She did not recover from her episode, however she did seem to be more aware of her surroundings toward the end. Greta, Cody and Oliver howled all night long while I held Dottie.
This morning she struggled to find her way in the backyard, falling down and just unable to walk. So I wrapped her in a blanket and kept her warm until the vet could put her down.
She did give me long eye contact for awhile this morning-letting me know she was ready to go.
