there is no malpractice insurance with dogs they are considered personal property so all you can do is take them to small claims court. Vets are a business and they have business insurance but not malpractice
Also i was told when i took dex in to hospital right upfront - pancreatitis is a very expensive disease to treat and can be life long so they told me right upfront to think about this and i had to give 2k that night after spending 3k already. They recommended plasma transfusion as he was so severe and the last yorkie they lost so i went more aggressive since he relapsed already and was very sick so i felt that saved his life. Pancreatitis is very tough and if combined with ibd in small intestines it can keep recurring then lead to diabetes or epi so it is very important to get it under control fast or it can lead to those other diseases and a dog that gets it can get it very easily again. Diet is very critical and vets do not know very much about diets at all as they only take one nutrition class in vet school so they rely on hill's,etc and hill's i/d caused my dog to relapse and i called the company and they defended the food yet the specialty hospital said many dogs relapse on that food. I was furious but they would not remove from their recommended list for pancreatitis and it has pork in it which is high in fat. The better foods are purina ha or ultra z/d.
I feel lucky dex has been on track but i am a nervous wreck when anyone is at my house telling them to eat outside or over the table as if they drop something i will freak as anything can set him off per vet.
