J and I met the vet at the barn last night. A great relief to find that all but the exterior of the wound has healed and is firm. The "blow out" was from the exterior area.
Vet removed the rest of the stitches and assured us all is going to be fine (repeatedly).
Elvis can be turned out again in three days, ridden in five days and will no longer need a leg wrap (which will be for protection only) in ten days.
And the best news?
We can go sorting on April 13th!
