I have a mostly white appyx. As someone else said about their white horse, she stays pretty "blinding white" clean in the summer b/c of the difference in the length and fullness of the coat ..the winter coat will collect more dirt, but it comes right off. Not to mention one is far more inclined to give them a bath in the summer than winter. ;) For other small stains I just spot spray it w miracle groom...always comes right out. She is pink skinned. I use a flymask and sunblock (nose only). However, she has never sunburned to my knowledge and I have been pretty vigilant about inspecting, and besides - she stays cooler than a black horse would. :)
I love white or greys! He looks sweet!
