Hi we are having some problems with my dog trying to chase and lunge at cars and it’s got so bad he has almost dragged me into the road a few times. We currently don’t walk him on roads but it happens when we are just taking him in and out of the car. We have tried to do some positive reinforcement training, taking him near cars and giving him treats when he stays calm, but sometimes he gets so worked up he struggles to calm down and we can’t get his attention. Have you got any tips? Thank you
