Hi Rachel…sorry you are going through this with your poor pup. I’m thinking the vets possibly should have went straight to the endoscope because all these tests are so costly. which really is the only way to determine if he suffers from that or IBS. (Inflammatory Bowel Disease is ultimately diagnosed by a biopsy that shows the presence of inflammatory cells.).
While I don’t have dogs that suffer from this disease I do have one that gets diarrhea when I give too much fat in diet. There are forums you can google though to find others with dogs who do have Ibd I’m sure for helpful information. Hope this helps a little.
