My vet saw her today. I will definitely be there when he comes back. He gave them both injections. I wrote it down at work. bay...something.
I'm so sorry you are going through this - it's so frustrating, along with frightening. Call his office tomorrow early and ask to speak to him, or to have him call you asap. Find out what he thinks and then make sure he hears from you that you want to be there whenever he treats your horses, unless you yourself tell him differently.
