Rain Rot

[BeckeG@aol.com]

Help.  I don't know what to do any more.  We have a horse that has had some
form of Rain Rot for the past 6 months.  The vets said to use Betadine on it
until it is gone. But, it is not going away.  Some days it looks like it is
growing.

Does it get worse before it gets better?  I figure you folks have a wealth of
information that might help this horse.  Your insight would be appreciated.
Its funny, too. Because this little section of Michigan has had no rain for
over 2 months.  So how come "Rain" Rot is growing with no rain?
