My mare has soft feet and not long ago we took her back shoes off but her hoofs all crumbled! Now we put hoof hardener on her feet. She has white feet you see and ive heard that white feet are like soft. Our farrier said we need to get her shod more often. Do you think we should leave 4 shoes on. But we go on the road. My ponies only got 2 shoes on you see. Anyone got any ideas?
