hmmmm....I don't know
When TJ was a baby he had issues. These noises would come from him that I thought was a monster in his tummy. He had globs of mucus poops, then the runny stools, and vomit. He was put on the antib Metro (short sp version) but that didn't help him, then we did a restriction diet, a single source protein Duck/Potato flavor. That helped a little. Then we did a blood panel which showed his Folate levels were high. The Vet said IBD - over growth of bacteria in his small intestines. We tried Tylan Powder, which worked for TJ. Finally after a year of the Tylan he was able to resume a normal life
On another note....Has he had a Bile Acid Test done?
