Medstar Union Memorial Hospital in Baltimore recently added a K-9 unit to its security team, according to an article and video on the WBALTV website.
The two German shepherds and their handlers spend their days roaming the halls of the hospital. They aren't drug- or bomb-sniffing dogs, but are trained in patrol and protection.
In just the few months since they began working, officials at the hospital said the dogs' presence has helped to reduce the number of security incidents, especially in the emergency room, where tensions can run high, the article said.
So far, the hospital says the reaction to the dogs has been positive and a good way to interact with patients, staff and visitors.
