Angel has now been here just over 4 months, and his hooves have changed dramatically. When I first posted photos it was clear how weak his left front hoof was - underrun and at a completely different angle from his right hoof.
Now, in the top photo taken last week, you can see how much stronger the white hoof has become. The whole caudal aspect of the hoof is stronger and as a result not only is it less underrun but Angel is also happy to weightbear on it properly.
You can see in the top photo as well how far down his hoof the last growth rings have moved - these chart the day his shoes came off and its clear that at 5 months he will have grown a complete new hoof capsule.
