Thanks for all the suggestions so far. I bought a tool case that looks a bit like an alum covered guncase that has dividers for the storage. I'll see the vet just before I leave. I'll see if I can convince him to set me up with a syringe of Benedryl. Needle and suture or thread will get in there. One of the things I learned from vets around horses was to not use hydrogen peroxide, alcohol, or other strong anti-bacterial on large wounds that need to be closed back up. The peroxide or other a/b will kill tissue and not facilitate mending growth back together, according a vet that told me this.
