Hi Florence 19, I received your PM. I'm sorry to hear about Joley's problems. It's hard to see our much loved friends struggling with life as the years go by when once they were active and vibrant youngsters. Years ago, I had an Irish Setter bitch that was put on Vivitonin for TIAs at a similar age to Joley. Holly improved and became stable on the medication for just over a year, by which time she was almost 14 and had begun to have further TIAs despite being on the Vivitonin.
As far as I remember, Vivitonin works by improving cerebral circulation, therefor once they're on it, it shouldn't subsequently be stopped.
I hope Joley has a good response to the treatment and she enjoys her life to the full.
Best wishes, Dawn R.
