A dog car seat keeps your dog in one place, off your lap and away from the gear stick, and lifts a small dog high enough to see out. That's genuinely useful. But it's worth being honest from the start: most dog car seats are comfort and anti-distraction gear, not crash protection. When the Center for Pet Safety crash-tested popular booster seats, they performed poorly. This guide shows which products are crash-test certified, and how to use a booster sensibly if that's what your dog needs.

Crash tested dog car seat: what the testing actually found
The Center for Pet Safety (CPS) crash-tests pet travel products. In its testing of four popular booster seats (PupSaver, Snoozer Lookout I, Top Paw and Kurgo Skybox), none earned a Top Performer result. The PupSaver rotated and rolled onto its side, and its instructions recommended the front seat, which CPS calls unsafe because of airbags.
What that means for you:
- A booster seat is not crash protection. Don't buy one expecting it to protect your dog in a collision, whatever the box says.
- "Crash-tested" on a listing isn't the same as CPS certified. Some brands run their own tests. Look for CPS certification.
- The only CPS-certified "seats" are small Sleepypod carriers, for dogs up to 15 lb.
- For large dogs there is no certified car seat. The safer options are a CPS 5-star harness like the Clickit Sport, or a crash-rated crate (see our heavy duty dog crate picks: the Gunner G1 and Lucky Kennel carry a 5-star CPS crash rating per K9 of Mine).
Three rules for any dog in any seat: ride in the back seat, never the front (airbags); clip the tether to a harness, never a collar; and keep the tether short enough that your dog can't reach the footwell or the front seats.
Sleepypod Mobile Pet Bed
Best for: small dogs up to 15 lb, when safety comes first.
The Mobile Pet Bed is a bed, carrier and car seat in one. Sleepypod carriers were the first pet restraints to meet CPS crash-test guidelines, and CPS rates the Mobile Pet Bed for dogs up to 15 lb. At home it's a cozy bed, so your dog already knows it before the first trip.
What we like
- CPS crash-test certified, rated to 15 lb
- Works as a bed, carrier and car seat
- Light at 4.5 lb
Keep in mind
- Small dogs only
- Expensive for a carrier
- Enclosed, so your dog can't look out of the window
Key specs: 17"W × 13.5"H · 4.5 lb (maker) · rated to 15 lb by CPS · smaller Mini (to 7 lb) and Atom (to 12 lb) also exist
Large dog car seat alternative: Sleepypod Clickit Sport
Best for: medium and large dogs who ride on the back seat.
There isn't a certified large dog car seat, so for big dogs we recommend this instead. The Clickit Sport is a crash-tested harness that CPS lists as certified, and it's the only harness with a CPS five-star rating in each size. It has three points of contact with the seatbelt and works as a walking harness too.
What we like
- CPS certified, 5-star in every size
- Three points of seatbelt contact
- Doubles as a walking harness
Keep in mind
- It isn't a "seat": your dog sits or lies on the car seat itself (a back seat cover for large dogs protects the upholstery)
- Fitting is fiddly the first few times
- Pricier than a standard harness
- Weight ratings per size vary between sources: check the maker's size chart against your dog's weight and girth
Key specs: harness with three points of seatbelt contact · several sizes · CPS certified
Dog booster seat picks (comfort, not crash protection)
The seats below are not crash-tested or CPS certified. They're good at keeping a small or medium dog settled, contained and able to see out. Always pair them with a harness and the back seat.
K&H Bucket Booster Pet Seat
Best for: small and medium dogs who like to see out.
CNN Underscored lists the Bucket Booster among its top dog car seats. It raises your dog about 5", the seat belt threads through loops in the base to hold it in place, and it's built from closed-cell foam with a washable cover. K&H says the Large fits one medium dog or two small ones.
What we like
- Raises your dog about 5" to see out
- Seat belt threads through the base
- Washable cover
- Large size fits two small dogs
Keep in mind
- Not crash-tested
- CNN Underscored found the soft foam build less sturdy for long-term use
- No stated weight limit
Key specs: Small 18×18×16" · Large 22×20×16"
Kurgo Skybox Rear Seat Booster
Best for: small dogs up to about 30 lb who run warm.
A raised box with a tether, widely stocked, with a lining CNN Underscored found cooler than many. It's one of the most familiar boosters on the market.
What we like
- Raised so a small dog can see out
- Cooler lining for warm dogs
- Built-in tether
Keep in mind
- Not CPS certified. The Skybox was one of the boosters in the CPS test with no Top Performer result
- CNN Underscored's tester found the velcro base wobbly and saw stitching come loose
Key specs: about 15.5"L × 12.5"W × 8.5"H · max about 30 lb
Petsfit Dog Car Booster Seat
Best for: medium dogs too big for most boosters.
Petsfit's booster is sized for medium dogs and has a washable pad. Weight limits vary by size, so check the listing against your dog before you buy.
What we like
- Sized for medium dogs
- Washable pad
Keep in mind
- Not crash-tested
- Check the weight limit on the listing for the size you pick
Key specs: washable pad · medium-dog sizing (check listing)
Snoozer Luxury Lookout Dog Car Seat
Best for: small dogs who love the view, and owners who want a plusher seat.
The Lookout raises your dog so they can see out, has a machine-washable cover and a handy storage tray.
What we like
- Raised for the view
- Machine-washable cover
- Storage tray for leash and treats
Keep in mind
- Not crash-certified. The Lookout I was among the seats CPS tested with no Top Performer result
- Bulky for a small-dog seat
Key specs: raised seat · washable cover · storage tray
Small dog car seat: how to choose
If safety in a crash is the priority
For dogs up to 15 lb, a CPS-certified Sleepypod carrier is the answer. It's less fun for a dog who likes the view, but it's the only certified option.
If your small dog gets anxious or restless
A booster seat that lets them see out, plus a short tether to a harness, keeps many small dogs calmer and off your lap. Just don't treat it as crash protection.
Check these on every booster
- How it attaches: the seat belt should thread through the base or straps, so the seat can't slide.
- Tether: short, with a swivel clip, attached to a harness.
- Fit: your dog should be able to sit and lie down without spilling over the edge.
- Washable cover: car sickness and muddy paws happen.
Large dog car seat options
For dogs over about 30 lb, there's no booster that fits well and no certified seat. Your realistic choices:
- A CPS-certified harness like the Clickit Sport, on the back seat, with a seat cover underneath.
- A crash-rated crate, secured in the cargo area. Rotomolded kennels like the Gunner G1 and Lucky Kennel carry 5-star CPS crash ratings per K9 of Mine; see our heavy duty dog crate guide.
- Getting in and out: if your big dog struggles to jump into the car, a dog ramp for the car helps.

FAQs
Are dog car seats safe in a crash?
Most aren't designed or proven to protect in a crash. In Center for Pet Safety testing of four popular booster seats, none earned a Top Performer result. The only CPS-certified seats are small Sleepypod carriers for dogs up to 15 lb.
Is there a crash tested dog car seat for large dogs?
Not a certified seat. For large dogs, use a CPS-certified harness like the Sleepypod Clickit Sport on the back seat, or a crash-rated crate secured in the car.
What is the best small dog car seat?
For crash safety, the Sleepypod Mobile Pet Bed (CPS certified to 15 lb). For a small dog who wants to see out, a booster like the K&H Bucket Booster or Kurgo Skybox, used with a harness on the back seat, but these aren't crash protection.
Do dog booster seats work?
They work for what they're good at: keeping a small dog contained, off your lap and able to see out, which can make the drive calmer for both of you. They don't protect your dog in a crash.
Can my dog ride in the front seat in a car seat?
No. CPS calls the front seat unsafe because of airbags. Put any dog car seat, carrier or harness setup in the back seat.
Choose for safety first, comfort second, and never skip the harness and the back seat. Your dog gets a calmer ride, and you get to keep your eyes on the road.
