Another one of my horses had white line disease and he had a big crack down the front like Buddy but he had space between the hoof wall and the sole where the white line had begun to rot away. Buddy doesn't have that- the bottom of his hooves look pretty healthy- aside from maybe some thrush because it's so wet around here. But yeah, dry ground seems to be the best thing. Another thing though- someone earlier said something about how putting him in a stall could be just as bad because of the ammonia in the urine. For most horses I don't think that would be a problem but for this horse that would almost be true. I dread putting him is a stall because he gets really anxious and in the morning there is so much urine and manure in there isn't one dry piece of shaving in there. Plus I doubt if he sleeps at all or ever settles down. That's why I'm trying to find other ways to strengthen his hooves. But I guess putting him up would be best.
