I'm so grateful for all of the replies
, especially since I've only posted once on here! Sophia has had two fecal tests done and both came out negative for parasites. About a month or so after we got Sophia she started having diarrhea, but we kept it at bay by giving her canned pumpkin. That worked well for awhile, until it stopped working. The diarrhea eventually went away (2 or 3 months) and then it came back. That's when we started all the vet trips. The only treats we give her are Mother hubbard bones, and we break them into small pieces so each small bone becomes six or so treats. I started the pumpkin again and the diarrhea stopped for a day, but now its back, and I'm just hoping it goes away again. There's no doubt that she seems to be tolerating this food better than her old food. So I'm really leaning towards food intolerance/allergy.
