The horse had been in Softride Boots pretty much all the time since April 12 (except for hoofcare and throwing them once for a few hrs), and has been trimmed religiously every month. And yes, the (suspected) cause for the founder has been removed.
I see and am concerned about the separation, too. The argument of the (new) farrier to leave some of the wall standing was that the soles are bruised and abscessed at the moment, and are in no shape to carry the weight either, so he tried to level the walls with the soles to leave some distribution of the weight, at least until the abscesses have blown. The boots have a frog support, too. He wants to take the walls further back with successive trims. Clinically - for what it's worth - he is right. The attempt of the first guy seems to have been "take the walls and toe way back" and has resulted in ~4 weeks of excruciating pain, inability to walk, and massive abscesses on both feet.
Honestly, I am at a bit of a loss (again, sigh). There is one lady here who specializes in "natural hoofcare", and honestly, she seems like a complete quack (both from my own and other people's experience well before this laminitic episode). She is the only one around here to do casting, too. I don't want her working on my horse, and I don't want to start self-experiments with casting, so that's not an option right now.
Both farriers who have worked on him thus far came with credentials and good reviews.
Oh well, I guess it's time for someone new again...
