What historical event might predate the lineage of the Welsh Springer Spaniel?

Answer

Roman occupation

The history of the Welsh Springer Spaniel is suggested to stretch back centuries, potentially even predating the arrival of the Roman occupation in Britain. This deep anchoring in Welsh geography and history differentiates it from breeds developed much later. These dogs were evolved organically by countrymen over generations focusing purely on field utility rather than being created in a controlled, modern setting like a 19th-century laboratory, which speaks to their ancient roots within the region.
