You definetly need to follow the advice of JH.....get the vet to write a letter. The other vet needs to know and quite frankly is responsible for the bills incurred. The vet that caused this NEEDS TO KNOW...so that he doesn't try this in the future. Bottom line he clearly did not know what he was doing therfore caused this issue. Now I clearly don't think he meant to hurt the animal...however...taking a guess and "winging it"...not acceptable.
