7. Irish Wolfhound

The Irish Wolfhound holds the title of the tallest breed recognized by the American Kennel Club. Males stand a minimum of 32 inches at the shoulder, though many grow significantly taller. Historically used to hunt wolves and elk in Ireland, modern Wolfhounds have had the fierceness bred entirely out of them.

Today, they are serene, agreeable, and deeply sensitive animals. Because they are sighthounds, they possess a strong instinct to chase moving objects outdoors. Indoors, however, they are incredibly tranquil. They are quiet, observant, and deeply affectionate companions who prefer lounging on soft surfaces to protect their large, bony joints.
