Best Dog Probiotic Supplements of 2026

"I was amazed by the relief my senior Pug got from her allergies after switching from Apoquel to this probiotic. She no longer gnaws her feet or scratches constantly, and her skin has improved dramatically. Not only did this save us a lot of money, but she also enjoys the taste and has no trouble taking it daily."

"I started giving these to my goldendoodle with a sensitive stomach, and the improvement was noticeable. His digestive issues almost disappeared, even on a lower dose than recommended. I’m so impressed I signed up for a subscription."

"Both of my Beagles had a habit of eating their poop, and nothing worked until we tried this. After a short time, the behavior completely stopped. Even my picky eater loves the taste, which is a huge plus for us."

"I've started giving FortiFlora to my Doberman and have seen a clear improvement in her digestion and overall gut health. Whenever she experiences an upset stomach or stress, this supplement quickly brings her back to normal. I appreciate the individually packaged servings, which make it hassle-free for daily use or travel. While it's a bit of an investment, the results make it absolutely worth it—it’s now a staple in our routine."

"After trying various solutions for my German Shepherd’s itchy, irritated skin and digestive issues, I introduced FortiFlora and saw amazing changes within two weeks. His coat is shinier, he’s more energetic, and his digestion is better than ever. I now sprinkle it on his food every morning, and he seems to love the flavor. This product has worked so well that I’ve put it on subscription—highly effective and highly recommended."

"My vet suggested this for my older beagle-pit mix when she had bad diarrhea, and it made a big difference. Adding FortiFlora to my dogs’ meals has resolved their digestive issues, and it’s so easy to use that they eat it without noticing. Now, my dogs have healthier appetites and improved digestion—I won’t skip this supplement again!"

"When my greyhound struggled with stomach and intestinal issues, my vet recommended this probiotic. Since using it nightly for the past 18 months, she hasn't had any digestive problems. The ingredients work incredibly well, and knowing that my veterinary hospital trusts this brand gives me peace of mind. Plus, it's convenient to order online at a fair price."

"I started giving this to my rescue pup who had chronic reflux and noisy tummy issues. After a year of daily use, his reflux has almost disappeared, and I rarely hear his stomach grumbling anymore. I've tried other probiotics, but none were as effective. I also like that it contains multiple beneficial bacteria strains and is more affordable than some alternatives."

"My senior dog had persistent tummy troubles and loss of appetite. After two weeks on this probiotic, she's stopped vomiting and is eating normally again. She didn't notice it mixed in her food, even though she's usually picky. Her digestive health has improved dramatically, and I'm relieved to have found something that finally works."

"After trying three other brands that caused my dog problems like vomiting, diarrhea, and excessive chewing, I returned to this product. Now my dog has no more digestive issues, scratching, or discomfort. I’m committed to sticking with this product—it truly works wonders for my pet’s health."

"My anxious, highly reactive rescue dog has shown subtle yet consistent improvements in relaxation and stomach health since starting this powder. He sleeps more soundly and handles walks near other dogs with much less stress. I’m convinced this supplement makes a real difference, and I’ll keep giving it to him."

"My senior dog used to wake up at night and follow me constantly, but after starting this supplement, she sleeps through the night and is much calmer without losing her personality. I also appreciate that there were no negative side effects, and her quality of life has improved noticeably."

"I couldn't believe the turnaround after giving this to my chihuahua. After just one dose, her vomiting and shaking stopped, and she was back to her normal self. This product really saved us from another vet visit!"

"I've tried pricier options like Forti Flora, but this works better for my Yorkie at a fraction of the cost. The chewable form makes dosing super easy, and my dog likes the taste. Highly recommend for anyone needing a good probiotic."

"My puppy’s digestive issues and anxiety improved noticeably after starting this. Her coat is shinier and there have been no more bouts of diarrhea. Great value for the results!"

"After just two weeks of using these with my picky Toy Poodles, I noticed a visible improvement in their digestion and less paw licking. My senior dog, who never likes new treats, actually eats these without fuss. The price is fair compared to other brands, and I'm sticking with this product because it genuinely works for my dogs."

"My dog suffered from high yeast, causing constant paw licking and ear irritation. After starting these, those issues cleared up. She loves the taste, and it's made a big difference in her comfort."

"I have two dogs who used to eat their own poop and had horrible gas. Since starting these, they’ve stopped the habit and the gas is much less nasty. The treats have a strong odor, but my dogs are crazy about them, so I’ll keep buying."

"I've found this product to be excellent for balancing my dog's gut health and managing her allergies. The single-serve packets are super convenient, and it's easy to mix into meals. Very effective!"

"My dog absolutely loves this probiotic—I sprinkle it on her wet food and she licks the bowl clean every time. I’ll definitely be buying it again!"

"While I appreciate the idea behind these packets, I personally haven’t seen any real improvement in my dog after using them."

"I noticed a huge improvement in my dog's allergies and itchy ears within just a few days. He stopped biting his feet and scratching, and even his sensitive stomach issues cleared up—his stool is much firmer now. This works better than expensive allergy shots, and I'm very satisfied with the results."

"My Dobermans absolutely love the taste of these chews, and they've really helped prevent yeast infections in their ears. There's way less gas now and less itching, which I appreciate. Great value for the price, and I'm a repeat buyer."

"After adding these chews to my dog's routine, I've seen less scratching and dry skin. My picky eater actually likes them, and I appreciate that they come in a sealed pouch for freshness. The chews are crunchy and don't have a strong smell, which is a plus for me."

"I've been giving my dog these chews and have seen significant improvement in his digestive health. He’s much more comfortable now, with fewer episodes of diarrhea. Plus, he actually enjoys the salmon flavor, which makes it easy to give him his daily supplement. I also noticed less itching and better allergy relief, so it’s a win all around."

"My dog has a sensitive stomach and skin allergies, and these probiotic chews have made a noticeable difference. She’s itching much less, her fur is softer, and there’s been less vomiting after meals. She looks forward to her chews every day. The only downside is the price and the fact one jar doesn’t last long if your dog needs more than one chew daily."

"At first, I didn’t see much change, but by the time we finished the first jar, my dog’s mood was brighter, her digestion improved, and she seemed genuinely happier. She loves the taste, and I love seeing her active and healthy. Giving these chews a second chance really paid off."

"My two dogs both struggled with itchy skin and low energy, and one has seasonal allergies. Since adding these chews, I've seen a huge improvement in their skin, digestion, and energy levels. They love the pumpkin flavor, and it's made them so much happier and more comfortable. Highly recommend for overall wellness."

"I bought these for my little guy who was having diarrhea after a new cat with giardia moved in. Both my picky eater and my foodie cat love these chews, drooling for them before every meal. Within days, their digestion normalized and they've been great since."

"My senior Pomeranian used to have severe reflux and would vomit daily, but after starting these, he stopped puking, no longer eats grass, and can even tolerate new treats. Both my dogs beg for their probiotics every morning. They work, are high quality, and have a natural color."
