I have decided that until I can change my current situation with my horses I will be at the barn every evening to feed and water my girls myself.
I got a much better look at Rosie tonight and laid my hands on every inch of her. She is lacking in muscle tone, but she feels to have a bit of fat between skin and ribs. I'm not liking her hips, but I can't feel the points still plenty of padding. Her coat is very dull and lacking in luster. I'll get oil back into her diet now and ask my vet about weight gain supplements. I don't think an "emergency" visit is needed so I've added Rosie and Bonnie to her list when she comes to the barn again in two weeks.
The outdoor arena was not sloppy but wet enough to be annoying. I worked with Bonnie in it anyway. Too nice of an evening to go indoors. I stuck with sensitizing and desensitizing and giving to pressure. She pushed her limits with me a couple of times, half rearing instead of backing because there was standing water behind us. So I kept the pressure up until all four hooves were firmly in the water. Then she could stop and rest!
I finished with a walking ride around the arena, serpentines, easy roll backs, and leg yields. Got to REALLY use that one rein stop when three horse eating geese landed right beside the fence. Hooves and mud flew everywhere. She stayed up right some how now sure how and I stayed in the saddle so all was good!
