Best Dog Probiotics & Digestive Supplements

About Best Dog Probiotics & Digestive Supplements

A dog probiotic adds live cultures, and often a prebiotic fiber, to the gut in hopes of keeping digestion steady after a diet change, a course of antibiotics, or ordinary stomach upset. This category covers every format we found real sales data for: soft chews, powders you sprinkle over food, capsules and tablets, and fast, no-mixing gels or pastes for a dog that will not eat. Some picks below, like Nutramax Proviable, show up in tens of thousands of reviews and tens of thousands of monthly purchases, which tells you a lot of owners keep repurchasing them. Others, like Purina Pro Plan FortiFlora, come from a veterinary-diet line that vets commonly send owners home with. Flavors run from pumpkin and salmon to plain liver, which matters if your dog is picky or has a known food sensitivity. None of this is veterinary advice, and a probiotic is not a treatment for a disease. If your dog has ongoing diarrhea, vomiting, blood in the stool, or looks lethargic, call your vet before trying a supplement. For everyday digestive support, the products below give you a real, data-backed starting point.
