Top Pick
This probiotic powder is a targeted supplement for dogs who could use extra digestive support, such as those with occasional soft stools, mild tummy upset, or after antibiotics, under your vet’s guidance. It provides several live probiotic strains along with a prebiotic fiber source to help support beneficial gut bacteria. It’s meant to be used alongside a complete and balanced dog food rather than as a main source of nutrition.

Strengths
- Provides multiple probiotic strains with a clearly stated CFU level per scoop to support gut bacteria balance.
- Includes FOS, a prebiotic fiber, which helps feed and sustain the beneficial bacteria in the intestines.
- Contains pumpkin and ginger, which can help support normal stool consistency and soothe sensitive stomachs.
- Powder form makes it easy to adjust the amount and mix into a wide variety of regular dog foods.
Considerations
- Brewer’s yeast is well tolerated by most dogs, but it may not suit those with yeast sensitivities.
- Natural poultry flavor may be an issue for dogs with chicken or poultry allergies.
- This is a supplement only and must be given with a complete, balanced dog food to meet overall nutrient needs.
- As with any probiotic, individual dogs can respond differently, so changes in stool or comfort should be monitored.

Top 5 Ingredients Explained
01
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
02
FOS
Fructooligosaccharides (FOS) are non-digestible, soluble prebiotic fibers commonly added to pet foods and supplements to feed beneficial gut bacteria and support intestinal health. In dogs and cats they can help improve digestion, stool quality and immune support, but excessive amounts may cause gas or loose stools in sensitive animals so levels should be balanced and introduced gradually.
03
Natural Poultry Flavor
Natural poultry flavor is used in dog and cat foods as a palatability enhancer—an extract or concentrate derived from real poultry that adds aroma and taste without contributing meaningful calories, protein, or other macronutrients. It can improve acceptance in picky eaters or mask less desirable flavors, but offers little nutritional benefit and may contain concentrated protein residues or salts, so pet owners should be cautious if their animal has poultry allergies or sodium-sensitive health issues.
04
Lactobacillus Acidophilus
Lactobacillus acidophilus is a probiotic live bacterial culture commonly added to pet foods and supplements to help maintain a healthy intestinal microbiota, support digestion, and reduce the risk or severity of diarrhea and antibiotic-associated gastrointestinal upset in dogs and cats. It is generally considered safe and can support immune and gut health, but efficacy is strain- and dose-dependent, is not a substitute for veterinary care, and owners should consult their veterinarian—especially for young, elderly, or immunocompromised animals—before use.
05
Bacillus Coagulans
Bacillus coagulans is a spore-forming probiotic commonly added to dog and cat foods and supplements to support digestive health and balance the gut microbiome, with heat-resistant spores that make it more shelf- and processing-stable than many live probiotics. It may help reduce episodes of diarrhea, improve stool quality, and support immune function, but owners should use products with clear CFU labeling, follow dosing guidance, and consult their veterinarian for young, elderly, immunocompromised pets or if the animal is receiving antibiotics.
