Hi there XXXXXXXXX,
Welcome to Just Answer! I would like to help you with this question, but need a bit more information in order to better assist you.
So the greenish goop is coming out of the end of the incision?
Is the incision area red, swollen or painful?

XXXXXXXXX,
I have to go offline for a bit, but wanted to leave you with an answer before I go, based on what you have told me so far.
You mentioned that your Golden goes tomorrow to have the staples removed. So, I am going to assume that her surgery was about 10days ago. What I think you might be seeing is a little reaction to the staples. Even though they are sterile when placed, they are foreign material that is puncturing the skin. The body starts to react to them, just as it would to a sliver or other material - and there can be some inflammation right around the staples or sutures themselves.
My guess is that when they remove the staples tomorrow, they will wash the area well, and ask you to wash it a few times daily at home with an antibacterial soap. Usually, this type of inflammation clears up within a few days of removing the staples/sutures.
I hope that helps!
