Why is there no price on this page?
Retail prices change frequently, and publishing a figure that goes out of date is worse than publishing none. Check the current price on the retailer's page.
Who is this product not suitable for?
A supplement, not a medicine — it does not diagnose, treat or cure any condition. Persistent or severe diarrhea needs veterinary assessment rather than a supplement. Sachet format costs more per dose than bulk powders. Response varies between individual dogs.
Can this replace veterinary treatment?
No. It is a supplement marketed to support digestive health, not a treatment for any condition. Persistent or severe symptoms need veterinary assessment.
