Oh, poor baby! How frustrating. There is a ton of great info on irritable bowel and inflammatory bowel on dogaware.com. Check out thei digestive disorders thread. My dogs never lost appetite when battling Giardia or Coccidia. Also never noticed any rumbling. So maybe something different is going on. But, I believe all the antibiotics and dewormers I used gave them a leaky and/or irritable gut. I used several of the supplements suggested on the above mentioned site to repair it and they are doing much better. Check out the website and I hope your get can come up with an answer from the test. Best wishes.
