I noticed you first posted about your frog Slurp having problems back in july and that her brother died from redleg. Also that you were suspecting her to have MBD and said her legs where pink and that you thought she had maybe got the redleg. If this is correct I highly doubt its redleg because in that amount of time if it hasn't cleared up yet your frog would have passed by now or would be almost near death and from that picture of her IMO she doesn't look ill with red leg to me. I could be wrong because I don't own any whites but I know about red leg. Was the one that died of red leg diagnosed by a vet? You need to post a pic of her belly and thighs. Also does she have any open sores? if so you could put some Neosporin without pain reliever on the open sores to help with healing. But again im really starting to wonder if this is whats wrong.
