Ok, my horse is barefoot, always as been. I have ridden him for 3 years, but actually bought him 4 months ago. At his old barn, there was no gravel to walk on and he lived alone in a 30+ acre pine forest with somewhat scary electric fencing. He was ridden in a dirt or sand ring. Where I have had him for the last 4 months, there is gravel near the gate where he is fed, and he has to walk about 80 yards of gravel road to get to the barn. He is puchy on it, and even more so if I ride him on it. It seriously concerns me that he acts lame when walked on gravel. He as great feet, good angles, very thick wals. The farrier is impressed with the quality of them. The vet said he was healthy as well. Is this normal?
