It sounds like her core temp is low.. wrapping her will not do it.. wrap her in warmed towels.. her own body heat is gone so there is nothing you can insulate .. don't give her cold water, either..
Good advice sir. I will add that you can situate her in a kennel with a heating pad on low underneath half of it for the night. Cover it with a towel too. Warm oatmeal would be good! With some Karo syrup for energy.
Good luck! TerriO
