Overview
A powder probiotic and prebiotic supplement for dogs and cats, delivering 12 bacterial strains and 5 billion CFUs per scoop from a 2.5 ounce jar with 60 scoops included. Marketed for digestive, immune, and skin and coat support, formulated without soy.
The product ships as a jar with a lid and scoop rather than single-serve packets, so dosing depends on level scoops rather than pre-measured sachets. It targets both cats and dogs from one formula rather than species-specific blends.
- 12 probiotic strains, 5 billion CFUs per serving
- 2.5 oz jar with 60 scoops
- Soy free
- For cats and dogs
Who it's for
Suits owners managing loose stool, occasional digestive upset, or looking to add daily gut support to a cat's or dog's existing diet. Not a treatment for diagnosed GI disease without veterinary guidance.
Strengths and trade-offs
Drawn from this product's published specifications.
- Works for both cats and dogs from one jar
- Includes scoop for measured dosing
- Soy free formula
- Requires mixing into food rather than a treat
- No flavor variety listed
Performance notes
Probiotic strain count and CFU levels on the label describe what is added at packaging, not necessarily what survives storage or reaches the gut, so results depend on proper storage and daily use over time rather than a single dose.
