hi! I've rescued a horse just recently. Not in real life though, in game. A red roan Selle Fraincais called Dawn. She had just given birth and her owner had just sold her. I didn't see that she had less than 50 percent health left. And about a year's worth with no feeding. She died but my friend rescued her and gave me an Pandora's box to revive her, and now she's back, as my new favourite horse.
