're water-loving working dogs with webbed feet — used historically as ship dogs and modern-day water rescue dogs.
Be warned: the Leonberger has one of the shortest lifespans of any breed on this list, averaging just 7 years. The trade-off is a dog famous for being calm, affectionate, and unflappable with kids.
7. English Mastiff — the heaviest dog on Earth
The English Mastiff (often just called "the Mastiff") isn't quite the tallest, but it's almost certainly the heaviest breed of dog in the world. Males stand 30 inches minimum and can weigh 230 pounds or more — Zorba, a 1989 English Mastiff, held the Guinness record for heaviest dog at 343 pounds. Despite their bulk, they're known for a serene, almost solemn temperament.
8. Great Pyrenees — the mountain guardian
The Great Pyrenees was bred to guard sheep in the Pyrenees Mountains between France and Spain. Males stand 27 to 32 inches at the shoulder under a thick white double coat. They're gentle with their family but bark — a lot — at perceived threats, which means they're better suited to rural homes than apartment living.
9. Saint Bernard — the alpine rescuer
The Saint Bernard is the most recognizable giant on this list, made famous by the monks of the Great St. Bernard Hospice who used them for alpine rescue starting in the 17th century. Males stand 28 to 30 inches and weigh 140 to 180 pounds. They drool prodigiously, shed seasonally, and snore loudly enough to compete with a small motor.
10. Newfoundland — the water rescue specialist
The Newfoundland is the swimmer of the giant breeds, with webbed feet and a water-resistant double coat. Males average 28 inches and 130 to 150 pounds. They were bred to work alongside fishermen in the cold North Atlantic, hauling nets and rescuing people who'd fallen overboard — a trait still used today in lifeguard programs in Italy and France.
11. Neapolitan Mastiff — the wrinkled guardian
The Neapolitan Mastiff descends from the ancient Roman war dog. Males stand 26 to 31 inches and weigh 110 to 150 pounds, with the breed's signature heavy folds of loose skin meant to deflect bites in combat. Today they're devoted house dogs, but their imposing presence still does most of the deterrence work.
12. Tibetan Mastiff — the ancient sentinel
The Tibetan Mastiff is one of the world's oldest dog breeds, bred for thousands of years to guard Himalayan monasteries from leopards and wolves. Males stand 26 inches or more and disappear under a thick double coat that doubles their apparent size. Independent and territorial, they're notoriously hard to train and best suited to experienced large-dog owners.
Tall vs. big vs. heavy: what's the difference?
Search results often conflate "tallest," "biggest," and "heaviest" — but to a giant-breed owner, these are three different categories:
- Tallest measures shoulder height (at the withers). Irish Wolfhound wins.
- Heaviest measures body weight. English Mastiff and Saint Bernard regularly top 200 pounds.
- Biggest is informal — usually a blend of length, height, and bulk. Great Danes typically win headline "biggest dog" coverage because their height and weight both register at the top end.
A Newfoundland and an Irish Wolfhound might weigh the same 140 pounds, but the Wolfhound stands four inches taller. If you're choosing a breed for the right SUV, the right doorframe, or the right couch, height is the number to plan around.
World records: the tallest dogs ever measured
The all-time tallest dog according to Guinness World Records is Zeus, a Great Dane from Otsego, Michigan, who measured 44 inches at the shoulder on October 4, 2011. He weighed 155 pounds and ate roughly 30 pounds of food every two weeks. Zeus died in September 2014 at age 5 — a stark reminder of the abbreviated lifespan most truly giant dogs face.
In 2024, Kevin, a 3-year-old Great Dane from West Des Moines, Iowa, was recognized as the tallest living dog at 3 feet 2 inches. Kevin passed away just two weeks later, and as of 2026 Guinness has not crowned a successor.
What to know before adopting a tall dog breed
Joints and growth. Tall puppies grow fast — sometimes adding two pounds a week. The American Kennel Club's large-breed nutrition guidance warns that high levels of calcium, phosphorus, and vitamin D — combined with excess calories — can trigger developmental orthopedic disease in giant-breed puppies, leading to hip dysplasia and osteochondrosis. Buy food labeled for large- or giant-breed puppies and feed several smaller meals daily to slow the growth curve.
Bloat (gastric dilatation-volvulus) is a giant-breed emergency. Deep-chested dogs like Great Danes, Irish Wolfhounds, and Mastiffs are at high risk. Don't exercise immediately after meals, consider a slow-feeder bowl, and ask your vet about prophylactic gastropexy (a stomach-tacking surgery) when your dog is spayed or neutered.
Lifespan reality check. Most of the breeds on this list live only 6 to 10 years. A Great Dane's heart, a Wolfhound's bones, and a Mastiff's joints all carry the burden of size. Plan for shorter, more intense ownership and budget for higher vet costs from the start.
The dog-friendly outdoors matters more. Giant dogs need long, low-impact walks rather than high-intensity sprints. A quiet trail or open field beats a crowded city sidewalk every time. Use the Sidewalk Dog directory to find dog-friendly parks and trails in your city where a Wolfhound can stretch out.
Frequently asked questions
What is the tallest dog breed in the world?
The Irish Wolfhound is the tallest dog breed by AKC standard, with males required to stand a minimum of 32 inches at the shoulder. Great Danes and Scottish Deerhounds occasionally produce individuals as tall or taller, but no breed has a higher official minimum height than the Irish Wolfhound.
Is the Irish Wolfhound taller than the Great Dane?
On average, yes. The Irish Wolfhound's minimum AKC standard is 32 inches for males, while the Great Dane's minimum is 30 inches (preferably 32 or more). However, the world record holders — Zeus and Kevin — are both Great Danes, because Danes have a wider height ceiling and produce more extreme outliers.
What is the tallest dog in recorded history?
Zeus, a Great Dane from Michigan, holds the Guinness World Record at 44 inches (1.118 m) at the shoulder, measured in 2011. He stood 7 feet 4 inches on his hind legs and died in 2014 at age 5.
How long do tall dog breeds live?
Most giant breeds live 6 to 10 years — significantly shorter than the average dog. The Irish Wolfhound averages 6 to 8 years, the Great Dane around 10, and the Leonberger about 7. The Anatolian Shepherd is the outlier on this list, frequently reaching 11 to 13 years.
Are tall dog breeds good with children?
Most tall breeds are excellent with children — Irish Wolfhounds, Great Danes, Newfoundlands, Saint Bernards, and Leonbergers are particularly known for patient, gentle temperaments. The main concern is size: a 150-pound dog can accidentally knock over a toddler simply by turning around. Supervision and basic obedience training are essential.
What's the difference between a giant breed and a large breed?
The American Veterinary Medical Association and most veterinary nutritionists classify dogs over roughly 90 to 100 pounds as "giant breeds," though some use 50 pounds as the threshold for "large." All 12 breeds on this list qualify as giant by either standard. Giant breeds have unique nutritional, exercise, and medical needs — particularly during puppyhood — that differ from standard large breeds.
Do tall dogs need more exercise?
Counterintuitively, no. Giant breeds typically need less high-impact exercise than medium-energy dogs like Border Collies or Labradors — too much can damage developing joints. Two moderate walks a day, plus access to a yard or open field for low-impact movement, is enough for most.
Find space for your giant dog
Tall dogs need room to stretch their long legs. Use the Sidewalk Dog directory to find dog-friendly parks, trails, and patios in your city — the kind of low-traffic, low-impact spaces a giant breed actually thrives in.
