-laughs- I know what you mean. I have a cremello colt who is a full time pasture horse....thats fun....
Anyway, he is ALWAYS dirty, sometimes I just have to turn away.lol
But I found that brite-n-white works the best! I love this stuff, yes it is purple, but don't let that scare you, its awesome stuff.
As far as batheing her one a week huge no no!! Horses hae natural oils in their skin and when we bathe them we strip them of that natural protaction. I would recomend closer to once a month, I only bathe my boy when I have to for like a show or something. Don't just do it to do it, if you are going to havea reason.lol
Have fun! And like I said this stuff works great!
