Therapy dogs


I was reading a post last night about a German Shepard that a fellow was going to use as a therapy dog. I know my parents used to take my Black Lab in to visit their mothers and the 'ol girls loved the furry beast. As did many others in the facility. Is there something people need to get through to do this now? Neigbhor girl just got a degree in psychlology and has a sweet lab mix dog. It might work well for many people. Sorry if this a bit disjointed but I've been up all night.
