Hi, well i have a pony kept at grass and recently she has been moved into a new field. She is usually quite clean and stays white, but lately her bum is getting really dirty. every time i bring her in, i have to was her thoroughly, and it really doesn't look very nice!
I think it could be because of all the long grass in the field, but it's strange because before when she has moved field it has never been a problem!
any help?
