Sorry this is so long, but I just want to get all the info out there to see if someone here can help me.
Here's some background info on my little Hagrid. He's a 16 pound pomeranian mix, 3 and 1/2 years old. I got him at 5 months. Hagrid started out on Eagle Pack puppy formula, and was later switched (gradually) to Eagle Pack reduced fat, then to Eagle Pack Holistic Select Anchovy/Salmon formula when I noticed the ingredients were much higher quality. My Samantha eats this also. He did just fine on this for about a year. I went on vacation in December and had them boarded, and when I picked them up, Hagrid had bloody diarrhea on his rear end. I took them home, bathed Hagrid, and immediately took him to the vet. They said it was just from stress, and gave me an antibiotic and a probiotic and told me not to worry. He was fine for a while, then the bloody diarrhea came back. It's not exactly diarrhea, but more like bloody mucus, and is bright red. From my research, that sounds like colitis, which of course doesn't tell me a whole lot about what's really going on. So ever since January, he has had these episodes where he will refuse food, possibly vomit, have the bloody mucus diarrhea, and then be fine again for a period of a few weeks. He's been on a barrage of antibiotics and such, and I'd been giving him plain yogurt with his food to help digestion after the antibiotics. But every time, the episodes come back, and then he's fine again for a while. Finally, I got to the point where the vet wanted to do a series of Barium Xrays, but he first suggested that I try Hill's Canine ID prescription food. I know Hill's isn't that great, and I hate that they test on animals, but he said it was really easy to digest and may help if Hagrid has IBS. I switched his food slowly again, and he had an episode during the first week. Then he was fine for a while, and he had another episode just this past weekend. Now he seems fine again. Has anyone else had experience with this? I really don't want to subject him to Barium Xrays, as I think it would be very stressful to him. My vet says he thinks it is either IBS, or a condition that I can't remember the name of where part of the intestine sort of overlaps itself. But if it's that, it would seem to me that he wouldn't act so normal for so much of the time. I'm also wondering if it could be an allergy to something, since he is a paw-licker/chewer. I've been so worried about this, and any help or advice would be so much appreciated. I am really desperate to figure this out- I lost my other dog so young and it would truly break my heart if it happened again. Thanks!
