Premium Quality Probiotics for Dogs
Some pups have sensitive bellies, while others simply need daily gut support. Our probiotic soft chews help bring balance back to your pup’s gut so digestion feels smoother day after day. Each chew delivers 3 billion colony-forming units, giving your dog’s digestive system a steady dose of beneficial microbes.
Inside every chew is a blend of nine carefully selected strains: Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus salivarius, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus brevis, Bifidobacterium bifidum, Streptococcus thermophilus, and Bifidobacterium lactis. Together, these strains work with your dog’s natural good bacteria to help keep the gastrointestinal tract running comfortably.
Pumpkin and sweet potato add gentle fiber that helps keep stool regular, while probiotics support healthy digestion. Our chews are made with natural ingredients in a Non-GMO formula, with no artificial sweeteners or preservatives. Every batch is produced in a GMP-certified facility and undergoes third-party testing. Each container includes 30 soft chews designed for simple daily use.
The Science Behind Probiotics for Dogs and Gut
Your pup’s belly hosts a bustling community of microbes that help keep digestion on track. Inside the digestive tract, healthy gut bacteria work alongside other beneficial microorganisms to break down food and help the body use nutrients more efficiently. When that balance tilts, probiotics for dogs help refill the gut with friendly microbes that push back against harmful bacteria.
That microbial teamwork also affects the immune system, which operates largely within the digestive tract. Balanced bacteria help the body respond normally to everyday challenges. Experts in veterinary medicine continue to study probiotic strains that help support gut balance, especially during diet changes or after antibiotic use. As research grows, pet parents learn more ways to care for their dog’s gut health.

Research Studies on Probiotics for Dogs
Research Studies on Probiotics for Dogs
Science plays a big role in shaping better probiotics for dogs. Researchers continue to study how certain probiotic strains interact with the digestive system and influence everyday canine wellness. Curious what the research shows? Take a look at several peer-reviewed studies that highlight the growing potential of probiotics for dogs.
Study on Probiotics and Immune System Support in Dogs
Study on Probiotics and Immune System Support in Dogs
A 2019 study suggests that certain probiotic strains may strengthen dogs’ immune responses and improve gut bacteria balance. Dogs that received probiotic supplementation showed stronger immune markers and healthier microbial profiles. Their appetite also increased, especially in older pups.
Study on Probiotics for Digestive Health and Diarrhea Recovery in Dogs
Study on Probiotics for Digestive Health and Diarrhea Recovery in Dogs
A randomized clinical study evaluated 148 dogs with diarrhea caused by short-term digestive upset. Dogs that received a probiotic paste recovered faster than those given a placebo. Their symptoms cleared sooner, and fewer pups needed additional treatment. The findings highlight how live cultures may help dogs regain digestive comfort more quickly.
Study on Probiotics for Allergy and Skin Health in Dogs
Study on Probiotics for Allergy and Skin Health in Dogs
Scientists tested a probiotic and nutraceutical blend in 105 dogs dealing with itch linked to canine atopic dermatitis. Many dogs showed visible skin improvement within weeks, while gut testing revealed beneficial changes in bacteria. These results suggest certain probiotic blends may promote skin comfort by improving balance in the gut microbiome.
Study on Probiotics and Healthy Gut Balance in Dogs
Study on Probiotics and Healthy Gut Balance in Dogs
Can a single probiotic strain shift your pup’s gut in a healthier direction? A 2014 study tested Bifidobacterium longum in healthy dogs to find out. Researchers observed higher levels of beneficial microbes and fewer unwanted bacteria. They also noted stronger immune cell activity and beneficial gut acids after supplementation.
Research on Probiotics and Behavioral or Stress-Related Effects in Dogs
Research on Probiotics and Behavioral or Stress-Related Effects in Dogs
A 2025 clinical trial tested whether a probiotic strain could improve behavior in dogs. Over four weeks, dogs receiving the probiotic showed calmer responses during stressful events and settled faster after their owners left. Activity tracking also revealed better sleep patterns and steadier daily routines compared with the placebo group.

Trendy pet supplements come and go, but thoughtful science never goes out of style. At HolistaPet, we build our formulas around veterinary insight and modern nutrition research. We use ingredients that help keep your pup’s digestive tract balanced. Our dog probiotics are designed specifically for canine digestion.

We also keep things honest and transparent. Our formulas undergo veterinary review and independent lab testing to confirm quality and consistency. Carefully selected probiotic strains help encourage microbial balance and everyday comfort. What you get is a supplement crafted to fit smoothly into your dog’s daily wellness routine.
How Many Probiotic Chews Should I Give My Dog?
The right serving depends on your dog’s size. Our chews make starting probiotics simple and consistent. They're designed to help dogs enjoy the many benefits of balanced gut bacteria. Use these general guidelines:
- Less than 20 lbs = 1 chew
- 20–50 lbs = 2 chews
- More than 50 lbs = 3 chews
(or as needed)
Does your pup have ongoing health problems or digestive concerns? Your veterinarian can help tailor the serving to your dog’s needs.
How Often Should Dogs Take Probiotics?
Most dogs can take probiotics once a day as part of their regular wellness routine. Daily supplementation helps keep helpful bacteria active in your pup’s gut, which is key to how probiotics work. Consistency matters. Many dogs benefit most when probiotics are given with meals and used regularly. In some cases, a vet may suggest probiotics during diet changes or digestive trouble to help manage diarrhea and restore balance.
Can Probiotics Help Dogs with Digestive Upset or Diarrhea?
Yes, probiotics may help when your pup’s stomach feels off. These helpful microbes support gut balance and crowd out potential pathogens that can disrupt digestion. Dogs that take our infused treats often experience steadier digestion and firmer stools. Probiotics may also offer benefits beyond digestion, including support for overall wellness. If symptoms continue or worsen, a vet can help rule out health problems such as infections or food sensitivities.
Can Probiotics Support a Dog’s Immune System or Nutrient Absorption?
Yes, probiotics can play a helpful role in your dog’s overall wellness. A balanced gut breaks down nutrients more efficiently, helping your pup get more from their meals. Because much of the immune system is linked to digestion, gut balance may also help support protection against immune system disorders or even urinary tract infections. For many dogs, steady digestive balance supports energy, comfort, and everyday health.
Can Probiotics Be Used With Other Dog Wellness Supplements?
Yes, probiotics can be used alongside other dog wellness supplements. Many pet parents pair them with vitamins, joint formulas, or specialized dog foods to support overall health. Each supplement plays its own role, so they often work well together. That said, every pup is different. Dogs with certain conditions, including inflammatory bowel disease, may need extra guidance. A veterinarian can help you choose the safest combination so your pup can enjoy the same benefits comfortably.
