The over-all appearance of the Irish Terrier is important. In conformation he must be more than a sum of his parts. He must be all-of-a piece, a balanced vital picture of symmetry, proportion and harmony. Furthermore, he must convey character. This terrier must be active, lithe and wiry in movement, with great animation; sturdy and strong in substance and bone structure, but at the same time free from clumsiness, for speed, power and endurance are most essential. The Irish Terrier must be neither "cobby" nor "cloddy," but should be built on lines of speed with a graceful, racing outline.
Long, but in nice proportion to the rest of the body; the skull flat, rather narrow between the ears, and narrowing slightly toward the eyes; free from wrinkle, with the stop hardly noticeable except in profile. The foreface must not fall away appreciably between or below the eyes; instead, the modeling should be delicate. An exaggerated foreface, or a noticeably short foreface, disturbs the proper balance of the head and is not desirable. The foreface and the skull from occiput to stop should be approximately equal in length.
Neck, Shoulders, Chest
Neck-Should be of fair length and gradually widening toward the shoulders; well and proudly carried, and free from throatiness. Generally there is a slight frill in the hair at each side of the neck, extending almost to the corner of the ear. Shoulders & Chest-Shoulders must be fine, long, and sloping well into the back. The chest should be deep and muscular, but neither full nor wide. Body- The body should be moderately long. The short back is not characteristic of the Irish Terrier, and is extremely objectionable. The back must be strong and straight, and free from an appearance of slackness or "dip" behind the shoulders. The loin should be strong and muscular, and slightly arched, the ribs fairly sprung, deep rather than round, reaching to the level of the elbow. The bitch may be slightly longer than the dog.
Should be strong and muscular; thighs powerful; hocks near the ground; stifles moderately bent.
Should be dense and wiry in texture, rich in quality, having a broken appearance, but still lying fairly close to the body, the hairs growing so closely and strongly together that when parted with the fingers the skin is hardly visible; free of softness or silkiness, and not so long as to alter the outline of the body, particularly in the hindquarters. On the sides of the body the coat is never as harsh as on the back and quarters, but it should be plentiful and of good texture. At the base of the stiff outer coat there should be a growth of finer and softer hair, lighter in color, termed the undercoat. Single coats, which are without any undercoat, and wavy coats are undesirable; the curly and the kinky coats are most objectionable.
Feet and Legs
The feet should be strong, tolerably round, and moderately small; toes arched and turned neither out nor in, with dark toenails. The pads should be deep, and must be perfectly sound and free from corns. Cracks alone do not necessarily indicate unsound feet. In fact, all breeds have cracked pads occasionally, from various causes.Legs moderately long, well set from the shoulders, perfectly straight, with plenty of bone and muscle; the elbows working clear of the sides; pasterns short, straight, and hardly noticeable.
