Sciam reports that "many animals, including man's best friend, also suffer from both short-lived and chronic digestive woes. As a result, some veterinarians have begun prescribing supplements containing friendly bacteria, or "probiotics," to ease related symptoms such as diarrhea, vomiting, gas and bloating. But some animal experts say there is little solid evidence that the supplements are effective."

I wonder how much research has really gone into this or is this just a new way to market to pet owners? Thoughts?
