Probiotic Powder Supplement for Dogs
Verified Jun 14, 2026
This is a pumpkin-flavored probiotic powder supplement for adult and senior dogs of all sizes. It uses Bacillus subtilis and Saccharomyces boulardii along with fiber from inulin and flaxseed to support healthy gut bacteria and normal digestion. The powder is designed to be mixed with your dog’s regular wet or dry food as a daily digestive support topper.
Overall, this is a well-formulated probiotic supplement for dogs that combines live microbial strains with fiber sources to support digestive health. The use of Bacillus subtilis DE111 and Saccharomyces boulardii is a positive, as these are stable, well-studied organisms for gut support. It’s a good option for owners looking to add probiotic and fiber support on top of a complete and balanced diet.

KibbleLab Review
Strengths
- Contains two specific, named probiotic organisms (Bacillus subtilis and Saccharomyces boulardii) with clearly stated CFU counts per serving, which is important for effectiveness.
- Includes prebiotic fiber sources (inulin and flaxseed) that can help nourish beneficial gut bacteria and support stool quality.
- Pumpkin powder adds additional fiber, which many dogs tolerate well for digestive regularity.
- Simple, supplement-style ingredient list without common protein allergens like chicken or beef, which may be helpful for dogs with food sensitivities when used alongside an appropriate main diet.
Considerations
- This is a supplement, not a complete and balanced diet, so it should only be used in addition to a nutritionally complete dog food, not as a meal replacement.
- Dogs that are very sensitive to added fiber may need a gradual introduction and careful monitoring for gas or changes in stool when first starting this product.
- While the CFU counts are clearly listed, individual dogs vary; some may need more or less probiotic support than is provided in a standard serving.

Top 5 Ingredients Explained
01
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.
02
Inulin
Inulin is a soluble prebiotic fiber commonly added to pet foods to promote beneficial gut bacteria, improve stool quality, and provide low‑calorie bulk for weight management. It can support digestive health and mineral absorption in dogs and cats but may cause gas, bloating or loose stool if used in excess or introduced too quickly, so amounts should be moderated for sensitive animals.
03
Bacillus Subtilis Fermentation Product
Used as a probiotic or fermentation-derived additive in pet foods, Bacillus subtilis fermentation product supplies stable, spore-forming beneficial bacteria and/or their metabolites (postbiotics) to support healthy gut microbiota, digestion, and immune function in dogs and cats. It is generally considered safe and shelf-stable during processing, but benefits are strain- and dose-dependent and owners should consult their veterinarian—especially for immunocompromised pets or when product labels lack clear strain or live-count information.
04
Pumpkin
Pumpkin is used in pet foods primarily as a fiber-rich carbohydrate and moisture source that can help regulate digestion and firm up loose stools or add bulk for softer stools, and it provides beta-carotene (vitamin A precursor) plus small amounts of vitamins and minerals for dogs and cats. It is safe and beneficial when plain cooked or canned (not spiced or sweetened pie filling), should be fed in moderation as a supplement rather than a primary food, and introduced gradually since large amounts can cause gastrointestinal upset or interfere with absorption of some medications.
05
Silica Aerogel
Silica aerogel is an inert, highly porous form of synthetic silica used in pet food and packaging mainly as an anti-caking agent, moisture absorber, or carrier rather than a source of nutrition, so it provides no caloric or micronutrient value for dogs or cats. It helps keep dry diets and powdered supplements free-flowing and dry, but only food‑grade forms should be used and pets should not ingest desiccant packets or large quantities—accidental ingestion can cause gastrointestinal upset or obstruction and manufacturing dust can pose respiratory concerns.
