So I am taking care of an older mustang mare. She was adopted to a lady who bought her, got her training done, then stalled her and never worked with her/took her out after she got her. She was stalled for something close to 10 years, so she has a big hay belly, and her back is sunken in like crazy.
I've gotten her to lose some weight, but am not quite sure what to do about the back. I've heard pressing in part of her belly will make her back rise, but I have been unable to find the spot to press. I've also been making her run with her hind legs going under her body to make the back arch up more, in hopes of lifting it.
Any suggestions/other methods of helping to raise her back?
