Have you thought about having a therapy animal program in your library? Here is contact information for some of the organizations out there.
Note: My own dog Too Tall is registered through Therapy Dogs Inc. as well as R.E.A.D. so I have included information on these organizations in addition to contact info. If others have info on the other groups please feel free to email me at firstname.lastname@example.org and I will add the info.
This is an organization that certifies dog and handler teams from around the country. Contacting the main office by phone or email, they will be able to give you a list of teams in the area.
R.E.A.D. (Reading Education Assistance Dogs) through Intermountain Therapy Animals
This is the official organization that registers animal handler teams as R.E.A.D. This is a therapy animal organization that registers teams in Utah, Montana, and Idaho, but they will register any team from around the United States as a R.E.A.D. team. To become registered as a R.E.A.D. team, one must be registered with a therapy organization, and contact Intermountain Therapy Animals. They then ask you to read a handbook, watch a DVD and there is a written test that the handler takes. Once one passes the test and sends in the application fee they are registered as a R.E.A.D. team.
