And of course, we have our own medical centre policies and procedures for therapy dogs in the facility and so we want to make sure they're following those procedures and then they're compliant with our programme manual that we provide for them so that we have the standardised programme. So where do the dogs visit? Just about everywhere. Throughout the facility, except, patients who are on contact precautions or in a sterile environment. Unless, physician approval is documented, and occasionally we do have physicians who say, you know, the benefits far outweigh the risk for this patient, I want the dog visit. But when that occurs, of course we need that in writing the patients chart. So, patients who have active infections, those who have IV's, those who have open wounds, same thing, they don't visit unless the physician documentation is in the chart.
