The Dorset Horn is the horned conservation population within the wider Dorset sheep story. Southwestern English foundations and later international spread should be distinguished from the development of polled Dorsets.

Dorset sheep developed in southwestern England and later became internationally distributed. Horned and polled populations now share a wider breed story, but the conservation entry here concerns Dorset Horn.

White faces, long bodies, and horns in both sexes characterize the horned type; ram horns are much heavier than ewe horns. Grazing and dual-purpose production belong to its agricultural identity. Horned animals should not be confused with modern polled Dorsets.

Horned Dorset continuity alongside the polled population

The Continental Dorset Club’s history reports Horned Dorset imports to the American West Coast in 1860. Horned animals remained the dominant American Dorset type until the development of Polled Dorsets in the 1950s.

The club describes the American polled strain as arising from a genetic mutation. Both populations share important Dorset characteristics, including maternal performance and reproductive flexibility beyond the usual sheep breeding season. Their shared breed name does not make their horn status or conservation populations interchangeable.

The preservation subject here is the horned population. Growth of the broader Dorset registry, which also includes polled animals, cannot alone establish the security of Horned Dorsets. Their distinctive identity combines the visible horns with the ancestry and working traits maintained within that population.
