Which of these dogs is a sighthound breed?
The Irish Wolfhound is a historic sighthound dog breed from Ireland that has by its presence and substantial size inspired literature, poetry and mythology.
Like all sighthounds, it was used to pursue game by speed, it was also famed as a guardian dog, specializing in protection against and for the hunting of wolves. The original dog-type was presumed extinct by most knowledgeable authors but recreated specifically for the canine fancy mainly by Captain George A. Graham in the late 19th century.
Irish Wolfhounds are the tallest of all dog breeds, sometimes reaching 7 feet tall on their hind legs. They are well suited to rural life, but their medium energy profile allows them to adjust fairly well to suburban and urban life as well, provided they receive appropriate exercise.
Irish Wolfhounds are often favored for their loyalty, affection, patience and devotion. Although at some points in history they have been used as watchdogs, unlike some breeds, the Irish Wolfhound is usually unreliable in this role as they are often friendly toward strangers, although their size can be a natural deterrent. However, when protection is required this dog is never found wanting. When they or their family are in any perceived danger they display a fearless nature.
