I know W LloydThomas and Clifford LB Hubbard did some of the older research on the corgi breeds s  W LloydThomas mentioned the Teckel connection he called it Tekal and dated the breeds orgin to around  BC in papers he wrote some of which Ive read  As is typical in writings of that era his history is flowery and wordy and doesnt give specifics about the research  He does say that midCardiganshire is particularly wealthy in the remains of early Celtic fortifications source What the Modern Corgi Owes to its Cardigan Ancestors AKC Gazette October  and I can only guess that its from these remains that the corgi has been dated  Incidently it might be better to call the early corgi a livestock dog rather than a herding dog as it was more of a guardnot unlike the Rottweiler  Im curious what the reason for the doubt is thoughdoes the corgi just seem recent  I see no particular reason for skepticismCelts have been around for a long time
