Nina...
After over an hour, I still can't get that report to post here.
SO... do this... search "A retrospective study regarding the treatment of lupoid onychodystrophy"
You're looking for the study by the American Animal Hopspital Association and it's a 12 page pdf that studies 30 dogs.
That's as close as I can get you to the study short of coming to your house and physically handing it to you.
Let me know if you find it.
