I haven't had one of mine cut a pad that deeply. With the stitches being out. I would be tempted to do Epsom salt soaks. They keep the scab a little softer, where possibly it wouldn't break open when walking. While you want things to be able to air-dry. I think I would sock the foot, to give extra cushion when walking him outside. I wouldn't leave a sock on him, without having non-stick gauze covering the wound. Because if it bled, and dried. The scab would stick to the sock.
I'm a big fan of vetericyn, for getting things to heal.
Years ago we used Cut and Heal, on dogs, and horses. It worked great, getting wounds to heal in hard to heal places. I haven't used it in many years. What I remember about it, was it was messy, had an overwhelming strong smell. Also a good chance it will stain carpet. You can Not bandage the wound, when treated with it.
You might consider doing a little research on it. If nothing else works.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
