Bump on dog's eye

[HailVictory88]

My dog, who is fairly old but in mostly good health, has had a small bump on his eye for a while. Recently, it has been irritating the eye and causing a lot of discharge. We've tried treating the discharge, but the vet said that as long as the bump is there it will be a problem, and that a minimally invasive surgery to remove the bump has a good chance of working.

Does anyone have any information on how to make sure my dog handles this well, or any astrological information on timing the surgery? (I'm not sure how flexible I can be with time and I don't want to wait too long). I think it should work out but wanted to maximize the chances of it going well. I figured avoiding Moon in Aries is essential. Thanks!
