What unique characteristic defines the Welsh Springer Spaniel lineage that sets it apart from the English Springer ancestral line?
Answer
Distinctive red/white coat patterns
The Welsh Springer Spaniel has maintained a more separate and closed development path compared to its English cousin. While both share common Land Spaniel origins from the Iberian types, the Welsh line preserved specific identifiers. Most notably, the Welsh Springer is characterized by its distinct coat coloration, typically involving red and white markings. In contrast, the English Springer ancestry drew more heavily from the predominant black/white or liver/white spaniel populations prevalent in English hunting grounds, effectively solidifying the ESS identity as the principal large flushing spaniel in England, defined partly by its exclusion of the Welsh dog's specific coloring.
