Maybe I'm just a wimp, but if an injury could be helped to
heal faster with surgery,I would insist on it. If they show any obvious pain, I would ask for pain medicine to ease the pain for
them. Dog's are such stoic creatures anyway & don't show us
many of their pains day to day. I would want to help them any
way medicine can help when they can't help but show it.

I am glad you dog seems better.
