Just as people need seatbelts, dogs deserve to ride safely too. Dr. Jamie Richardson of Small Door Veterinary says the most important element to keeping your dog safe is ensuring your dog is “secure and as immobile as possible” to avoid them becoming a projectile if an accident were to occur. 

As you shop for a seat or car harness, be sure to check that it’s the right size and weight capacity for your dog. It’s also a good idea to look for products that are independently tested and certified. 

Below, you’ll find the best dog car seats, according to our research and Dr. Richardson. 

Best Overall: Sleepypod Clickit Sport Dog Safety Harness

Sleepypod

What We Like
  • Designed to distribute pressure and reduce force if in an accident

  • Three points of contact secure your dog's torso

  • Comfortable for long-term wear

  • Doubles as a walking harness

What We Don't Like
  • Not ideal for sighthounds

According to Veterinary Jamie Richardson proper car restraint is essential to protecting your dog every time they ride in the car. Dr. Richardson recommends the Sleepypod Clickit Sport Dog Safety Harness for small, medium, and large dogs. This harness system works with your car’s seatbelt and is designed to distribute pressure and reduce force if you’re in an accident. Three points of contact secure your dog’s torso from all directions and reduce movement if you come to a sudden stop while driving.

Made from ballistic nylon, it is comfortable for even long-term wear and can double as a walking harness after your car ride is over. It comes in four sizes and four colors, so you can find the right fit for your dog. The Sleepypod Clickit Sport is one of the only harnesses that has been crash tested and meets the Center for Pet Safety's standards. According to Dr. Richardson, it may not be ideal for sighthounds (such as greyhounds), but it’s a great all-around harness to protect your pup in the car.

Best for Small Dogs: Sleepypod Mobile Pet Bed

Dimensions: 17 x 17 x 13-inches | Weight: 5.51 pounds | Material: Nylon | Type: Bed | Breed Size: Medium

What We Like
  • Works as a carrier, bed, and car seat

  • Great for dogs up to 15 pounds

  • Made from luggage-grade nylon and polyester

What We Don't Like
  • More expensive than other options

The Sleepypod Mobile Pet Bed is a great choice for smaller dogs, and while it’s a bit pricier than some other options on this list, it’s crash-tested and works as a carrier, a bed, and a car seat all at once. It’s ideal for placing in the backseat, and Dr. Richardson loves this pick for dogs up to 15 pounds.

Made from luggage-grade nylon and polyester, it includes a padded shoulder strap for carrying and a mesh dome top to allow air to flow in and out while your pet is inside. The water-resistant liner is easy to clean, and this pet bed can be used in both the car and on a plane. To secure during car rides, you can wrap a seat belt around the base and secure the belt through the bed’s handle. The medium size measures 17 x 17 x 13 inches, and weighs just over 5 pounds. 

Best For Large Dogs: A4Pet Pet Car Seat

Dimensions: 29 x 16 x 14-inches | Weight: 9.6 pounds | Material: Fleece | Type: Car booster | Breed Size: Large

What We Like
  • Large enough for labrador-sized pups

  • Elevates your dog 6.5 inches to look out the window

  • Double-sided for winter and summer use

  • Can double as a dog bed at home

What We Don't Like
  • May be too big for smaller dogs

According to Dr. Richardson, every dog car seat should secure your pup with a harness or a strap to avoid movement while traveling. The A4Pet Pet Car Seat is large enough for labrador-sized pups and measures 29 x 16 x 14 inches. It elevates your dog 6.5 inches above the car seat so he or she can look out of the window while you’re driving. It is two-sided, with cozy fleece for warmth in the winter and Oxford Fabric for cooling in the summer. A security leash keeps your pet in place while driving, and the fold-down design allows for storage when it's not in use.

Best Booster Seat: Pet Gear Large Car Booster

Pet Gear Booster

Dimensions: 22 x 17 x 11.5-inches | Weight: Not listed | Material: Suede | Type: Car booster | Breed Size: Small and medium

What We Like
  • Seat attaches via the car seatbelt

  • Secure and comfortable

  • Gives small dogs a boost to see out the window

What We Don't Like
  • Smaller than expected

When your dog can’t see out of the window, he or she may be tempted to jump around while you’re driving—which is distracting for you, and can be dangerous for them. The Pet Gear Large Car Booster gives your small or medium dog the boost they need to look outside while you’re driving and keeps them from trying to ride up front with you. The seat attaches to your car via the seatbelt, so it won’t move in place. It also features a tether that can be easily attached to a harness to keep your pet secure in the booster. The booster measures 22 x 17 x 11.5 inches and is ideal for dogs weighing up to 30 pounds. 

Owners love that this booster is secure and comfortable, but some do mention that it feels a lot smaller than might be expected. Dr. Richardson recommends booster and car seats to be placed in the backseat to avoid airbag damage, were an accident to occur.

Best for Trunks: Gunner Kennels G1 Large Crate

You can rest assured this crate is escape-proof and completely secure against force. It has in-line wheels for easy transportation to the car, and the large size measures 40.25 x 28 x 33.25 inches. 

Though this crate is pricey, it’s by far the most secure and strongest option if you're going on long car rides. It gets a 5-star crash test rating from the Center for Pet Safety.

The best place for your dog is in the back seat, away from the airbag. The Vailge Waterproof Dog Car Seat Cover is ideal for multiple dogs, especially if you are traveling often. This car seat hammock covers your entire back seat and not only protects your car from mud and dirt, but also keeps your pet from roaming around while you’re driving.

Two side flaps cover the sides of your car seat and make it easier for your pet to get in and out of the car.

The hammock measures 60 x 56 inches, and is ideal for a car or smaller SUV.

Final Verdict

Our best overall pick is the Sleepypod ClickIt Sport Crash-Tested Car Safety Dog Harness (view at Amazon), which has three points of contact to secure your pup's torso. If you're looking for an option for multiple dogs, check out the Vailge Waterproof Dog Car Seat Cover (view at Amazon). Large enough to cover your entire back seat, it effectively protects your car from mud and dirt.

What to Look for in Dog Car Seats

Independent Testing

Although many dog seat and harness manufacturers claim their products are “crash tested,” there’s no single industry standards for pet car restraints. It’s best to look for crash testing that’s been conducted by third-party organizations, like the Center for Pet Safety.

Size

Be sure to check the weight and size guidelines of the doggy car seat, to ensure it will fit your pet securely and comfortably. If a harness or seat is too big for you dog, he or she may be able to wriggle out during the ride, creating a distracting and dangerous situation.
