I've raised £6000 to pay for Bella to have an operation on both of her elbows

Bella was abandoned in a pet store just before Christmas last year. We realised that she had problems with all four legs and was limping quite badly on them all.
The vet believed it was double elbow and double hip dysplasia and we have had x-rays done to determine the extent of the problem.
Her hips are ok for now and can be managed with medication and by keeping her weight down but she has elbow disease in both elbows. We don’t know to what extent yet as she needs to be referred to a specialist for an arthroscopy on both elbows and then she will need to have whatever treatment they decide after that.
The estimated cost of treatment at this time is £3000 per elbow and none of this is covered by insurance beause it is classed as a pre existing condition.
