An active, lively and wiry appearance; plenty of substance but free of clumsiness. Neither cloddy nor cobby but showing a graceful racy outline.

There is a heedless, reckless pluck about the Irish Terrier which is characteristic. They develop a great devotion for their masters.

Good tempered, notably with humans, it being admitted, however, that he is perhaps a little to ready to resent interference on the part of other dogs.

Jaw strong and muscular, but not too full in cheek, and of good length. Foreface not dished or falling away quickly between eyes, delicately chiselled.

Shoulders fine, long and well laid back. Legs moderately long, well set from shoulders, perfectly straight, with plenty of bone and muscle; elbows working freely clear of sides; pasterns short and straight, hardly noticeable, the forelegs moved straightforward when travelling.

Bitches 46 cms (18 ins).

Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog.

Male animals should have two apparently normal testicles fully descended into the scrotum.
