Evidently, the original dogs are soon to be adopted (May 3 is when they go home!), but Colin has two slightly older beagles in mind for her next therapy dog pair.
I think this is a fabulous opportunity for the shelter and the dogs there. Successful therapy dogs, certified or not, must appear more appealing to adoptive homes. These are dogs with stable temperaments, who are able to be calm and comforting in a strange (to them) environment. This also gets the dogs out of the shelter environment and interacting with people, so they don't end up with kennel syndrome.
This might also inspire people to train and certify with organizations like Pet Partners (which until right this second I thought was still called the Delta Society) and Therapy Dogs International. Some people might not otherwise have thought about therapy dogs and nursing home visits, and might discover a rewarding hobby (should that be called a hobby?) for both themselves and their dogs. Bunny at Tales and Tails makes nursing home visits (maybe Kuster will calm enough to do so as well one day, sidelining from his SAR duties?), and I've always enjoyed reading about that. Maybe one day I'll do something like that with Elka. Or one of those "kids read to dogs" programs (like Reading with Rover).
