Question about IBS / Soft Stools

We have a young GWSP who seems to have frequent soft stools. She also eats more than our much larger Rottweiler, but does not gain excess weight. Is this a food issue or is there some type of enzyme that she needs?

 

Answer from Dr. Gaylord Brown:
She may have a pancreatic deficiency and need supplements. She may also have a food allergy. Some tests by your veterinarian should be able to help distinguish the two.
