How do you brush your horse correctly on Petz Horsez 2 for ds

use the first brush i think its red. and brush all over but leave dirt on so like only pull it around its whole body once.(if you dont know how to turn the horse its the two buttons on the back) then use the pink brush and leave a little bit of dirt on the horse then use the blue brush and get all the left over dirt if stars pop upit means you did it right i uasually leave the left over dirt on its butt.
