Thanks! He was even a bit worse yesterday, barely able to put the foot to the ground, but better today and we could even walk a small lap around the arena. It was very dark and there were problems with electricity, so I couldn't see if the abscess had erupted, but I still soaked his hoofs in warm saltwater and gave him painkillers (homeopathic). Also, the horses have moved from their summer pastures to the winter field, which involves eating from the feedbin which has a concrete flooring around it, so there is buildup in all of his legs and he needed walking to reduce soreness. I also now massage his legs. Others who have already spent some years at this facility, say that the first year is always the hardest when the horses come up to the concrete area, but after that the hooves get used to it and it becomes much better.
I have come a long way, to surrender my shadow to the shadow of my horse.
