Taking along your own food, water, toys, first-aid items, and other gear will simplify traveling with your pet.
A car trip or vacation with your pet will go much more smoothly if you have plenty of supplies on hand to keep it happy and occupied. Consider basic needs, such as food, water, and portable dishes for eating and drinking, and also fun items, such as treats and toys. First-aid items such as gauze, iodine, antibiotic ointment, and insect-sting swabs can be invaluable, as can a motion-sickness treatment such as the homeopathic formula Calm Stress. Other items you should include are a portable pet bed, leashes, disposable pooper-scoopers, grooming tools such as brushes and combs, and a toothbrush and toothpaste formulated especially for your pet.
