Our little dog Pixie is still sick post-op 6 days. Its not uncommon for people, and now I know dogs, to end up with GERD after a major surgery. Usually a bit of gut rest, some proton pump inhibitors...omeprazole, and the GERD slowly heals itself if one can keep things down.
Poor Pixie has a bad case of the GERD. Every meals comes back up no matter the food. She spent the night at the hospital with IV therapy and some IV meds to help her increase stomach motility so that food and fluids move through faster instead of coming back up. We picked her up today but the GERD is still there and we are praying she just gets better.
