I found a place somewhat nearby (about an hour and a half) that does herding with german shepherd!

I think I am going to get Nash's instinct test done at some point and train with him if he has an interest in it, if the guy will let us. I'm not sure if he will train with a rescue or not, and I don't know how much $$ it costs. It would be really cool to do though
