My prayers for your sister. Glad to hear there are no devastating injuries showing thus far. I had a bull come after me one time. Luckily I didn't have my guard down because I had just been warned by his owner to be careful of him, I had just enough time to pick up a nearby piece of 2x4 and crack him across the head to stop him, it stopped him , but he just stopped and looked at me like "is that all you got". Scared me into staying away from him after that.
