Two days after we stopped giving her the Metronidozale she went from not even being able to hold her head up or focus her eyes when she was carried (I swear, she was REALLY awful a couple of days ago...) to sitting up this morning and squeaking her stuffed toy. :)
Of course, she still has A LONG way to go in terms of recovery since she still gets attacks of vertigo every now and then and she still can't sit up for prolonged periods of time (and she hasn't stood or walked for a month...) but the good news is that she's MUCH better than she was earlier this week!
We have no way of knowing how far she'll progress or whether the progress will continue, but for now, this is enough for us. :)
Thank you all SO MUCH for all your prayers and good thoughts for her!! Sydney's such a strong dog with such a strong spirit... there were times that I'm ashamed to say that I'd given up hope that she'd ever get better. :( I should've learned that I shouldn't give up until Sydney does... My love to all of you!
