The Irish Wolfhound is the tallest dog in the world, although individual Great Danes have occasionally surpassed it. As the name suggests, the breed was originally intended to hunt wolves, and they were very successful. There are very few wolves in Ireland today, and those that remain typically disguise themselves as snakes. Irish Wolfhounds also hunted elk, of which the few that remain disguise themselves as very big snakes.
Irish Wolfhounds were also used in warfare, being trained to knock knights off their horses and lick them until their armor rusted through, thereby making the knights easier for infantry to kill.
The breed is no longer used for hunting or warfare, since there's nothing left for it to hunt and the dog resents being used to transport either personnel or munitions. Modern Wolfhounds are generally employed as bridges or construction scaffolding.
