Just a note for the hydrogen peroxide users out there.........DON"T USE IT ON WOUNDS!!!!!! It acts by lysing (destroying) cells, both good and bad. You will inhibit and slow the healing process and create more inflammation using hydrogen peroxide directly on wounds. The only thing in my opinion I would use it for is to remove blood off the coat as it is great for that, but not on a wound. If you need to clean a wound, a very dilute betadine solution (weak tea color), or a very dilute (very light blue) chlorhexadine solution. Recent studies have shown that the levels of medication required to kill bacteria and cells involved in the healing process are very similar.
Also, a few things people may not think about in their first aid kits that can really help......garbage bags, towels, and a foam knee pad/board. You can use the towels as a compression wrap if needed, or in conjunction with garbage bags to place on the ground and keep mud, dirt, and debris from creating any issues. Garbage bags are a must for clean-up post emergency, and a foam knee pad will save your knees when working on concrete or gravel. Just my 2-cents
