Hello everyone, I am new to this site so I hope I am posting in the right area. My one year old female doberman has been having soft stool and diarrhea bouts for 2 months now (yes I have taken her to the vet multiple times and have had a myriad of tests done, nothing.) I have come to the conclusion that her heart worm medication (Triheart plus) is what is possibly causing her diarrhea. She started to get normal-ish stools at the end of the month last month, and literally the day after I gave her her monthly dose of Triheart Plus (her second time taking it) her stools went right back to watery diarrhea. I have been keeping her on a bland diet, and breaking up her meals throughout the day. I have also been giving her pedialyte, and pepto bismol when it gets really bad. I have also given her pumpkin, but I am trying to keep the "newly added things" in her diet to a minimum as to not exacerbate the problem. In the beginning, our vet put her on a dose of metronidozol "just in case" of parasites that didn't show up in the fecal sample. I think that's all the details I have about her..is there anyone who went through this, uses this heart worm medication, or has any advice for me? I am stopping her on this heartworm medication next month and hope that it clears up the problem. She acts completely normal otherwise, healthy appetite, drinks a lot, plays a lot, sleeps a normal amount.
