Skinny Dogs Should Be Checked for EPI

You should have any skinny GSD, Doberman Pinscher, Labrador Retriever, or other breed known to be born with EPI checked to make sure their pancreatic acid is working. EPI is exocrine pancreatic insufficiency, which means they don't manufacture enough pancreatin, hence the food is improperly broken down and doesn't digest, causing diarrhea and weight loss. EPI is not uncommon in certain breeds.
