Thank you Trinity. After I trimmed her up, I took the iodine and put in in the cracks and have been doing that once a week. Probably should do it several times a week.
I've aways been afraid of taking too much off the heel, perhaps when I go back out there later or tomorrow, I will take the rasp to her heels a few strokes on each side and see if that helps. I didn't take barely anything off the sole of her toe, it was just with the rasp to round off and file back the excess hoof wall. I wanted to work on the bars a little more, but my hoof knife is super dull...so I plan on going back to it with a sharpened hoof knife. :)
Thanks so much for your input, it's really appreciated!
