Vital Planet Firm Stool is a powder mixed into a dog's food, combining a 10-strain probiotic blend (1 billion CFU per serving) with organic pumpkin seed extract. Intended for occasional bouts of loose stool, not ongoing digestive issues. If diarrhea persists beyond a day or two, or your dog seems unwell, see a veterinarian rather than relying on this alone — ask our staff if you're unsure.
