c-section prices do vary considerably as you can see from another thread. Certainly this was pricey when compared to my own vets but not so when you consider what others have paid.
I would certainly change vets, dreadful attitude from them IMO. As for not being happy that your friend could not pay in full until the following day, when my girl had a c-section on a sunday afternoon 2 1/2 years ago, before I even mentioned paying, she said to get my bitch and pups home and not to worry about settling up, we could pay the next day.
That is the right attitude I feel.
Personally, I wouldn't have left a bitch in whelp at the vets, not knowing what was going to happen. But once a c-section is decided upon I have gone back home (5 mins in the car) because our vets do not allow you in the theatre during the op so we would only be sat in the waiting room getting increasingly anxious.
