Try putting her in a crate. A lot of times these crazy bitches that are non stop chain runners or kennel bouncers just don't have the resources to start the cycle. I would do this, keep her in a crate, work her hard on the mill or Jenny twice a week... Get to where she can blast out 30 minutes... No more than that, keep her in the garage in a crate where she can't burn off all calories, and feed her some raw beef and wheat hermana oil as a part of her daily food.
