An Irish Terrier stands 18 in (45.7 cm) at the shoulder.
Height is measured at the withers, the top of the shoulders. The head and ears extend above that line. The American Kennel Club breed profile gives 18 inches. The listing describes an adult dog, not a growth chart for puppies.
Ranked by the tallest height its standard names (18 in), the Irish Terrier is the joint 91st smallest of the 297 dog breeds on this site. See the smallest dog breeds ranked.
Drawn at the same 18 in: Soft-Coated Wheaten Terrier, Australian Stumpy Tail Cattle Dog and Icelandic Sheepdog. Same drawing, different listings: a Soft-Coated Wheaten Terrier’s and an Australian Stumpy Tail Cattle Dog’s figures are each the lower end of its male range.
This is a published species or breed reference, not a prediction for an individual animal. Where a range is supplied, both ends appear with the reading. Shoulder height and head height are kept apart when comparing animals.
All 38 terrier dogs by height, tallest first, or every dog breed. To compare your own dog, measure it at the withers.
