Digestive Health With Probiotics Chicken Supplement
Verified Jul 26, 2026
A soft chew digestive supplement for adult dogs that combines prebiotics, probiotics, and yeast culture to support gut health. It uses Bacillus subtilis as the probiotic, with fructooligosaccharides as a prebiotic and dried chicken for palatability. This is meant to be given alongside a complete dog food, not as a primary diet.

Strong Choice
This is a well-formulated digestive supplement for adult dogs, offering a clear combination of prebiotic, probiotic, and postbiotic-type yeast components in an easy-to-give soft chew. The use of a defined probiotic strain at a specified CFU level is a plus, and the Greenies brand generally has good quality control. It is a good option for dogs who need extra digestive support but are already on a balanced main diet.

Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Provides a defined probiotic strain, Bacillus subtilis, with a stated CFU amount per chew.
- Includes a prebiotic (fructooligosaccharides) and yeast culture to help support a healthy gut environment.
- Soft chew format with real chicken makes it easier to give even to picky dogs.
- Uses safe, well-established preservatives like citric acid and mixed tocopherols instead of artificial colors or flavors.
Considerations
- This is a supplement only and does not provide complete and balanced nutrition, so it must be fed with a full diet.
- Contains chicken and wheat flour, so it is not suitable for dogs with chicken or wheat allergies.
- Some dogs with very sensitive stomachs may need a gradual introduction to new probiotics to avoid temporary loose stools.
- Calorie content per chew is not listed here, so owners of dogs prone to weight gain should count these as treats in the daily intake.

Top 5 Ingredients Explained
01
Yeast Culture
Yeast culture is a fermented yeast ingredient (commonly Saccharomyces cerevisiae) used in pet foods to provide natural flavors, B vitamins, amino acids and microbial metabolites that can support digestion, gut microbial balance, immune function and overall palatability. It is generally safe for dogs and cats, but animals with known yeast sensitivity or certain immune conditions may require caution and effects can vary depending on whether the product contains live organisms or dried yeast derivatives.
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
Bacillus Subtilis
Bacillus subtilis is a spore-forming probiotic bacterium added to some pet foods and supplements to support healthy gut microbiota, digestion, and stool quality in dogs and cats. It can help with nutrient utilization and immune support, but effects are strain-specific and depend on viability (spores are heat-tolerant); consult your veterinarian before use for animals with weakened immune systems.
04
Canola Oil
Canola oil is used in pet foods as a concentrated fat source and palatability enhancer that supplies energy and essential fatty acids—mainly omega‑6 (linoleic acid) and some omega‑3 (ALA)—and aids absorption of fat‑soluble vitamins. It can support skin and coat condition when balanced with animal fats or supplemental omega‑3s, but is calorie‑dense so must be portioned to avoid weight gain, does not provide species‑specific fats such as arachidonic acid for cats, and must be kept fresh to prevent oxidation.
05
Citric Acid
Citric acid is commonly used in pet foods as a preservative, pH adjuster and mild flavoring agent that helps inhibit microbial growth and chelate metals to slow fat oxidation and preserve color and freshness. It provides no nutritional value for dogs or cats and is generally safe at the low levels used in commercial diets, though concentrated forms or excessive intake can cause gastrointestinal upset or decreased palatability in sensitive animals.
