Give her a good 15 or 20 minute foot soak in warm water, preferably with epson salts. After her soak, give her feet a good massage with a dry wash cloth, rubbing down the legs to the tips of her toenails, (with the scales, not against them), and make sure to dry rub the bottoms of her feet too. Might as well oil her legs and feet since she's getting the spa treatment, and it's been known to prevent and even kill mites... For the minute that it takes, it's worth it. Now inspect the underside of her feet and toes carefully, looking for an original wound where the bumblefoot set in or if you're lucky, a scab may have been removed in the dry rub. If there's a scab, pick it off and then squeeze it as if it were a blackhead or cyst. I've read that some cases of bumblefoot can be remedied simply by giving regular foot baths as outlined above, while others require more drastic measures. As always, if you have a willing veterinarian, blah blah blah...
