Pancreatitis

Our 5 year old whippet Fergal has recently recovered from acute pancreatitis, an illness that first showed as lameness, then high temperature, severe weight loss, lassitude and nearly killed him. Thankfully, £2000 later (thank you Animal Friends Insurance) he is back to normal but has to have a low fat diet. We have always fed James Wellbeloved Ocean Fish & Rice but the Vet has put him on Royal Canin Gastro Intestinal Low Fat. This is OK but he poos much more eating this food and is always hungry, exceeding the daily dietary recommendation for his weight (335g) by 100 gs or more plus eating a poached chicken breast a day! It's also not very good at replacing the weight he lost.

Does anyone have any experience of pancreatitis in dogs and a recommendation for a low fat food?

Hope to hear from you.
