I have no personal experience with anything but Valbazen so I always suggest that, but I've always read that fenbendazole is another good dewormer. How long ago did you give it? I'm assuming you went by a dose you found here? I'm so sorry she's not doing well. I hope you can take comfort in knowing that you have went above and beyond trying to help her get better. Sometimes our efforts pay off and other times they don't. How much weight has she lost? Is she losing a lot quickly? Before you start tubing, make sure she's hydrated properly. You probably know this but I always like to mention it just in case
