Great Dane vs. Irish Wolfhound: Height vs. Mass, Coat Maintenance, Lifespan & Gentle Giant Care
EXECUTIVE SUMMARY & 50-WORD DIRECT ANSWER SNIPPET
**Direct Answer for Search Engines & AI Overviews:** The Irish Wolfhound (Hound Group, 30-35+ inches, 105-180 lbs) is the tallest dog breed on average, featuring a rough wiry double coat, a sweeping Greyhound-like sighthound build, and zero human aggression. The Great Dane (Working Group, 28-34+ inches, 110-175+ lbs) holds individual Guinness height records, has a smooth single coat, and retains watchful estate-guardian instincts.
2. EVOLUTIONARY LINEAGE: GERMAN BOAR MOLOSSER VS. CELTIC WOLF SIGHTHOUND
Their group classifications reveal their completely different evolutionary engines. Despite its name, the **Great Dane** (*Deutsche Dogge*) is a **German Working Group Molosser** developed by German nobility from English Mastiffs and Irish Wolfhounds to hunt savage wild boar and guard baronial estates. The **Irish Wolfhound** (*Cú Faoil*) is an ancient **Celtic Sighthound (Hound Group)**—celebrated in Roman texts from 391 CE—built like a colossal, rough-coated Greyhound to sprint down and dispatch Irish timber wolves and giant elk by sight.

3. SILHOUETTE AND COAT CARE: SLEEK APOLLO OF DOGS VS. SHAGGY HIGHLAND WARRIOR
A **Great Dane** ('the Apollo of Dogs') is square-proportioned, regal, and statue-like with a blocky, rectangular head, deep square flews, and a razor-short, smooth single coat in Fawn, Brindle, Blue, Black, Harlequin (torn black patches on white), or Mantle. An **Irish Wolfhound** is longer-bodied with a deep chest and dramatically tucked-up sighthound waist, covered in a harsh, wiry, weather-resistant double coat (in Gray, Brindle, Red, Black, or Wheaten) with shaggy eyebrows and a distinguished goatee that requires weekly brushing and twice-yearly hand-stripping.

4. TEMPERAMENT & GUARDING INSTINCTS: 'GENTLE ON WHEN STROKED, FIERCE WHEN PROVOKED'
The ancient Gaelic motto of the **Irish Wolfhound** is *'Gentle when stroked, fierce when provoked'*, and toward humans, they are 100% gentle: as true sighthounds, Wolfhounds have zero territorial human guarding instinct—they are serene, soulful, quiet giants that never bark at the door. **Great Danes** are also affectionate '7-foot lapdogs' that try to sit on your sofa, yet because they belong to the Working Group, Danes retain an alert, protective estate-guardian instinct, a booming bark, and greater wariness toward uninvited strangers.
