To calm an overexcited dog in the car, teach your dog to ride in the car calmly and comfortably so your travel companion becomes a first-rate passenger. This can be achieved through desensitization and counter-conditioning, which changes your dog’s emotional response from negative to positive by having great stuff happen near and inside the car. Depending on how severely your dog reacts, you might have to teach your dog to ride in the car starting from 10 feet away, while the car is parked in the driveway. You can also start with your dog on the back seat. At each stage of the process, give your dog something beloved like a special toy, delicious treats, or a meal. Only move closer when your dog is completely relaxed at the current stage. If your dog stops eating or playing, you’ve moved too fast. Be patient and move at your dog’s pace. Once your dog is comfortable in the car, you can add motion to the mix, starting with short distances and building up the time spent driving by short increments, making every trip as pleasant as possible. Praise your dog while you drive and use encouraging cheerful banter. For dogs that still experience motion sickness or anxiety, keep the temperature inside the car cool, lower the windows for fresh air, and limit your dog’s food and water for a few hours before the trip. Exercise your dog about twenty minutes before your trip to decrease stress and consider using dog pheromones to relax your dog.
