Episode notes
Rescue Dog Led To FMT Breakthrough
- Holly Ganz told how her rescue herding dog developed hemorrhagic gastroenteritis and required hospitalization until the gut microbiome was restored.
- She used an oral fecal transplant capsule to rebuild the dog's gut and solved the chronic GI crashes that had lasted over a year.

- The gut microbiome acts like an organ, encoding far more digestive enzymes than the host.
- It shapes immunity, bile acid processing, neurotransmitters and connects to skin and brain health.
Treat Prolonged Soft Stool Early
- If a puppy's stool stays soft several weeks after weaning, consider support like Saccharomyces boulardii.
- Start with small doses and reduce if stool firms too much.
