The tallest dog breeds in the world are led by the Irish Wolfhound, which stands a minimum of 32 inches at the shoulder — roughly the height of a kitchen counter. Other towering breeds include the Great Dane, Scottish Deerhound, English Mastiff, and Great Pyrenees. Below is a ranked height chart of the 12 tallest dogs, plus what life with a gentle giant really involves.
The 12 tallest dog breeds, ranked by height
"Tallest" is measured at the shoulder (the withers), not from the top of the head. Using recognized breed-standard heights for males, here are the 12 tallest dog breeds and their typical shoulder heights:
- Irish Wolfhound — 32+ inches
- Great Dane — 30–32 inches
- Scottish Deerhound — 30–32 inches
- English Mastiff — 30+ inches
- Anatolian Shepherd — 29+ inches
- Leonberger — 28–31.5 inches
- Great Pyrenees — 27–32 inches
- Borzoi — 28+ inches
- Saint Bernard — 28–30 inches
- Newfoundland — ~28 inches
- Neapolitan Mastiff — 26–31 inches
- Tibetan Mastiff — 26+ inches
Females in each breed generally run an inch or two shorter. Rankings shift slightly depending on the registry, but the order above reflects widely accepted standards.
Irish Wolfhound: the tallest dog breed
The Irish Wolfhound is the tallest dog breed in the world. As Britannica notes, males stand a minimum of 32 inches (81 cm) at the shoulder and females at least 30 inches (76 cm), with many individuals taller. Bred in Ireland to hunt wolves and large game, this sighthound combines immense size with a famously gentle, dignified temperament.
Despite their imposing stature, Irish Wolfhounds are calm, affectionate "couch giants" indoors. The Rover breed guide describes them as sweet-natured and people-oriented. The trade-off, common to the giant breeds, is a heartbreakingly short lifespan of roughly 6–8 years.
Other towering giants
Great Dane
The "Apollo of dogs" rivals the Wolfhound in height at 30–32 inches and frequently produces the world's tallest individual dogs. Danes are gentle, affectionate, and surprisingly mellow, but they are prone to bloat and heart disease.
Scottish Deerhound
A wiry-coated sighthound of 30–32 inches, the Deerhound looks like a larger, rangier Greyhound and shares the breed group's quiet, gentle disposition.
English Mastiff
At 30+ inches and often well over 200 pounds, the English Mastiff is the heaviest dog on Earth by weight while also ranking among the tallest. It is a calm, devoted guardian.
Anatolian Shepherd
A 29+ inch livestock guardian bred in Turkey, the Anatolian Shepherd is independent, protective, and notably long-lived for a giant breed at 11–13 years.
Leonberger and Great Pyrenees
The lion-like Leonberger (28–31.5 inches) is a friendly German working dog, while the Great Pyrenees (27–32 inches) is a majestic white mountain guardian famous for its calm, watchful nature.
Saint Bernard, Newfoundland, and the mastiffs
The alpine-rescue Saint Bernard (28–30 inches) and the water-loving Newfoundland (~28 inches) are beloved gentle giants. The wrinkled Neapolitan Mastiff (26–31 inches) and the ancient Tibetan Mastiff (26+ inches) round out the list as powerful, protective guardians.
Tallest vs. biggest vs. heaviest: what's the difference?
People often use "tallest," "biggest," and "heaviest" interchangeably, but they describe different things. Tallest refers to height at the shoulder, where the Irish Wolfhound leads. Heaviest refers to body mass, where the English Mastiff dominates — individual dogs have topped 200–250 pounds. "Biggest" is a loose term combining both.
According to Purina's overview of the world's largest breeds, a tall, lean sighthound like the Wolfhound can stand taller than a Mastiff while weighing far less. So the tallest dog and the heaviest dog are usually two different breeds.
Record-breakers: the tallest dogs ever measured
The tallest dog ever recorded is Zeus, a Great Dane from Michigan who measured 44 inches (1.118 m) at the shoulder in 2011, as verified by Guinness World Records. Standing on his hind legs, Zeus reached about seven feet four inches.
The "tallest living dog" title has passed between Great Danes ever since — including another Great Dane named Zeus from Texas, recognized at about 3 feet 5.18 inches (1.046 m) at the shoulder. Earlier record holders, such as Giant George, were also Great Danes, underscoring how this single breed dominates the height records even though the Irish Wolfhound is the tallest breed on average.

What to know before adopting a tall dog breed
Giant breeds are wonderful, but they come with outsized responsibilities. Key considerations:
- Shorter lifespans. Most giant breeds live just 6–10 years, a sobering trade-off for their size.
- Health risks. Deep-chested breeds are prone to bloat (gastric dilatation-volvulus), a life-threatening emergency, plus joint problems and heart disease.
- Cost. Everything scales up — food, medication doses, beds, crates, and veterinary care.
- Space and strength. These dogs need room and an owner who can physically manage a powerful animal.
- Early training. A giant breed must learn manners as a puppy, before it outweighs you.
This is general information only and not veterinary advice. If you are considering a giant breed, talk with your veterinarian and reputable breeders or rescues about health screening, especially for hips, heart, and bloat risk.
