Bonnie our 4.5 year old sausage dog has suddenly lost the use of her back legs and cannot walk.  The vets think it is IVDD which sausage dogs are prone to getting.  She will have to have surgery as she is getting worse every day.  We are responsible dog owners and we have insurance for bonnie.  We had a £2500 limit for treatment on our insurance and 5 week ago she developed bladder stones and had a stone taking up 95% of her bladder.  She had to have surgery to remove this as well as be on a drip in the days leading up to the surgery to ensure her kidneys were functioning well enough for the surgery.Please help even just a small amount.
