My farrier came out today (Jon Graham - I just love him), after having checked on Willie last week by himself while I wasn't here. He knew I had called and wanted to see how urgent it was. He said that what he saw put me at the top of his schedule.
We did nothing with his front feet; the shoes still look good. His back feet, the left one in particular, are a different matter. Quite flared and dropped sole. We agreed on taking off less more often... so Willie will be on a 3-4 week trim schedule for now. And, I am to call if anything doesn't look right in between trims.
Willie was very quiet and cooperative for him, though - that's nice to know.
Poor little guy. I hope we can get his feet and his weight sorted sooner rather than later and that he won't get too sore.
