How selective breeding transformed a white spaniel into a crimson icon

In short: The modern Irish Setter is famous for its vibrant chestnut coat, but its ancestors were far from uniform. From 16th-century hunting dogs to 18th-century Irish estates, discover how a preference for solid red colors fundamentally reshaped an entire breed.

While the breed is now synonymous with a deep red or chestnut coat, early literature suggests a much more varied palette. In 1570, Caius described 'setting' dogs in his work *De Canibus Britannicis* as primarily white with occasional red spots. By the mid-1400s, the breed's appearance was likely quite different, as the dogs Caius observed were likely a now-extinct type of setting spaniel. The solid red color we recognize today is believed to be the result of intentional selective breeding practices.

By the late 1700s, the Irish Setter had become a staple of the Irish gentry. Detailed stud records from the de Freyne family of French Park date back to 1793, alongside breeding efforts by notable figures like the Marquis of Waterford. While 19th-century observers like Youatt noted various colors including lemon and white-patched chestnut, the trend toward a solid red coat became dominant in the show ring. This shift created a divergence between the 'show-bred' Irish Setter and the 'field-bred' Red Setter.

This divergence led to significant tension in the dog world. Between 1874 and 1948, the breed's popularity in conformation shows was immense, producing 760 champions, yet only five achieved field championship status. This disparity eventually prompted outcrossing efforts in the 1940s, where breeders like Ned LaGrande introduced English Setter bloodlines to revive hunting capabilities. Today, the breed remains a study in contrasts, ranging from the larger, silky-coated show dogs to the smaller, more rugged working Red Setters.
