Human probiotics have become a health craze due to their numerous benefits, but have you considered them for your furry friend?
We all know how fickle a dog’s digestive system can be. Fortunately, specially formulated dog probiotics can be a life-changer for dogs suffering from digestive and other health problems. What do you need to know about pup probiotics, and which products are your best bets?
Note: Always consult your vet before giving your pup any medications or supplements.
Probiotics are formulas that contain living gut-friendly bacteria found naturally in the digestive tract and other areas of the body. The goal of ingesting probiotics is to maintain healthy levels of good bacteria, prevent gastrointestinal (GI) problems and boost the immune system after it’s been disrupted by illness, infection, antibiotic treatment or other stressors.
Probiotics have many health benefits, but some key advantages include:
- Decreases incidences of diarrhea and flatulence
- Improves bad breath
- Helps recovery from illnesses and infections
- Enhances immune response
- Helps manage many diseases, like inflammatory bowel syndrome and kidney disease
- Reduces pain and swelling due to anti-inflammatory properties
- Improves stress response
Many report diarrhea or other stomach upset upon starting a new probiotic regimen. However, this is common with any major dietary adjustment — for pets and for humans. So, it may be best to ease into the treatment with less that the recommended dose, allowing time for your pet’s tummy to calibrate to this nutritional change.
Each dog’s health needs are different, so you want to look for a probiotic formula that contains bacterial strains that address those individual needs, e.g., intestinal infections, diarrhea, etc. For that reason, we’ve listed the probiotic blends included in each product we review.
Products you’re considering should list the specific bacterial species and strain, such as Bifidobacterium animalis. The best formulas include several different strains to help multiple aspects of their digestive and immune systems at the same time.
We’ve included a summary of the best bacterial strains for dogs and their specific benefits. Click here to jump to that section.
What Is CFU?
When comparing probiotic formulas, you’ll usually notice a CFU count as a prominent “selling point.” CFU stands for “colony-forming unit,” and a CFU count quantifies how many live bacteria cultures in a probiotic are active and able to divide and form these beneficial colonies.
Is a higher CFU count better? It depends. If you’re giving your dog probiotics daily to maintain digestive and immune health, a lower CFU count should suffice (between 3-10 billion CFU).
A higher CFU count, however, is ideal for illnesses and health problems, such as inflammatory bowel disease, food allergies, after antibiotic treatment and other cases. Studies suggest you can also give healthy dogs probiotics with high counts — it’s not believed to be harmful.
You’ll want to look for a probiotic blend that includes a prebiotic. Prebiotics promote the growth of probiotics, which help keep bad bacteria under control in the dog’s gut.
We’ve chosen our top picks based on several factors, including the variety of blends, other ingredients, customer feedback and pricing.
We chose Nusentia Probiotic Miracle as the best dog probiotic for its combination of blends, reasonable price and overall fantastic customer reviews. It even has a 60-day 100% money back guarantee.
This formula contains 6 different strains and a prebiotic to combat dog diarrhea, loose stool, yeast overgrowth, bad breath, constipation, itching & scratching, allergies, digestive issues and gut-related problems.
Recommended use: Sprinkle a small scoop of this tasteless and odorless powder on your dog’s food. You can store it at room temperature for up to a year.
Blend includes: Inulin (prebiotic), Bifidobacterium animalis lactis, Lactobacillus acidophilus, L. rhamnosus, L. saluvarius, L. plantaram and L. reuteri.
NomNomNow, a popular fresh dog food delivery service, has a high-quality probiotic blend formulated by its expert team of veterinary nutritionists and microbiologists. The company also offers a gut health test for dogs that can help you determine if your dog needs a probiotic.
This probiotic formula includes a prebiotic and 7 different strains of live bacteria to help maintain normal digestive and immune function and the health of a dog’s intestinal tract.
NomNomNow’s probiotic didn’t take our top spot because it’s relatively new and we haven’t found enough customer reviews to recommend it as our #1 pick. And at $45 for a month’s supply, it’s pricier than many other probiotics for dogs. But, it is worth considering for its strong nutritional formula.
Recommended use: Mix one level scoop of the powder into food once daily. Protect from light, high temperatures and moisture. Refrigerate for optimal preservation.
Blend includes: Inulin (prebiotic), Bifidobacterium animalis, Enterococcus faecium, Lactobacillus acidophilus, L. reuteri, L. fermentum, L. rhamnosus and Pediococcus acidilactici.
- $45 for a 30-day supply

This product contains 100 million CFU per gram of Enterococcus faecium and other beneficial ingredients, such as vitamins E, B and C, antioxidants, beta-carotene and zinc.
Bacterial species used most frequently in probiotics for dogs are Bifidobacterium and Lactobacillus.
Bifidobacterium animalis is found in your dog’s large intestine. It helps to improve overall intestinal health, prevent inflammatory activity and infection and resolve canine diarrhea.1
Enterococcus faecium aids in digestion and helps to maintain a healthy mix of bacteria in the dog’s stomach. It also supports inhibitory effects against shigella, E. coli, salmonella and other pathogens.1
Lactobacillus acidophilus helps to promote antibacterial and antifungal properties in the GI tract. It also helps prevent diarrhea associated with an antibiotic. Finally, it may help reduce cholesterol levels and improve weight gain/growth in puppies and younger dogs.1
L. fermantum, L. rhamnosus, L. saluvarius, L. reuteri, L. plantarum and L. casei all figure prominently in populations of normal canine microbiota. Along with providing strong anti-microbial activity in the GI tract, these bacteria are also extraordinarily vigorous and capable of significantly modifying and improving inferior intestinal health.1
Pediococcus acidilactici is used to treat constipation and diarrhea, relieve stress and enhance immune response. It’s also known to protect the small intestine from pathogens, such as E. coli and Salmonella.2
