Digestive Health With Probiotics Chicken Flavor Soft Chews Supplement
Verified May 26, 2026
A soft chew digestive supplement for adult dogs that combines a probiotic (Bacillus subtilis), a prebiotic fiber source, and other supportive ingredients in a chicken-flavored base. It’s designed to be given alongside a regular complete diet to help support everyday digestive function and stool quality. The chew format makes it easy to give as part of a daily routine, especially for dogs who enjoy treat-like supplements.
This is a well-formulated daily digestive supplement for adult dogs that provides a meaningful amount of probiotics alongside prebiotic support in a highly palatable soft chew. It’s best suited for dogs who need mild, ongoing support for normal digestion rather than those with severe gastrointestinal disease. As with any supplement, it should be used in addition to, not instead of, a complete and balanced dog food.

At a Glance
KibbleLab Review
Strengths
- Contains a defined probiotic strain (Bacillus subtilis) in a substantial colony-forming unit (CFU) amount to help support the gut microbiome.
- Includes FOS (fructooligosaccharides), a prebiotic fiber that helps feed beneficial gut bacteria and works synergistically with the probiotic.
- Soft chew format with real dried chicken and glycerin is typically very palatable, which makes daily dosing easier for most dogs.
- Simple, straightforward ingredient list without artificial colors and only commonly used, safe preservatives (citric acid, mixed tocopherols, rosemary extract).
Considerations
- This is a supplement, not a complete and balanced diet, so it must be fed along with a regular dog food that meets all nutritional requirements.
- Contains wheat flour and chicken, which may be problematic for dogs with known wheat or chicken allergies or sensitivities.
- Canola oil and glycerin add some calories; in small dogs or those prone to weight gain, these extra calories should be factored into the overall daily intake.
- Not appropriate for puppies or growing dogs unless specifically directed by a veterinarian, as it’s formulated for adults.

Top 5 Ingredients Explained
01
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.
02
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.
03
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
04
Vegetable Glycerin
Vegetable glycerin is a plant-derived humectant and sweet-tasting solvent commonly used in pet foods and treats to retain moisture, improve texture, dissolve flavorings or vitamins, and enhance palatability. It provides usable calories, is generally regarded as safe for dogs and cats in typical amounts, but excessive intake can cause digestive upset and may be a consideration for diabetic pets or those needing calorie-restricted diets.
05
Lecithin
Lecithin is commonly used in pet foods as an emulsifier and texture stabilizer—typically derived from soy, sunflower, or egg—and supplies phospholipids (such as phosphatidylcholine) that help disperse fats and maintain product consistency. In small amounts it contributes choline and supports fat digestion and cell membrane health, but it is not a primary nutrient source; soy-derived lecithin may be a consideration for pets with soy sensitivities and very high intakes can occasionally cause mild gastrointestinal upset.
