When comparing Scotch Collies side-by-side with show-line Rough Collies, what structural aspect contributes to the Scotch Collie appearing lighter in frame?
Answer
A slightly less pronounced 'stop' and a generally less heavy bone structure
Even when height comparisons are close, the Scotch Collie often presents with specific structural differences that contribute to it seeming lighter than a show-line Rough Collie. Key distinguishing features include having a slightly less pronounced 'stop'—the indentation where the forehead meets the muzzle—and possessing a generally less heavy bone structure throughout the body. These subtle skeletal characteristics result in a frame that looks leaner and more athletic, aligning with its functional heritage.
