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 riding in the patient's chart. So, patients who have active infections, those who have Ivy's, those who have open wounds, same thing, they don't visit unless the physician documentation is in the chart. Obviously, we can't go in the operating room, but we do have physicians call and say, you know, I've got a special needs child here and he's terrified about dental surgery. Can you come and help? And the dog will be with the patient and pre op and with him right to the door of the operating suite. And we have found that it really has been helpful in calming patients, in helping them reduce the anxiety that they have about a major surgery procedure that they're going to have.
