Did she have localized mange? If so, that is normally left untreated (or you can treat topically with NEEM and immune boosting supplements) and the immune system will take care of it on its own. It's actually quite common in dogs under the age of 2. Rafi had it twice when he was between 1 and 2.
I agree to wait until she is in perfect health before spaying.
