A crash-tested harness is the most flexible way to keep your dog safe in the car, especially when you're adding a car seat to the back row. Not every "crash-tested" harness holds up in a real crash. Every harness on this list has been tested, either by the Center for Pet Safety (CPS) or at an independent testing facility, so you can pick by your dog's size, your car, and your budget.
The safest dog car harnesses are certified by the Center for Pet Safety (CPS), like the Sleepypod Clickit Sport Plus, Sleepypod Clickit Range, and Säker Bomber. The Kurgo Tru-Fit and CarSafe are budget-friendly picks, crash-tested to the U.S. child car seat standard.

Best for: Dogs who are comfortable in the car, medium to large breeds, and families who need flexibility in seating arrangements.
Most crash-tested harnesses attach to your car's seat belt. You thread the belt through the loops or handles on your dog's back, then buckle it as usual. Some, like the Kurgo Tru-Fit, clip onto the seat belt with a carabiner instead. Optimus Gear's Large and XL connect to the car's LATCH anchors. Because the seat belt moves with your dog, where your dog sits decides what they can reach.
Never attach a seat belt or tether to your dog's collar or a regular walking harness. In a sudden stop, all the force lands on your dog's neck or on straps that weren't built for a crash.
Thread the seat belt through the harness exactly as the maker instructs, and remove the slack. Never add an extension tether or zipline. CPS says these increase the risk of injury and cancel out a harness's crash protection. Never attach your dog's harness to the car seat, or to anchors the car seat is already using. Check your car's manual for which anchors you can use.
The difference in price between crash-tested harnesses is significant, with options ranging from $20 to over $100. Every harness listed below has undergone crash testing - either through the Center for Pet Safety (CPS) or at certified facilities using child car seat safety standards. The ones certified by CPS are labeled.
A well-made, everyday harness at a genuinely great price. This is a Dog Meets Baby community favorite!
Sizing: 3 sizes (S, M, L), 10-80 lb
Crash testing: Crash-tested for dogs up to 75 lb at a university lab, to FMVSS 213 (Kurgo). Not CPS-certified: it didn't pass CPS's 2013 study. Kurgo has since redesigned it, and CPS hasn't retested the new version.
A step-in harness with a padded chest plate that doubles as a walking harness (with a no-pull D-ring), so you don't have to switch harnesses at a rest stop.
Sizing: 4 sizes, for dogs up to 100 lb (crash-tested specifically to 22 lb)
Crash testing: Crash-tested at the University of Michigan Transportation Research Institute following children's car seat safety standards.
A durable harness that families with medium and large dogs love for road trips and outdoor adventures. Good to know: the heavy-duty chest piece makes it a bit bulkier, so it can be less comfortable for smaller dogs.
Sizing: 4 sizes, 15-70 lb
Crash testing: Crash-tested to 70 lb at an OVSC-registered lab, to FMVSS 213.
The seat belt attaches low on your dog's back, which Ruffwear designed to keep dogs upright in a crash. Aluminum buckles make it easy to put on and take off.
Sizing: 5 sizes, based on girth
Crash testing: Tested at MGA Research, an independent lab, to FMVSS 213 with 25, 45, and 75 lb crash dummies.
Already own a Thule stroller, roof box, or bike rack? Thule now makes a crash-tested dog harness too. Made from 100% recycled fabric with a step-in design.
Sizing: 3 sizes, up to 75 lb
Crash testing: Crash-tested and TÜV SÜD certified.
Lola wore this for two years in our minivan, and we both loved it! The bundle includes the S-Clip and Buckle Shield, which stop your dog from accidentally sitting on the buckle and releasing mid-drive (yes, this actually happens).
Sizing: 4 sizes, 18–90 lb
Crash testing: CPS-certified, 5 stars, rated to 90 lb.
"We've done about 50k miles in the car with these harnesses, they have definitely worked during a couple hard stops and kept her from slamming into the seat in front of her. They did take some getting used to as they have less freedom of motion than some harnesses, but worth it for the additional safety. She currently wears an XL, 73lb GSD." - Christina, Sleepypod Clickit Sport Plus owner (Chewy review)
Comes in two fits: Regular for most dogs, and Long, designed for narrow, deep, and barrel-chested dogs (think Greyhounds and Bulldogs). The Long fit was CPS-certified using a new crash-test dog modeled on sighthounds. Comes with the S-Clip and Buckle Shield, so your dog can't accidentally release the buckle mid-drive.
Sizing: 5 sizes in regular or long fit, 18–110 lb
Crash testing: CPS-certified, 5 stars, tested with a 110 lb dog
Hela and Izzy both ride in this one. A great choice for families who travel often. It's not a dedicated walking harness, but on a road trip or a longer drive, you can clip a leash to it for a walk break without taking it off. Watch this reel to see how we use the EzyDog Harness.
Sizing: 3 sizes, 15-65+ lb
Crash testing: Crash-tested with 28, 50, and 75 lb dogs at Automotive Safety Engineering in Australia, a facility recognized under the U.S. child car seat standard (FMVSS 213).

A trail harness that also works in the car. The neck buckle opens, so nothing goes over your dog's head.
Sizing: 4 sizes (XS–L)
Crash testing: CPS-certified, 5 stars, tested with a 75 lb dog.

Crash testing: Crash-tested to FMVSS 213 with a 110 lb test dog.
Discount: Use code DOGMEETSBABY for $10 off.
Two short tethers, one to the seat belt and one to the seat belt buckle (XS to Medium) or the car's LATCH anchors (Large and XL), help keep your dog positioned and stable in the seat during the ride. Good to know: Large and XL need a seat whose LATCH anchors aren't used by a car seat. Made in Canada.
Sizing: 4 sizes, Small to 75 lb; XL for 85 lb and up
Crash testing: Crash-tested to child car seat standards, per Optimus Gear. The XL isn't crash-tested yet.
Dog Meets Baby follower: "Our +80lb fur baby is always buckled in with his crash-tested harness! He sits in the same row as our 9mo son and behaves very well. I had to slam on the brakes, and I quickly learned how important it is to have him buckled in!"
Are there crash-tested harnesses for extra-large dogs? Yes. The Sleepypod Clickit Range is CPS-certified for dogs up to 110 pounds. The Big Dog Seat Belt Company also creates custom harnesses crash-tested with a 110 lb test dog.
What if my dog has learned how to unbuckle the seatbelt? Use a seat belt buckle cover or buckle guard. Sleepypod harnesses come with a Buckle Shield accessory. The Buckle Shield is placed over the buckle and will not allow your dog's foot to accidentally step down and push the button to release the seat belt. Morlike has a Buckle Safety Cover Lock. It's not specifically made for dogs.
How often should I replace my dog's car harness? Replace it after any accident, even a minor one, and whenever you notice wear, fraying, or damage to the stitching or hardware. Check your harness maker's guidelines for anything more specific.
