Should I message my ex‑coworker to confront her about her dog?

I used to work with an old bitch who was obsessed with dogs and thought they rule the world. I had one of her dogs jump on me and nearly rip my jumper. I told her I didn't like her dog and she threw a tantrum at me.

I nearly slapped her. I couldn't say much or they would kick me out as she was friends with the director.

I really want to message her and tell her she is a bitch and how disgusting she and her dogs are, and that I will sue her for her dogs.
