My horse has been barefoot for over 2 years but was in Michigan and not rode much before this past May when I moved him to Colorado. At first he was very sound in the rather gravely arena and pretty solid over rocks. Within a month however he started acting more tender. He seems to get worse by the week. He looks great on the grass pasture but in the arena he will have at least one "ouchy step" for every time around the ring. On the gravel road and rocky trail it is more like every ten steps. He is turned out 24/7 on a large, wet, grassy pasture (I know this isn't ideal, they just turned the irrigation off this week, but it's my only option right now).
He was on a performance grain because he has had trouble keeping weight up but I have switched to triple crown (a low starch formula).
I recently bought him some boa boots for the trail but haven't had a chance to use them yet, I wanted to continue to ride in the arena barefoot to help circulate blood in his hoof but he seems so sore
His hoof wall appears strong and doesn't crack at all even on rocky trails, but his soles are low and it seems like his hoof wall is separating in spots away from the sole.
Today I might of made a mistake by attempting to put a mustang roll on him (his farrier just does a pasture trim, I've heard this is not very good). He seemed extra tender right after (Oh no!:( ).
Anyway, here are some photos, can anyone tell me if this looks like white line disease? The fist two are from a back hoof (which I think looks good, he seems sore only in his fronts). The next is the side view of a front hoof, then the left front (white line looks wiggly near the top). And then the R front - see the separation near the heal?
