Hi...I am a new horse owner and my mare has a touch of 'rain scald'..In her former barn, she was turned out at night and in during the day for lessons, etc. Essentially, she was never in the sunlight. I have been bathing her 2x week with a ivory liquid/iodine bath, and then using MTG on her. So far so good, but how long do I keep the treatment up? Until all signs of it are gone? Poor girl really hates the smell of the MTG apparently...my mild-mannered mare really rolls her eyes when I bring the stuff out! Any advice would be welcome. Thanks. Oh...and yes, I do keep her in every minute of sun that I can!
