Peanut-
Here's a weird idea that might help you leave your incision alone. (My human has done variations of this with 3 dogs, so bear with me!) Ask your human to sew a sock to the end of the sleeve of a t-shirt. Then put the t-shirt on, with your leg through the sleeve and into the sock. (the other leg just goes through the other sleeve, no sock) Snug up the waist of the shirt with a knot tied to take up the slack.
Ok, the shirt will be on "upside down and backwards" and you will lose street cred with the other dogs in the neighborhood (cuz it's just not the same as wearing a baseball cap backwards) but it might work.
Just be careful if you have slippery floors. It might not be such a good idea in that case. Might need to have your human get creative with the sock end so you can grip the floor a bit.
