Overview
PetLab Co.'s dog probiotic is a pork-flavored soft chew formulated for small dogs, built on a blend of spore-forming probiotic strains (Bacillus coagulans, clausii and subtilis) plus prebiotic fibers and a postbiotic yeast blend. The 30 count bag targets gut health, occasional diarrhea, digestive upset, paw licking and seasonal allergy support.
Spore-forming probiotic strains are chosen in supplements specifically because they survive stomach acid better than many standard strains, which matters for a chew that has to make it through digestion intact to reach the gut. The formula pairs those live strains with FOS and GOS prebiotic fibers meant to feed them once they arrive.
- 30 soft chews
- Three-strain spore-forming probiotic blend
- FOS and GOS prebiotic fibers
- Formulated for small dogs
Who it's for
Owners of small dogs dealing with occasional loose stool, digestive sensitivity, or paw licking linked to seasonal allergies who want a daily gut-health chew. The pork flavor and small-dog sizing make it less relevant for owners of larger breeds needing a bigger per-chew dose.
Strengths and trade-offs
Drawn from this product's published specifications.
- Spore-forming strains built to survive digestion
- Combines probiotic, prebiotic and postbiotic ingredients
- Targets both digestive upset and allergy-linked paw licking
- Dosed and sized specifically for small dogs
- Pork flavor and allergen listed, a concern for dogs with pork sensitivities
Performance notes
The listed strains are spore-forming, a trait that helps them survive the trip through stomach acid rather than breaking down before reaching the intestines, while the added FOS and GOS prebiotic fibers are meant to support those bacteria once established. The postbiotic yeast blend (Saccharomyces cerevisiae, Cyberlindnera jadinii) supplements the live strains rather than replacing them.
