Thanks RockinD! You know, in the 6 or 8 weeks since I took that picture, we've been on a "fitness" plan - one or two days of hills, arena work a few days, nothing too hard, just breaking a little sweat (like how I would work out!) to try to condition and build some muscle. Her butt is definitely improving, and she's getting a nice layer over her ribs, but the top line, you're right...it's a LITTLE bit better, but it's going to take time. She really wasn't ridden much in the two years before I got her so I'm hoping "nutrition and exercise" will work in time. I also got an orthopedic saddle blanket that adds some padding in her withers and takes pressure off her spine so that at least she's more comfortable (I hope). Thanks for the tip, I'll look into the coconut oil!
