Ranger is the car version of a sweet Border Collie named.. well, Ranger. The dog is trained to sense anxiety attacks before it happens, like most service dogs do. The truck can already sense anxiety attacks because he knows me. He knows that when Bernie looks around, fidgets with things, scratches herself when she doesn't itch, stutters when she talks, talks too much, it means she's about to have an anxiety attack. Ranger knows Bernie is socially anxious, and usually helps get her out of crowds.
