If you break this stuff down it becomes a bit simpler and you might be able to find a solution quicker.
Laminitic changes - good to know, nothing can really be done about that.
Coffin bone changes - that could be a problem, we can’t change it, might be something to deal with the horses’ whole life.
Coffin bone close to the ground - that is a problem. We can change that. Get the coffin bone away from the ground.
Hoof capsule torn away from coffin bone - That’s a problem. Could be due to coffin bone changes. We can reduce leverage on the hoof capsule at the toe.
Frog migrating forward - Not good. could be due to laminae attachment problems due to coffin bone changes.
Excessive heel length - not good. easily fixed.
So just from a Farrier stand point you can put the horse in a better situation. Once you get those things out of the way, you can continue to evaluate to see what’s going on. Lot’s of good posts here. You need to get the obvious out of the way so you can zero in on the real issue if it’s not the feet.
