Verdict in brief: Most dog car harnesses claim to be “crash-tested” without independent proof. Sleepypod’s Clickit harnesses are among the few certified by the Center for Pet Safety, which makes them our top pick for owners who want real crash protection. They cost more than basic harnesses, and fit matters a lot.
Sleepypod Clickit
CPS 5-Star Certified Dog Car Harness, Crash-Tested Protection for the Back Seat
Overview: What the Clickit Is and How It Works
The Sleepypod Clickit is a vest-style car harness that connects to your car’s seatbelt, so your dog rides restrained on the back seat.
In a sudden stop, an unrestrained dog keeps moving at the car’s speed. The Clickit catches that force with a broad, padded chest vest and a three-point design that limits both forward and sideways movement. Because it uses the seatbelt directly instead of a long tether, there’s very little slack for your dog to build momentum.
What sets it apart is independent verification. The Center for Pet Safety tests pet restraints with the same kind of sled tests used for child car seats, and “crash-tested” on other brands’ packaging often means nothing more than the manufacturer’s own claim. The Clickit models hold 5-star CPS ratings.

Real-world rating: The Clickit Sport (Small, Strawberry Red) holds a 3.9 out of 5 rating from 210 Amazon ratings — a moderate, genuine sample rather than an overwhelming one. That’s worth factoring in alongside the CPS certification: the engineering is independently verified, but real-world owner satisfaction is solid without being exceptional.
Pros and Cons
Pros
- Independently certified by CPS, not just marketed as crash-tested
- Much cheaper and more compact than a certified crate
- Works with any standard seatbelt, so it moves easily between cars
- The Sport and Terrain double as walking harnesses
- Keeps your dog from distracting you while driving
Cons
- Costs several times more than basic harnesses — and more than some published starting prices suggest
- Only protects properly when sized correctly
- The Sport may not fit deep-chested breeds well
- Doesn’t contain a dog the way a crate does
- Some dogs need time to accept wearing it
Best Use Cases
Daily drives. It goes on quickly, which makes it practical for trips to the vet, park, or groomer.
Road trips. Your dog can sit or lie down on the seat while staying restrained.
Multi-car households and rentals. It packs small and needs nothing but a seatbelt.
Small cars. If a crate won’t fit your trunk, a certified harness is often the best option available.
It’s less suited to dogs that chew straps or owners who want full containment and have room for a crate.

What Owners Report
A few themes come up consistently in owner reviews and retailer notes. Build quality gets frequent praise, with sturdy webbing and hardware that feels more solid than budget harnesses. Fit is the most common issue: retailers warn that the Clickit Sport may not suit Greyhounds, Whippets and similar breeds, which is the gap the Clickit Range was designed to fill. Many owners also mention a short learning curve when routing the seatbelt, and an adjustment period before their dog relaxes in it.
Is It Worth the Price?
If crash protection is your reason for buying, yes. A cheap harness that fails in a collision offers little beyond keeping your dog in place on quiet roads. With the Clickit, you’re paying for published independent test results.
Two things improve the value further. The Sport and Terrain can replace a walking harness you’d otherwise buy separately, and Sleepypod’s Crash Replacement Program helps if the harness is ever in an accident. Any harness that has been through a crash should be replaced, even if it looks undamaged.
If you only need to stop your dog wandering the car on slow local drives, a basic harness — like the Kurgo Tru-Fit — is a reasonable budget choice, as long as you don’t treat it as proven crash protection at the same level as CPS certification.
How to Fit and Use It
Follow the manual for your model, since routing differs slightly between designs.
- Measure your dog around the widest part of the ribcage, just behind the front legs, and match it to the Sleepypod sizing chart.
- Put the harness on outside the car. You should fit two fingers under the straps, and it shouldn’t rotate or slip when pulled gently.
- Seat your dog in the back. A front airbag can seriously injure a dog even when the harness holds.
- Route the seatbelt through the harness as shown in the manual and buckle it.
- Remove the slack so the belt is snug. Sleepypod’s included S-Clip helps keep the belt locked.
- Fit the buckle shield if your dog tends to paw at the seatbelt release.
Never attach a car restraint to your dog’s collar, since all the crash force would land on the neck.
To help your dog adjust, let them wear it at home with treats, then sit buckled in a parked car, then take short drives before longer ones.
How It Compares
| Option | Best for | Trade-off |
|---|---|---|
| Sleepypod Clickit | Certified protection without losing cargo space | Needs correct sizing; pricier than initially advertised |
| Kurgo Tru-Fit | Budget-friendly with a specific, named test claim (Calspan) | Not confirmed on CPS’s own certified list |
| Uncertified harness | Budget restraint on local drives | No independent crash data |
| Gunner G1 Kennel | Maximum containment | Expensive, heavy, needs space |
Note that the Gunner G1 Small, Medium and Intermediate crates are certified only when used with Gunner’s strength-rated anchor straps.
Final Verdict
The Sleepypod Clickit is the harness we recommend for most owners who want crash protection they can verify. Here’s how to choose:
- Small dogs under 25 lb: Clickit Sport, Small
- Average-build dogs up to 90 lb: Clickit Sport
- Large or active dogs up to 110 lb: Clickit Terrain
- Deep or barrel-chested dogs: Clickit Range
- Tight budget, local driving only: a basic car harness used in the back seat
- Maximum protection with space to spare: a CPS-certified crate
Whichever you pick, measure carefully, keep your dog in the back seat, and check the current listed price before assuming the lowest figure you’ve seen quoted.
FAQ
How do I confirm a harness is CPS-certified? Check the exact model and size on the Center for Pet Safety website. Certifications apply to specific sizes and can change over time.
Can I use a regular walking harness in the car? Not safely. Walking harnesses aren’t built for crash forces, and their stitching and clips aren’t rated to handle that kind of impact.
Can my dog ride in the front seat with a harness? No. A deploying airbag can seriously injure a dog even if the harness holds — always keep your dog in the back seat.
