What a Lucas Terrier’s height measures

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 10-12 inches. The listing describes an adult dog, not a growth chart for puppies.

Ranked by the tallest height its standard names (12 in), the Lucas Terrier is the joint 35th smallest of the 297 dog breeds on this site. See the smallest dog breeds ranked.

Drawn at the same 10 in: Lancashire Heeler, Australian Terrier and Cairn Terrier. Same drawing, different listings: a Lucas Terrier’s, a Lancashire Heeler’s and an Australian Terrier’s figures are each the lower end of its 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.
