Have you ever read the books by James Herriot, the vet?
In of the stories they treated a foundering pony by putting him in a creek, several times a day. I can't remember how long they soaked, but it wasn't constant.

I have read all those books. :-) I don't remember that part. It might help the symptoms.
Ah HA! THAT'S where I remember that from. I LOVED those books. I've got all of 'em. They don't make vets like that anymore.
This was made into a series when i was young and it was my favorite!
