I know someone you should talk to! Her name is Michelle, and she breeds GSDs and trains dogs for service work, and has had clients with PTSD. The icing on the cake, her dogs carry the long coat gene so you have a shot at a long coated puppy! She's in WI, so big terribly far from OH. She's super nice and will be honest with you on whether she thinks you'll be a good fit for one of her dogs.
