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?
Always consult your vet before giving your pup any medications or supplements.
Article Overview
What Are Probiotics?
Probiotics are formulas containing 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 being disrupted by illness, infection, antibiotic treatment, or other stressors.
Benefits
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
Expert Tip
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 humans. So, it may be best to ease into the treatment with less than the recommended dose, allowing time for your pet’s tummy to calibrate to this nutritional change.
What To Look For
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 strains, such as Bifidobacterium animalis. The best formulas include several different strains to help multiple aspects of their digestive and immune systems simultaneously.
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 can divide to 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).
However, a higher CFU count is ideal for illnesses and health problems, such as inflammatory bowel disease (IBD), 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.
Prebiotics
You’ll want to look for a probiotic blend that includes a prebiotic. Prebiotics promote probiotic growth, which helps keep harmful bacteria under control in the dog’s gut.
Best Probiotics For Overall Dog Health
We’ve chosen our top picks based on several factors, including the variety of blends, other ingredients, customer feedback, and pricing.
Nom Nom Probiotic Support Review
#1
We chose Nom Nom Probiotic Support as the best dog probiotic for its combination of blends, reasonable price, and overall fantastic customer reviews. Nom Nom, a popular fresh dog food delivery service, has two different probiotic blends for dogs (full spectrum and GI-targeted) and a probiotic for cats. Their blends are formulated by their expert team of veterinary nutritionists and microbiologists. The company also offers a gut health test for dogs and cats that can help you determine if they need a probiotic.
The full-spectrum probiotic formula includes a prebiotic and seven different strains of live bacteria to help maintain normal digestive and immune function and intestinal tract health.
The GI-targeted formula includes Saccharomyces boulardii, which can help treat diarrhea, Clostridium difficile, and inflammatory bowel disease in dogs. S. boulardii is also beneficial if your dog is taking antibiotics. It’s a healthy yeast that’s also considered a probiotic rather than a bacteria, so it won’t be killed by antibiotic use.
Recommended use:
- Mix one level scoop of the powder into food once daily
- Protect from light, high temperatures, and moisture
- Refrigerate for optimal preservation
Probiotics included in Full Spectrum Blend: Inulin (prebiotic), Bifidobacterium animalis, Enterococcus faecium, Lactobacillus acidophilus, L. reuteri, L. fermentum, L. rhamnosus, and Pediococcus acidilactici.
Probiotics included in GI-Targeted Blend: Inulin (prebiotic), Bifidobacterium animalis, Enterococcus faecium, Lactobacillus reuteri, Pediococcus acidilactici, and Saccharomyces boulardii.

Most Beneficial Bacteria Strains For Dogs
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. fermentum, L. rhamnosus, L. salivarius, 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 the immune response. It’s also known to protect the small intestine from pathogens, such as E. coli and Salmonella.2
Frequently Asked Questions
Here are some questions our readers often ask about dog probiotics.
Can Dogs Take Human Probiotics?
Human probiotics aren’t harmful to dogs, but they may not help your pup. Why? Many of the bacteria strains in humans can differ from those in dogs, so it’s more beneficial to give your pup a dog-specific probiotic. But keep in mind that a human probiotic blend could have other ingredients that may be harmful to dogs — so it’s wise to go with a doggy blend.
Can Puppies Take Probiotics?
Yes, puppies can take probiotics formulated for dogs. What’s the best probiotic for puppies? Any of the products we review here are safe and beneficial for puppies. Just make sure to follow the recommended serving size for your puppy’s weight.
Are There Natural Probiotics For Dogs?
A good source of natural probiotics for dogs is yogurt or kefir. You’ll want a product that’s high in live cultures with no added sugar or artificial sweeteners. Added sugars aren’t healthy for dogs, and some artificial sweeteners, like xylitol, are toxic for dogs. Also, plain, Greek-style yogurt is better because it has lower levels of lactose, which can cause digestive issues in some dogs.
Fermented vegetables can also be a good source of natural probiotics for dogs, but you want to make sure they don’t contain any onions, garlic, or chives as these are toxic for dogs. See which foods are and aren’t safe for dogs.
Why Do Vets Recommend Probiotics?
See one family’s story about how their vet-recommended probiotic helped their senior Shih Tzu.
