Thank you all very much for your replies. The good wishes are lovely and the advise really useful. Izzy seems back to her self today

I will have to do lots of reading up on the jabs. I should have been better prepared having had trouble with my childrens jabs, so quite expert on those. The homeopathic vet sounds very interesting and I will have to look into the titre tests as don't want to have to give her a booster, don't think Izzy or I could cope with the stress!
I will post on the general board soon with some photos of our little Izzy!
Thank you all again
