Mliponoga, thanks for your input. I love her owners like family, so I'm reluctant to be bashing how they care for their animals... But I also consider Belle a rescue. She needs better care. I intend on (gradually) switching her to an alfalfa grass mix once I get her moved, which should help with her weight, but what do you think would also help? I heard dumping about a half cup of vegetable oil into some grain and feeding it to her would do wonders, but I haven't talked to anybody who has tried that.
