Prebiotics are a type of fiber that microbiotics in the gut feed on. Most prebiotics in nature come from plants in the form of plant cellulose. Unfortunately, dogs do not process ingredients that contain plant fiber very well. Prebiotic chitin is very similar to plant cellulose and consumed by microbes in the gut in the same way. But this type of “fiber” comes from animals, most abundantly, from insects. Our organic cricket powder provides plenty of gut-feeding prebiotic chitin that won’t irritate your dog’s system.
