How many types of Irish Setters are there?

Officially, there is one type of Irish Setter with an established breed standard for coat color, build, temperament, and gait. You may notice some informal variations in individual dogs depending on whether they come from a hunting or show line. 

A closely related breed is the Irish Red and White Setter, whose predominantly white coat with deep red patches contrasts with the Irish Setter’s entirely chestnut to mahogany-colored coat.
