It will be more convenient to feed dry food if the pet is used to it. Dispose of unused canned food unless it can be refrigerated. Take along a plastic jug of cold water to avoid possible stomach upset the first day. Give small portions of both food and water and plan to stop every two hours for exercise. And remember to include a leash in your travel kit.
Most states prohibit animals on buses, and recent rules now prohibit animals on trains.
Exceptions are generally made for seeing-eye dogs accompanying blind persons. Inquire in advance with local carriers. With Pets Be careful, skunks, porcupines, snakes, and other creatures can bite or injure your pet. Therefore, keep your animal in sight and on a leash. Be considerate of other campers.
