Hi. I'm so happy to have found this sight in the middle of the night after being up with my girl who is in CRF and has a terrible problem with diarrhea and loose stools. I will attempt to give you as much of her history as I have. She is a 12 year old rescue, terrier mix. She has always had a very acidic stomach, upset stomach until the last couple years it seems to have gotten better. We always fed her Purina One kibbles. I wish I knew then what I know now about grain free food and homemade food. Back in April of last year for her regular visit the vet said her BUN and creatinine were a bit elevated. She suggested a grain free kibble and Standard Process Canine Renal Support and Canine Whole Body Support on her food. In November she became lethargic, was drinking a lot and had diarrhea. Back to the vet and her BUN and creatinine were about 3 or 4 times above normal. Vet suggested a homemade diet but to only include chicken or turkey, pumpkin or sweet potato, a couple tablespoons of dark greens and the supplements mentioned above. We started Sub Q fluids(Lactated Ringer injection) and started them at home 3 or 4 times a week initially. Immediately we saw improvement from the fluids I believe. She continued to eat but had diarrhea. After a couple of weeks and trying a couple different things....an antibiotic which made her very sick, cordyceps for a couple weeks, olive leaf....none of this seemed to help with the diarrhea. We found a product called DiarRice which is used to treat diarrhea and soothe their digestive tract. It contains rice flour, dried pumpkin meal, flax meal, sodium bentonite, chicken liver hydrolysate, fructooligosaccharide, fruit pectin, and 5 different probiotics. It helped with the diarrhea which I know is not curing her problem, just masking it. We took her off the DiarRice and 9 days later the diarrhea was back. Put her back on the DiarRice and it seems to help for the most part. Some days she has firm stools while other days mushy. It has masked the watery diarrhea. The vet then wanted me to add some new things to her diet to try and get it balanced. We then did 2/3 cup of protein, 1/3 organ meat, 1/3 cup vegetable, dark greens, 1/2 teaspoon seaweed calcium, fish oil (we were doing an omega-3 supplement to start), Standard Process canine renal support and Canine whole body support., and the DiarRice. The next day she had horrible, watery diarrhea. In my opinion, it was either the organ meats or the calcium. I put her back to just the very basic diet. That seemed to help if I included the DiarRice. My questions are....even though a very basic diet is not nutritionally sound, considering her issues, is it just better to get them to eat something rather than worry about all the supplements? Is there anything else that people have tried for diarrhea? I did add a little white rice the last few days and that doesn't seem to make it better or worse. We continue to give her Sub Q fluids 2 or 3 times weekly at home. I will have to get the results of her blood work and post them, but we had her blood work done a couple weeks ago and her creatinine and BUN were a little lower and her overall kidney function was the same. I asked about phosphorus and the vet said that hers was normal right now. She said her blood pressure was a bit elevated but didn't want to do anything with that right now. She is not losing weight and she continues to eat pretty good. Thank you for taking the time to read this and if anyone has suggestions on controlling the diarrhea I'd appreciate it.
