There is 1 rescue dog (her name is Callie) with the Kentucky team (123 STS), they justify her with their state search and rescue mission (last I heard, she is the only SAR dog in the DoD). She has been jumped, rappelled, fast roped and been around just about every type of training environment you can imagine. The handler is a full-time PJ on the team. The dog lives with him and travels on every TDY. The amount of work required to do this is pretty intense and isn’t very feasible by the active duty units with our current design.
Callie actually has an Instagram (@sar_pup) if you want to see her in action.
