Irish Wolfhound

Also called Wolfhound, Cú Faoil

Once a hunter of wolves, the Irish Wolfhound is now a soft-natured giant that towers over every other hound.

The Irish Wolfhound is an ancient sighthound from Ireland, used for centuries to hunt wolves and deer and then rescued from near extinction in the 19th century. Today it is a calm, friendly giant with a short lifespan, a strong chase instinct and a big need for space.

Life with a Irish Wolfhound

Irish poems and sagas are full of great hounds, and the dog most people picture when they read them is the Irish Wolfhound. The legendary hero Fionn mac Cumhaill is said to have kept a hound named Bran, and the Roman consul Quintus Aurelius Symmachus is said to have written of seven Irish dogs that astonished Rome in the 4th century. Beyond legend, large rough-coated hounds were clearly prized in Ireland for hunting wolves, deer and elk, and were given as gifts between chieftains and kings.

The breed's history also includes a near ending. As wolves disappeared from Ireland (the last is commonly said to have been killed in 1786) and great estates declined, the hounds lost their work and their numbers shrank. By the mid-19th century they were very rare. Captain George Augustus Graham, a Scottish army officer, began gathering the remaining dogs in the 1860s and brought in Scottish Deerhound, Great Dane and Borzoi blood to rebuild the type. Since 1902 a wolfhound has marched with the Irish Guards as regimental mascot.

The modern Wolfhound is gentle, dignified and friendly, summed up by the old saying 'gentle when stroked, fierce when provoked'. Most are calm indoors, polite with visitors and easygoing with other dogs. They are affectionate without being clingy, and many like to lie in the middle of the kitchen floor where everyone has to step over them.

Living with one requires space, a large vehicle, a very big bed, and acceptance that the time together will be short. It also requires respect for the sighthound instinct: a Wolfhound that spots a running deer or cat may be gone before you finish calling its name.

A great match for

  • homes with a large, securely fenced garden
  • calm, adult-focused households
  • owners who want a quiet, friendly giant
  • people who can manage a large dog physically and financially

Think twice if

  • a lifespan of only about 6 to 8 years
  • strong chase instinct toward cats and small animals
  • needs a big car, bed and living space
  • prone to heart disease and bloat
  • a poor guard dog despite its size

Irish Wolfhound questions

How tall is an Irish Wolfhound?

Breed standards set minimum heights of 79 cm (31 in) for males and 71 cm (28 in) for females, and many dogs are taller. Males often stand around 81 to 90 cm (32 to 35 in). Up on its hind legs, a big male can rest its front paws on the shoulders of a tall adult. It is generally recognized as the tallest breed in the world.

Are Irish Wolfhounds good guard dogs?

Not really. Their size may deter some intruders, but most Wolfhounds are friendly with strangers and rarely bark. They were bred to hunt, not to guard property. If you want a watchful guard, choose another breed; if you want a calm, sociable giant that greets the postman with a slow wag, the Wolfhound fits.

Why do Irish Wolfhounds live such short lives?

Giant breeds age faster, and the Wolfhound is also prone to heart disease, bone cancer and bloat. The average lifespan is about 6 to 8 years, though some reach 10 or more. Choosing a breeder who screens for heart and liver problems, keeping your dog lean, and booking regular vet checks all help give it the best chance.

Can Irish Wolfhounds be let off the lead?

Only in securely fenced areas. As sighthounds, they react to movement and reach high speed in a few strides. Even a well-trained Wolfhound may ignore recall once a chase starts. Use a long line in open spaces, and let the dog run free only where it cannot reach a road, livestock or a neighbor's cat.

What is the difference between an Irish Wolfhound and a Scottish Deerhound?

The two share history, and Deerhound blood helped rebuild the Wolfhound in the 19th century. The Deerhound is lighter, slimmer and a little smaller, and is usually grey or blue-grey. The Wolfhound is heavier boned and more powerful, with a wider range of colors. Both are gentle, quiet sighthounds with strong chase instincts.
