Sable includes sable and sable and white. Black includes black, black and tan, tricolor and black and white.
Blue merle includes all blue merles, regardless of whether tan points are present or specified.
Note that this chart covers the period when those dogs appearing behind modern stock were imported to the United States. Many of the early blacks were black and white or black and tan, though those colors were rare by about the late 20's. There were no Shelties published in the Stud Book during the war years of 1918 and in the first years after 1941. However, virtually all of the importations that eventually had a strong influence on the American Sheltie had been made by 1941. The second short bar, for AN, had Tremont Patricia listed without a color given.
