Some breeds of dog are more susceptible to this condition than others and it is one that should be treated in consultation with your veterinary surgeon. However, there are certain foods which are helpful in compensating for the maldigestion and diarrhoea that occurs. Tree Barks Powder is a herbal mixture of Slippery Elm and Poplar Barks that we have developed for this particular nutritional purpose. It is used for the reduction of acute intestinal absorptive disorders and to compensate for maldigestion due to its highly digestible ingredients and a low level of fat. Adding this to each feed has proved to be very helpful for animals with this condition as it is effective in soothing the digestive system, helping recovery from the diarrhea that results and can be safely given indefinitely, if required, in cases of chronic exocrine pancreatic insufficiency.
