Consider using a dog seatbelt harness, a pet carrier, or a car safety barrier to restrain your dog while driving.
The back seat is generally safer for dogs than the front seat because it reduces the risk of airbag-related injuries in case of an accident.
If you're using a pet carrier or crate, make sure it's the appropriate size for your dog. It should be large enough for your dog to stand, turn around, and lie down comfortably.
Dogs should not be allowed to stick their heads out of car windows. Debris or insects can cause eye or ear injuries, and in an accident, the wind pressure can be harmful.
On long trips, plan regular breaks to allow your dog to stretch its legs, relieve itself, and have some water and food. Always keep your dog on a leash during pit stops.
It's best to feed your dog a few hours before the trip and avoid feeding while the car is moving.
Place a comfortable blanket or pet bed in the back seat or crate to make your dog feel secure and reduce anxiety during the ride.
Pack your dog's essentials, such as food, water, medications, and any comfort items, for the journey. Also, have a copy of your dog's medical records and identification tags on hand.
