Funny you should mention a "peak" . My friend's hooves were turning into pancakes that were wider than high (timely trims!). I've rolled the edges a bit and the hooves are staying together nice. I did take a peek and removed a tiny piece of sole at the seat of corn and the sole was quite thick. I'm not doing any more because she has a farrier.
She was quite upset about the "hole" I left. I told her I needed to see how thick, and I told her it retained dead sole and farrier should remove it. She's still kind of upset. I wrote down things for her to look up on the internet to see what I'm talking about. Never thanked me for removing the chips and some of the flare. Oh well!
I don't like that process b/c if it is too thick you have to think harder.
