The gastrointestinal tract of dogs contains a complex and dense population of microbiota, including bacteria, archaea, fungi, protozoa and viruses. Depending on the composition and activity of the bacteria, the microbes can be either beneficial or harmful with many links to health and disease.  
Gut bacteria also play a role in preventing weight gain through the digestion of food and selection and absorption of nutrients, one of the main bacteria that governs digestion in dogs is verrucomicrobia.
Following several years of research into the microbial communities living within the guts of overweight/obese dogs, the PetBiome Prebiotic contains the nutrients and active plant compounds that help select and feed those bacteria relating to leanness and energy.
The active ingredients in the Prebiotic are also beneficial for dogs that may not be overweight but have low numbers of bacteria associated with metabolism as indicated by the PetBiome Report.  
The active components of a plant called cyanotis were used in our trials, the veterinary/academia supervised research allowed us to then calculate an effective safe dose for dogs.
 
Feed as per advised in the PetBiome report to increase the good gut bacteria associated with good metabolism (page 19 Biome4Pets Report) and to help increase low levels of Clostridia (page 13 Biome4Pets Report).
