As a pet parent, you want the best for your furry friend. From investing in the best harnesses for puppies to doing tons of Googling about common dog behaviors to buying the best dog toothpaste to keep them fresh and healthy, you'll do pretty much anything for your dog. And that includes making sure their digestive health is taken care of. If you've noticed symptoms like diarrhea or loose stools or if they are prone to allergies, obesity, or anxiety, you may want to try one of our vet-recommended best dog probiotics to see if this can help your pup feel better and become healthier.
So what are probiotics for dogs, exactly? The simple answer is that they boost good bacteria in your dog's gut. “Having good bacteria in the digestive tract is a direct correlation to your dog’s immune system and overall health,” says veterinarian Dr. Gary Richter, M.S., D.V.M., C.V.C., C.V.A., the founder of Ultimate Pet Nutrition. In addition to boosting the good bacteria, probiotics discourage the growth of harmful, illness-causing bacteria. “Probiotics help maintain an appropriate balance,” Dr. Richter adds. “They help to keep the immune system healthy which can lower inflammation and pain.”
Dr. Richter, along with veterinarian and writer at Native Pet Dr. Juli Goldstein, D.V.M., gave us all the details on the benefits of probiotics for dogs, which dogs are the best candidates, and which probiotics vets and dog parents swear by.

What to look for in dog probiotics
✔️ The Number of Bacterial Strains Present: Probiotics for dogs are only as beneficial as the number of bacterial strains within them. While many supplements have one or two strains (which Dr. Juli says can be helpful), she recommends opting for those with four or more to achieve optimal gut health.
✔️ Formulas Rich in Fiber: According to Dr. Richter, probiotics are even more effective when paired with prebiotics and digestive fiber. “[It gives the bacteria] something to feed on and replicate, continuing to create healthier bacteria and thus making the probiotic more effective,” he explains.
✔️ Potency Per Serving: Even with multiple strains of probiotics in a supplement, it could lack potency. “Probiotics are measured by CFUs or colony forming units — the optimal daily range for dogs is between 1 billion and 10 billion CFUs per day,” Dr. Juli says, noting to prioritize probiotics for dogs that offer billions of CFUs
✔️ A GMP-Certified Facility: You want your pup’s probiotic supplements to be made in a facility with good manufacturing practices (GMP). “These facilities take steps to ensure that the products are safe, potent, and pure,” Dr. Juli says. “Often this is not included on the label, so a call to the manufacturer may be needed to gather this information.”
FAQ
Which dogs benefit from probiotics? While all dogs can benefit from probiotics, given they can help with everything from digestion and chronic pain to joint issues and a sleek coat, Dr. Richter says that those with stomach issues experience the most noticeable improvement post-probiotic.
Dr. Juli adds to this, noting that she frequently recommends probiotic supplements for any of her patients who are experiencing any type of gastrointestinal distress, especially diarrhea. “But probiotics have numerous benefits for dogs in a variety of situations, especially overall immune health because more than 70 percent of your dog’s immune system is in their gastrointestinal tract,” she adds. “Other situations where I may recommend a probiotic include pets with anxiety, allergies, irritable bowel syndrome, obesity, or other immune disorders.”What are the benefits of probiotics for dogs? As previously mentioned, probiotics boost the healthy bacteria in your dog's gut, which in turn boosts their overall health and prevents gastrointestinal issues, among other common ailments, like joint pain.
