Probiotics for Dogs: Ask Your Vet First

If you're wondering whether your dog needs a probiotic, ask your vet. Tummy upsets have many causes, and your vet can check what's going on and say whether a probiotic would help. Day to day, a steady diet, gradual food changes, measured treats and no scavenging do the most for a settled stomach.

Probiotics, supplements and medicines: see your vet or a pet supply store with trained staff. They can tell you whether your dog needs one and which suits it.

Why It's a Vet Question

Probiotics are sold for many reasons, and products differ a lot in what they contain. An upset stomach can come from a change of food, something your dog found on a walk, stress, parasites or an illness that needs proper care. Your vet can work out which, and a probiotic chosen without that step may just delay the right help.

If your dog is on medicine from the vet, or has a long-term health condition, mention any supplement before you start it.

Everyday Habits for a Settled Stomach

Keep the main food steady. Pick a complete food that suits your dog and stick with it.
Change food gradually, over about a week. See switching dog food without upset.
Count the treats. Rich chews and table scraps upset many stomachs.
Stop the scavenging. A solid "leave it" and a watchful eye on walks save a lot of trouble.
Fresh water, always, in a clean bowl.
Keep parasite prevention up to date with your vet's plan.

When to Call the Vet

Call your vet if your dog has an upset stomach that lasts more than a day, keeps vomiting, seems tired or in pain, won't eat or drink, or if you see blood. Call straight away for a puppy, an older dog or a dog with other health problems, because they can go downhill faster. If you think your dog has eaten something toxic, call your vet or an emergency clinic at once.
