I'm taking my mare to a week long show in a few weeks where she will be stalled all week, Last year when I took her I had to bath her everyday because she got absolutely filthy(beyond grooming) and I had to strip the stall down to the mats twice a day. This year I have a Lycra mane tamer and a sheet that fit her. However the sheet is a waterproof turnout sheet and this summer the highest temp was 110*F or close to that(In Michigan). Would I be able to leave it on her in the stall to keep her clean? Obviously taking it off when I groom her and exercise her and not put it back on until she is completely cooled down.
