This supplement is intended to help rebalance and support a healthy microbiome. Specifically, it helps reduce populations of certain bacteria, such as Clostridium and E. coli, that can contribute to health problems when present in large numbers. Prior to using the supplement, we recommend testing your dog’s microbiome with a Gut Health Test.

This supplement is not recommended for dogs who experience constipation.

Seek veterinary help if your dog's diarrhea is accompanied by lethargy, loss of appetite, bloating, apparent abdominal pain, repeated vomiting, large amounts of blood or the ingestion of poison or if the diarrhea lasts more than three weeks even if it varies in intensity from day to day.

This supplement is intended to be used for periods of up to 2 months.

This supplement can be given with any other medications and/or supplements. While we’ve seen many dogs benefit from this supplement, we always recommend checking with your dog’s veterinarian before changing their regimen.

While this supplement is intended specifically for dogs with microbiome-related health issues, in rare cases, it can cause symptoms to worsen. Constipation is the most common side effect. If your dog’s symptoms worsen after beginning this supplement, stop giving the supplement until their condition stabilizes.
