I'm sorry to hear that your girl is having this issue. Nails becoming soft as you have described can be from several things. Some of the more common culprits include thryoid issues, Cushings, immune system issues (like Lupus) and nutritional problems. It would be advisable to have her into your vet so that this can be pinpointed.
