Our German Shepherd barks and lunges at the windows of our van she sees people, bikes or passing trucks. It makes car rides very challenging, how can we help her?

Hi Cindy, Would you please give me some advice? My 13-month GSD would bark like crazy and lunge at the windows from within our van ride at the passing by trucks, people standing at the crosswalk, people riding bikes! We popped her prong collar and told her “leave it” or “quiet” but she couldn’t stop as we saw her hair on her back standing up. It looks like she’s very panicky and scared. But when we took her out of the van and walked her, she’s totally fine with people, animals, and cars… but she always has a tendency to be a little reactive to big trucks, bikes and scooters. But not as dramatic like she’s inside our van. We tried to pop her (she only wears prong collar) but we thought it isn’t right to correct her if she’s scared… but this situation has been going on and getting worse. Car ride becomes very challenging. How may we help her and train her please? She is wearing pet seat belt sitting with us on our van. Thanks in advance!

Thanks Cindy! We followed your advice and she’s much better now as she’s only allowed to get in and out of our van with our permission and she stays in her own crate with a cover on it when we drive.  The barking on car ride seems to subside as well. Thanks!
