Ok.. i would go out a buy some keretex hoof hardener and NAF hoof moist. I would apply the hoof hardener to the sole 2 to 3 times a week. I would apply the hoof moist to the hoof wall and coronet band ever day. Thhe hoof hardener help to maintain the molecular structure of the hoof or summit, strengthening it and making it nice and hardy.. Wish it worked on the wall.. then maybe my horse would keep his shoes on for more that 4 weeks.

It is more than likely to do with the lack of shoes - and as some of have commented in the other post - it would be a good idea to talk to your vet about getting some Bute for her. You should then be able to get shoes on her. A sympathetic farrier will not hold her back legs up too long and this will help.
