Encouraging/speeding up healing?

Max had an op on Monday to remove a lump on his leg. There is a lovely, neat 3in wound on his leg. It's stitched from the inside, with disolvable sutures.

He is currently in a buster collar, as he will not leave it alone

Is there anything I can use/give him that will speed up the wounds healing?

I know Comfry is good for healing from the outside, but I don't know about using it internally? It's not good for deep wounds though, only superficial ones. Maybe Google it? good luck with him, I hope it heals fast on its own.

...keep it clean and dont let him lick it... nothing else should be needed

Dog saliva normally helps wounds heal quickly, obviously, he cant lick it because of his stitches. We clean any cuts the dogs get (from running around and play fighting) with warm water with a pinch of salt. Also dont let him get too stressed out - I guess you're just supposed to pamper him for the next few days or until his stitches are out lol

no it does not!!!!! old wives tail... its full of bacteria and can cause horrible infections!
