 Irish or English Irish – In England , the Irish is standardized by the NFRS as an equilateral triangle of white with a side that begins at the chest , or between the front legs , and where the point ends mid length . In the United States and elsewhere , clubs like the AFRMA distinguish this marking as the English Irish and allow for another standardized Irish in which the rat may have white of an even or symmetrical nature anywhere along its underside .
