Inside your dog’s digestive tract (and yours), is something called a microbiome. The microbiome is a colony of bacteria that live throughout your dog’s body. But the largest – and most important – colony lives in your dog’s intestines and gut.
The micro-biome might not seem like a big deal, but it’s a vital part of your dog’s body. In fact, those bacteria outnumber your dog’s own cells by 10 to 1. And there are 100 trillion of these organisms in the gut alone.
