Max the GSD has separation anxiety in my car. When I get out he goes berserk. Anybody have advice? I can’t be the only one out there with a car-wild GSD. He recognises different food places as we pull up—starts crying, then tries to get out with me. He’s strong and driving me nuts. He’s turned into a really good dog except for the car and the front door. I know I should leave him at home, but I like having him with me.
