Dog Safety Harness for Car Travel | Crash-Tested Options

The dog safety harness for car travel you pick matters more than most pet owners realize. A regular walking harness won’t hold up in a crash, and even many products marketed for car use fail independent testing. The good news is that a small number of harnesses have passed real crash tests, and choosing one of those is the single best thing you can do for your dog’s safety on the road.

What Crash Testing Actually Proves

The Center for Pet Safety (CPS), a nonprofit dedicated to pet product safety, conducted a landmark harness study in 2013, sponsored by Subaru of America. The testing combined static evaluation with dynamic crash testing based on FMVSS 213, the same federal standard used for child safety seats. The simulated impact was a 30 mph head-on collision.

The results were sobering. Out of all harnesses tested, only one earned CPS’s top rating. The Sleepypod Clickit Utility was identified as the top-performing harness, while every other product was deemed insufficient in design, materials, or overall performance. CPS published its formal test protocol, the CPS-001-014.01 guidelines, in July 2014.

How To Tell A Real Car Harness From A Walking Harness

The most common mistake dog owners make is treating a walking harness as a car safety harness. Here’s what separates a genuine crash-tested product from an ordinary one:

• Look for specific crash-test claims: A real car harness will name the standard it was tested against, like FMVSS 213, and state the test speed.
• Check for independent verification: A manufacturer’s own “tested” claim isn’t the same as passing a standardized crashworthiness evaluation. Products can be marketed with testing claims yet still fail under real crash conditions.
• Examine the hardware: Wide, durable, seat-belt-like straps and metal buckles are preferred over flimsy plastic clips.
• Confirm the attachment method: A safe harness attaches to the car’s seat belt system, not just to a headrest or door handle.

If a product doesn’t explicitly state its crash-test credentials, assume it’s a walking harness and keep it for walks.

Crash-Tested Harnesses Worth Knowing

The company also says the Clickit Sport was crash-tested to both the U.S. Child Safety Seat Standard FMVSS 213 and the European Union Child Safety Seat Standard ECE R4.

That said, there is no universal pet harness crash standard comparable to what exists for child restraints. Claims vary widely by manufacturer and testing protocol, so you have to read each product’s claims carefully. The CPS 5 Star rating remains the most meaningful independent verification available in the U.S. today.

Safer Alternatives To A Harness

If you’re not ready to commit to a crash-tested harness, safer alternatives exist. A pet seat belt attached to the car’s seat belt is a reasonable option, and a robust travel crate is also appropriate — provided it’s attached to the car and roomy enough for your dog to stand, turn around, and lie down. Pets in a regular passenger car typically travel in the cabin or the back of the car, where a properly secured crate can keep them safe.

Whatever restraint you choose, remember that no harness can protect a dog from every crash scenario. The goal is to give your dog the best possible odds, and a crash-tested harness remains the gold standard for that.

FAQs

Can I use a regular walking harness in the car?

No. Walking harnesses are not designed to withstand crash forces and failed or were deemed unsuitable in CPS testing. A crash can snap the straps or buckles, or the dog can slip free entirely. Use a harness specifically marketed and tested for car use.

How fast do the crash tests simulate?

The CPS harness study used a 30 mph simulated head-on impact. That speed is based on child-safety-seat testing methodology and represents a moderate collision. Real-world highway crashes happen at much higher speeds, so even a crash-tested harness has limits.

What does CPS 5 Star rated mean?

It means the harness passed the Center for Pet Safety’s standardized crashworthiness evaluation, which combines static testing with dynamic FMVSS 213-based crash testing. A 5 Star rating is the highest CPS rating and the strongest independent verification available for pet car harnesses.
