To keep a dog safe in the car, secure them the same way you secure people: use a crash-tested harness attached to a seat belt, or a properly secured crate. Keep your dog in the back seat, prevent distractions, and never leave your dog in a hot parked car—even for a few minutes.
Why Dogs Get Hurt in Cars
Most problems come from two things: crashes and heat. An unrestrained dog can become a projectile in a crash, get thrown from the car, or hit the dashboard. Heat is the other big risk—cars warm up fast and dogs overheat quickly.
1) Use the Right Restraint (Best Option for Most Dogs)
The goal is simple: stop your dog from flying forward in a sudden stop or crash, and keep them from distracting the driver.
Option A: Crash-tested harness + seat belt
A dog car harness that clips into a seat belt keeps your dog in place and reduces injury risk.
- Choose a harness made for car travel (not a regular walking harness).
- Attach it to the seat belt, not to the collar (collar can injure the neck).
- Adjust the harness so your dog can sit/lie down but can’t roam.
Option B: Secured crate/carrier
A crate can be a great solution for dogs that feel safer enclosed. It also helps with mess, anxiety, and motion sickness.
- Use the right size: enough room to turn and lie down, not oversized.
- Secure the crate so it can’t slide.
- Place it in the back seat or cargo area (depending on vehicle) and keep airflow good.
Where Should the Dog Sit?
The back seat is usually the safest place for most dogs. Front seats can be dangerous, especially because airbags can seriously injure a dog in a crash.
2) Keep Your Dog From Distracting the Driver
Distractions are a safety issue for everyone in the car.
- Use a restraint so your dog can’t climb into the front.
- Keep toys simple and safe (avoid choking hazards).
- Stop for breaks instead of trying to manage behavior while driving.
3) Hot Car Rules (Most Important for Summer)
A parked car can become dangerously hot quickly. Cracking windows is not enough. Dogs can overheat fast, and it can become a medical emergency.
Do this instead:
- Run errands without your dog when you’ll need to park and leave the car.
- If you must travel in heat, plan shaded stops and bring water.
- Use AC while driving and watch for overheating signs (heavy panting, drooling, weakness).

4) Safe Trip Setup (Before You Start the Car)
A simple setup makes rides safer and calmer.
- Pack water and a collapsible bowl.
- Bring a leash for safe breaks.
- Use a seat cover or towel for comfort and grip.
- Keep windows up enough so your dog can’t jump out.
- Avoid letting your dog stick their head far out the window (debris + injury risk).
5) Motion Sickness and Anxiety Tips
Some dogs get car sick or anxious. Safety comes first, but comfort matters too.
- Start with short rides and reward calm behavior.
- Keep airflow steady and avoid strong smells.
- Don’t feed a big meal right before travel.
- If anxiety is severe, talk to your vet.
6) What to Do if You Have a Crash With a Dog in the Car
Dogs can bolt when scared, even if they’re usually calm.
- Stay calm and secure your dog on a leash before opening doors.
- Check for injuries and call a vet if you see limping, bleeding, or shock signs.
- Move your dog away from traffic if it’s safe.
- If your dog is trapped, don’t force them—get help.
