German Shepherd Dogs are predisposed to a disease called Exocrine Pancreatic Insufficiency (EPI) which causes chronic diarrhea and weight loss due to maldigestion. This disease is fairly simple to diagnose and treat. Here is a link with more information on this disease: https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1627

    Great question! You will not always see worms in the stool. Usually we only see microscopic eggs. I recommend taking ZigZag to the vet with a fresh stool sample so they can look for those eggs. Not all over the counter dewormers treat all intestinal parasites so you really need to find out what one(S) she has so she can get the proper treatment. Good luck and kisses to ZigZag!
