My Cali had her first, and only, pancreatic attack about 2 years ago. The board certified vet put her in low fat dog food and suggested that she stay stay on it for life. Frankly, I fear a repeat of the one episode and don’t want her to go through that again. She is doing well - her yearly labs are perfect, but still they feel strongly she should stay on the prescription dog food — so we do! And all is well
That is my only experience with pancreatitis.
