In this picture you can see the lack of connection between the sole at the toe and the hoof wall itself.
The toe shows some built up sole that I *could* remove. There is a very good chance that would make him sore, but it would also allow me to remove a bit more wall and take the lever forces off his toe, which would make him more comfortable and encourage better growth at the top. Instead I aggressively rolled the wall, and I'll check it again in a week. That's the beauty of having him at home, I can do that.
Had he not been with me, I would have likely removed it, trimmed the wall, and cast him again. That would have giving him the support and protection to keep him comfortable, while setting him up for good hoof form for 4-6 weeks.
But since he's with me, I can tweak my trim every week or two and do more good in a shorter period of time. He likes his heels low, and that toe rolled. Right now he is trotting around the pasture, chasing Honey barefoot. Him feeling good is more important then having that *slightly* better looking foot. Especially since as soon as he is ready to loose that 'pad' of sole, I can remove it the same day.
Here is that picture mapped. The green line is the end of his sole, and the blue line is the hoof wall. There should be no gap between these lines, as you can see the closer to the heels you go the closer they get together. That there is a gap means the hoof wall has disconnected from the internal structures of the foot. The next picture shows the angle change this makes. As the new angle reaches the ground the blue/green lines will get closer and closer together.
At this point she couldn't stand for more then about 10 minutes. But 'angle' wise she wasn't bad.
I trimmed Honey while she laid in the pasture over a course for 2-3 days. She responded very well, very quickly to having those heels removed. In one trim she went from laying down all day, to standing most the day. In 4 weeks she was walking and standing all day, in 8 she was trotting in the pasture. This is the same foot about 8 weeks after I got her. You can see the extreme angle change at the top of her hoof. Today I would probably take a straight cut and take the end of that toe off, but this was from a couple years ago.
