Usually ermine spots on the legs are smaller. On the face they are called occluded spots. Cat tracks in body white. All are exclusions where the white pattern did not fully express.
There are many white patterns that are still not testable. You may come up with genes that are responsible for white but they may not be the gene responsible for the white on your horse.
I have a line of QH that all have ermine spots. Black on the bays, palomino on the palominos. The dam of my original stallion was a chestnut with chestnut colored ones. Not quite so big as that one but they all have several.
Some horse people change their horse, they change their tack and discipline, they change their instructor; they never change themselves.
