<human>: What's a good way to keep my dog from chasing cars?
<bot>: A good way to keep your dog from chasing cars is to teach them the "leave it" command. Start by teaching your dog that when they hear the word leave, they should stop whatever behavior they are doing and move away from the car. You can use treats or verbal praise for reinforcement. Then, gradually increase the distance you ask your dog to leave the car before giving the command. Finally, practice with distractions such as people walking past or other dogs barking in order to help your dog stay focused on the car.
