The Irish Wolfhound is classified by The Royal Kennel Club within the giant ageing band, typically weighing 40–69 kg as an adult. The tallest dog breed in the world, the Irish Wolfhound was historically used to hunt wolves and guard estates across Ireland, and despite its imposing size is famously gentle and calm.
What this means for your Irish Wolfhound
The breed has one of the shortest average lifespans of any dog, with heart conditions — particularly dilated cardiomyopathy — and bone cancer (osteosarcoma) both significant risks. Bloat (gastric dilatation-volvulus) is also a major concern given the deep chest, so knowing the warning signs matters.
Given the breed's relatively short expected lifespan, regular veterinary check-ups from a younger age than you might expect for a dog this size can help catch issues early.
When is an Irish Wolfhound considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, giant breeds like the Irish Wolfhound are generally considered senior from around 5 dog years old.
