Another question...we have to help give a horse a betadine bath. The question is this: do we bath the horse first (shampoo/condition) and then do the betadine bath of 1/4 cup betadine with 1 cup water. Or do we not shampoo/conditon first and only do the betadine solution. Or am I completely out to lunch and there is another process to follow? Thanks for any help!
