She NEEDS to be on a low fat diet, and I mean mega-low. Dairy fats can be the hardest for your Am staff to cope with. Was their a trigger food that caused the attack? Sometimes a dog can get into a sourse of SUPER high fat goodness that we would typically never let them have which can cause the attack. If this is the case then preventing the trigger or any other like source can prevent future episodes, but if that is not the case, back to the low fat diet. Hopefully the damage wasn't severe enough that she needs to be medicated or supplemented with anything. Your vet should be able to recommend a good diet for you, and it is crucial that you follow the diet to a TEE, this means most treats will be cut from the diet, but it is important to prevent further bouts of pancreatitis to prevent a future attack. Each pancreatitis attack can cause scarring on the pancreas damaging the ability of it to perform properly like the inability to digest food properly or cause diabetes. It is tough, but totally manageable. Good luck!
