LOL! You turned right upsidedown for that last pic, didn't you? Its this pic that I noticed the changes and includes the other one as well. Its what is going in his mouth at the other end that I'm worried about. The white line has lost integrity, changed to a darker color and is spreading, spells inflammation. Wondering about the sugar and starch he's eating. When you see changes like this, suspect the diet. The hay won't be doing it, but grass and bagged feeds with high nsc will. These can very well be the beginning signs of laminitis. The dark color and overall spreading are proof of changes in this direction. Torque helps this spreading caused by weakness in the white line and although I can see that the frog is now where it belongs, the breakover distance remains unchanged. I have a feeling that this isn't a barefoot trim, I don't see a bevel. The bevel will push the toe back with every step and shorten that distance. Now look at the toe and and see the divot in the sole. Same torque can do that as well. The long toe creates disorganized material for the extra baggage it is and when he breaks over on it, it pushes back into the hoof. If it bites back far enough, it will bite a furrowed tunnel down the face of P3's nose. Some horses are born with this shape to P3 and the sole mimics it, which means when the toe has arrived, that divot will still be there. It the toe arrives and has been a while with the long toe, the bone will be damaged and the sole will mimic it again. If it hasn't been awhile, then the bone is fine and when the toe has arrived, that divot will disappear. I would be putting a bevel on these hinds just like I would the fronts for the next 3-4 trims to get the toe back, get the torque off the toe and have a hard look at the diet.
I suspect the weather has been pretty wet lately as well. The frog has lost integrity and is splatting into the groove. Some dry time and treating for thrush would help.
Sorry, I didn't mean to burst any bubble, but the laminitis/IR/Cushings road is a very serious one and if I can give you a head's up on it, I'm glad to have helped.
Did the trimmer not mention anything about this to you?
