I think you are fine with the current approach. I would keep a bandage off in the house if it is not bleeding just to keep air to it. Don't wrap it in vetwrap; the feet sweat and it does not breathe real well. Toddler tube socks are great for keeping feet clean - I just secure over the wrist or the hock with vetwrap.
