I use CBD oil for my two senior dogs, but that is for arthritis, as I have seen the sole study on how it can improve mood for arthritic dogs. To date, there isn't any published research (none that I've seen) that confirms the use of CBD oil for any other condition.
However, I do have experience with SA and I know it is a very serious issue for some dogs. I would forego such a self treatment and seek the help of a professional like Malena Martini, who has a lot of experience with SA. See her website-
