The Irish wolfhound is the tallest of all the dog breeds. Its original purpose was wolf hunting, hence its name. The Irish wolfhound is specifically, a sighthound. The American Kennel Club describes the breed as: "Of great size and commanding appearance, the Irish Wolfhound is remarkable in combining power and swiftness with keen sight. The largest and tallest of the galloping hounds, in general type he is a rough-coated, Greyhound-like breed; very muscular, strong though gracefully built; movements easy and active; head and neck carried high, the tail carried with an upward sweep with a slight curve towards the extremity".
With such a massive dog, one would have to purchase a very large dog lounger! Quiet by nature, wolfhounds are generally quite aloof with total strangers. However with their family, wolfhounds develop very strong bonds. Irish wolfhounds become morose or destruction when left alone for extended periods of time. They are not aggressive towards other dogs however they often course other dogs due to their hunting history.
