The Llewellin Setter is regarded by some as a separate breed from the English Setter, while others contend that it is simply a particular strain within the broader breed. This variety was initially created by a Welshman named R. Purcell Llewellin, who obtained his breeding stock from Edward Lavarack, a breeder renowned for enhancing the English Setter. Furthermore, the Llewellin Setter includes a small amount of genetic influence from Gordon and other Setter breeds. This slight infusion has led to a Setter that is typically smaller, has shorter ears, and tends to remain closer to the hunter than those bred by Lavarack.
