Sickness or injury is the last thing you want to happen to any of your companions on a trip. But as everyone knows, things go wrong sometimes, and it's best to be prepared. If you're traveling in a car, you might already have a first aid-kit suitable for injuries to humans. When traveling with pets, you should also have one ready for the special needs of your pet. You can purchase premade pet first aid-kits in stores, or you can package one of your own from items you probably have at home.
If you want to take the do-it-yourself approach, the American Red Cross recommends the following basic supplies for any pet first aid-kit: gauze pads, gauze rolls and bandages, cotton swabs, instant cold pack, roll of cloth, tweezers, thermometer, hydrogen peroxide and antibiotic ointment [source: American Red Cross].
You can also include additional items, such as plastic gloves, scissors, mild pet sedatives, eyedroppers (for feeding) and bottled water. If the pet becomes seriously ill or hurt, take caution if attempting to treat it on your own. For major injuries, you may want to locate the nearest vet.
