How to Choose a Crash Tested Dog Car Harness: What the Test Results Actually Mean

A harness can be marketed as crash tested and still never have survived a real crash simulation. The label language is unregulated and manufacturers write it themselves. The Center for Pet Safety (CPS) publishes actual harness results, and its certified list is short — currently three 5-star harnesses.

What Does “Crash Tested” Actually Prove?

Almost nothing on its own. CPS states a product can be crash tested by the manufacturer without being certified or proven effective in an independent test, and the phrase carries no legal definition.

A credible result names four things: the protocol, the lab, the test speed, and the pass/fail or star outcome. CPS’s harness study used a safety-harness crashworthiness protocol built specifically for pets — not a repurposed human seatbelt standard. Pet products cannot simply pass crash testing by being measured against human federal or European standards alone, because a dog’s body geometry and restraint points differ. A manufacturer citing FMVSS 213 shows the hardware was built toward a real standard — Sleepypod’s Clickit Sport Plus, for example, is described as crash tested to U.S. FMVSS 213, Canada CMVSS 213, and EU ECE R4 child safety standards — but the standard alone is not a pass result.

Reading a Test Result the Right Way

A useful result is specific enough that you could verify it. Ask for the test date, the size and weight rating, and whether the outcome comes from independent certification or only a manufacturer’s claim. Common traps:

• Treating “crash tested” as “safe.” The label does not require a passing outcome.
• Assuming a human-standard pass transfers. A harness validated against human standards still needs pet-specific crash evidence.
• Ignoring the weight ceiling. Every certified harness is rated to a maximum, and exceeding it voids the result.
• Confusing restraint types. Harnesses, carriers, and crates are different systems with different protocols.

Why CPS Certification Is the Standard That Matters

CPS is the one body that publishes harness results against a pet-specific crashworthiness protocol, and its 5-star list is deliberately short: Sleepypod Clickit Sport, Sleepypod Clickit Range, and the Saker Bomber Harness. The 2013 CPS study named the Sleepypod Clickit Utility the top-performing harness in that round, which is why it still appears in older comparison charts — but it is not on the current certified list. Certification lists change, and a result from 2013 carries less weight than one from 2022.

Cost is not a signal of certification either.

Before you buy: a certified harness is certified for a specific size range and must be used exactly as directed. Match the rating to your dog’s weight, confirm the harness has not been discontinued or revised since its test date, and treat any product whose only claim is “crash tested” as unproven until you find the protocol and the outcome.
