Why is the serving suggestion the same for small and big dogs?Updated 2 months ago

"Probiotics are healthy bacteria that grow in the stomach because of the prebiotic, so if it's a 5lb Yorkie, it will grow as much room as allowed in its small stomach and will grow larger with a 150lb Great Dane being that they have a larger stomach."

The prebiotics stimulate the growth of good bacteria in the gut supplied by the probiotics, and they will not cause overgrowth. The good bacteria, though, inhabit the gut, not the stomach.
