What distinct herding technique, involving close contact, defines the function for which both Corgis were originally bred?

Nip-and-tuck style by targeting the hocks

Both the Pembroke and Cardigan Welsh Corgis were fundamentally bred to function as 'heelers,' meaning their primary herding utility involved close-quarters engagement with livestock, particularly cattle. The specific technique employed was known as the 'nip-and-tuck' style. This involved swiftly nipping at the hocks or heels of the cattle to encourage forward movement. The crucial countermeasure and survival mechanism inherent in this style was the dog's ability to instantly duck low to the ground beneath the swing of a retaliating hoof. This low center of gravity, promoted by their short legs, minimized injury risk while allowing them to effectively control the herd through physical management rather than relying on intimidation or distance work.
