I'm so sorry about your little one. You'll probably learn whether or not it is acute or chronic. They usually go on to live normal lives when fed the proper diet and given their medication regularly as well as exercised properly. You can read this, too:
Rich, fatty foods can be very dangerous to dogs susceptible to attacks of pancreatitis. Often you may not know that your dog is susceptible until he is very sick with his first attack. It is often the smaller, more energetic breeds like miniature or toy poodles, cocker spaniels, miniature schauzers, and other small terrier-type dogs who seem particularly prone. However, any dog may have a problem. It is best to avoid these foods altogether.
turkey skin
bacon, sausages, hot dogs
fruit cake, plum pudding
deep-fried
Signs of pancreatitis generally include an acute onset of vomiting (sometimes with diarrhea) and abdominal pain, which may be evidenced as a hunched posture or "splinting" of the abdomen when picked up. The dog may become very sick quickly and often needs intensive fluid and antibiotic therapy.
