The Irish Terrier has a graceful, racy outline, with a moderately long body. It should not have the short back characteristic of so many of the long legged terriers. It is sturdy and strong in substance, but it is also active and lithe in movement. This is an all-round terrier that must combine speed, endurance, agility and power to perform a great variety of jobs. Its broken coat is dense and wiry, never so long as to obscure the body shape. Its expression, like its nature, is intense.

Called the daredevil of dogdom, the Irish terrier is brash, bold, assertive, playful, inquisitive, independent, strong-willed and ever ready for action and adventure. It is usually aggressive toward other dogs and small animals and tends to be reserved with strangers. It likes to chase and run and hunt and explore; it needs daily physical and mental exercise in a safe area. Given sufficient exercise, it is surprisingly well-mannered and dignified indoors. It is a loyal and entertaining companion.
