Formulated by Dr. Karen Becker with three distinct microbial ecosystems that create a resilient, well-adapted, and functional gut flora
+ Most pet probiotics are not truly dog‑specific, often using human strains that are poorly adapted to the canine digestive tract, immune system, bile environment, and body temperature.
+ PRIMITIVE PROBIOTICS™ uses species-aligned, healthy microbes sourced from wild canids, healthy domestic dogs, and soil-based organisms—mirroring how dogs naturally evolved to acquire beneficial bacteria.
+ A three‑ecosystem approach restores microbial diversity, combining ancestral strains, modern canine strains, and resilient soil‑based organisms to create a stable, functional, and adaptable gut microbiome.
+ Clinically studied strains deliver targeted benefits, including improved stool quality, reduced diarrhea and gas, stronger immunity, calmer behavior, allergy relief, and better resilience after antibiotics or stress.
+ The formula is science‑backed, safe, and results‑driven, third‑party tested, free from fillers and prebiotics, suitable for all life stages, and designed specifically for the modern dog’s biological needs.
+ Many microbiome-damaging insults disrupt serotonin production in the gut, making anxiety and behavior problems worse. This is the first veterinary-formulated product that blends LP815, a patented, calming strain, with S. boulardii, the strain recommended for use during antibiotic therapy to reduce microbiome damage.
