Natural Balance did that with their Duck and Potato formula before and that is exactly what happened to many dogs, really bad stomach upsets. They had upped the potato and many could not handle it. They have likely changed the formula again. It would be a good idea to find another formula, other companies that are good make Duck and Potato, can't remember which ones off the top of my head.
Yes a formula change can cause severe bowel upsets. I sure wish dog food companies paid way more attention to that fact. |
