Smooth Collie

Picture Lassie with a short, easy coat and you have the Smooth Collie, a Scottish herding dog that Britain treats as a breed in its own right. It has the Rough's intelligence and gentle nature without hours of brushing, and it is quick to learn but sensitive to harsh handling. Registrations dropped to 29 in 2024 before recovering to 56 in 2025. Good breeders test for Collie eye anomaly and the MDR1 drug sensitivity carried in collie lines.
