I'm so sorry to hear this, I had a similar situation years ago but it involved 2 torn acl's which also required very expensive surgery. We went to a specialist who financed us for the work and we paid it off over time, is that at all a possibility in Italy? Have you called every last place to find out? Try to do something like that, also the surgery seems a little expensive, have you thought about going to a vet "school" they usually charge less and are just as good in my experience. good luck
