Be sure to bring food, bottled water, a traveling pet bed, and any toys or comfort items your pet enjoys at home.
You want your pet to be as comfortable as the rest of your family on the road. Car sickness is a very common incident, especially in puppies: While many dogs travel best with empty stomach, others respond better after eating a light meal, especially dogs that have one meal per day. Also make sure that you regularly stop and offer your pet some water. If you need to get out for a break and to stretch your legs, so does your pet - so don't leave him shut-up inside to freeze; take him with you.
Always make sure your pet is properly restrained inside the car with a traveling harness or pet carrier. If the animal is on a seat, unrestrained, then any sort of collision is likely to cause it to fly around the inside of the vehicle, probably injuring itself severely as it collides with headrests, the dashboard, or the occupants - or smashes itself through the windshield.
