I don't post here too often, mostly just a browser, but I had to share my story.
We've been having some GI issues with Dacia (day-sha) off and on for quite some time. She is going to be 3 years old in December. She's been on prescription food for 1 to 1 1/2 years now due to excessive bowel movements (4-6 times daily) and diarrhea. Periodically she will have these incidents of diarrhea with blood in the stools. The vet prescribes Metronidazole and within a few days she improves.
Four weeks ago, we had another one of these episodes. After a day or two on medication she became very lethargic and didn't want to move. The cat even pounced on her head and she didn't budge! The vet felt a mass in her stomach. He put her on antibiotics and antacids, continuing the Metronidazole, and performed a barium test. The dog swallows a radioactive dye and then xrays are taken every hour to see how it passes through their digestive tract. The vet noticed a void (or shadow) in the stomach that the barium did not fill. The two possibilites were that it was either a foreign body that she swallowed or a mass. Due to her young age, they felt it was a foreign body.
By the end of the day, she still hadn't passed the barium all the way through her system, so we brought her back the next day for more xrays. This was a Saturday and the barium was through by then. By Monday, when our regular vet was back in the office, she was back to her old self, full of energy, tormenting the cat! The doctor thought she must have passed the foreign object (even though we never saw anything) and we agreed to keep an eye on her.
About a week ago, she had another episode with diarrhea. We just asked the doctor for a prescription without bringing her in since we'd been through this so many times before. After the 5 day cycle of medicine, she wasn't any better. I brought her to the vet on Monday and he felt another mass in her abdomen. This time it was farther down the digestive tract, into the intestines. Again, we thought, 'what did she get into'. I thought I'd taken all procautions to keep things away from her.
This time we decided to do exploratory surgery. The surgery would remove the foreign object and while in there, the vet would take a biopsy to test for Intestional Bowel Disorder, similar to Krohn's disease. He called yesterday after surgery to say they found a massive tumor that is inoperable; it's just too extensive. He said that he was shocked the barium from the previous incident made it through her system based on the intensity of the tumor.
I'm now waiting to find out when I can bring her home from the vet. The biopsy results will be back in another day or two and we'll determine what our options are, if there are any. I'm not optimistic, just hoping for as much time with her as I can get.
