Since she hadn't come home with diarrhea from the breeder, I stubbornly decided it probably was not the food and stuck with what she had been weaned on. It did take us a few rounds of meds and some probiotics to get her back on track, though. Her stool samples never showed any parasites or worms but the meds seemed to help each time. Once the meds stopped, the diarrhea returned until her final round with the Tylan. Others, notably Jeff and Hemi who has documented his efforts on here, went through the puppy diarrhea rounds and had to use several courses of antibiotics and food changes before things settled down. Hope that won't be the case for you!
