What criterion did breed clubs prioritize over working utility for the modern Rough Collie?

Answer

Specific looks and aesthetic breeding priorities.

Enthusiasts argue that the divergence between the Scotch Collie and the modern Rough Collie occurred when breed clubs, such as the AKC, began focusing on standardization based on appearance rather than the original working utility of the stock. This led to selection pressures favoring specific looks, sometimes resulting in exaggerated traits, such as a more extreme muzzle shape, which contributed to success in the conformation show ring, moving away from the original functional blueprint.
