Irish Wolfhound

The Irish Wolfhound, which is now more often found as family companion than bane of wolf pack, is described as having "great size and commanding appearance." He is the tallest of dogs, but not the heaviest. When full grown, a male Irish Wolfhound looms over other dogs, standing at least 32 inches tall and weighing 120 pounds. Females are a minimum of 30 inches and 105 pounds.
