This is the injury. She cut the bottom of her hoof at a very sensitive part called the frog, probably with a piece of glass on the road or a very sharp stone. A friend of ours came and helped us fix her up. Thank you! She is doing MUCH better. She still limps a little if she trots, but by next week I plan on riding again! We had to soak it in the salt, dry it, but antibiotic cream on it, and tape it. I still soak it every day. Luckily, it is already re-growing in some places. Anyway, these pictures are a little late, but you see something of it.
