Gypsy is actually a rescue - you may be able to see that her right hind looks nasty around the pastern. We believe she got it tangled in barbed wire, it's rather disgusting-looking with lots of puffy scar tissue. Although she was in foal, the owner was going to shoot her, because they can't do anything major to her foot while she's got the foal.
Now, Gypsy's coat is shiny and she's in excellent weight. She's alert, friendly, and most importantly she isn't lame. She walks just fine on her injured foot and shows no signs of pain. The worst thing observed is that sometimes it itches. So she was rescued, and when she's had the foal her foot will be properly sorted out. It may never be pretty again, but as she's effectively sound even now and is a beautiful horse, there's no reason to end her life.
