I have had two older dogs which had strokes and made almost full recoveries so you would never have known and lived for another two-three years. Also a couple of friends with 'stroke' dogs which recovered well and continued for several years with no more strokes. However, neither of mine was quite as bad as your girl seems to have suffered and that does sound like a really bad one. However, it is amazing how much recovery they can make with just a little time and some helpful medication. I hope you and Noza are lucky and she can recover sufficient quality of life to enjoy some more time with you. If she does not seem to be in any pain, which they often do not, I would give it a few days and see if there are signs of improvement.
