Sorry if this is gross, so stop reading if you don't want to hear about poops. My puppy (Bruce Wayne) has been having loose stools and sometimes just flat out runny poops. I was feeding him Blue Buffalo chicken and rice, and switched him to Taste of the Wild high prairie, seems to be helping but sometimes he still has a soft poop. My vet has ran two of his stool samples and says that there is nothing in his sample. Anyone have any suggestions?
