Top Safety Harnesses for Dogs in Cars

Whether you’re exploring Canada’s scenic highways, navigating tight turns in Tokyo, or heading to a weekend getaway in the Italian countryside, your dog’s safety in the car should never be an afterthought.

Just like humans need seatbelts, dogs need crash-tested safety harnesses. In a sudden stop or collision, an unsecured pet becomes a projectile—posing a serious risk to themselves and everyone else in the car. In fact, many countries now require pet restraints by law, including the UK and Germany.

📏 How to Pick the Right Size

• Measure chest girth and weight
• Refer to brand-specific sizing guides
• Adjust straps for a snug (not tight) fit

🛡️ What to Look For

• Crash testing and certifications (e.g., CPS-certified, EU standards)
• Strong hardware (metal clips, nesting buckles)
• Padded chest plate for impact absorption
• Ease of installation and adjustment

🔗 Harness-Only vs. Harness + Seatbelt Systems

• Harness-only: Some models need a separate tether or seatbelt loop
• Harness + Seatbelt: Integrated systems (like Sleepypod) provide better stability and reduce setup time

G7 Tip: Choose a system compatible with both your vehicle and your country’s safety regulations. For example, Germany’s road safety law requires restraints that don’t allow dogs to roam freely.

🇨🇦 Canada & 🇺🇸 USA

• Great for long-haul road trips—think Banff to Vancouver or coast-to-coast in the US
• Prioritize comfort and crash-testing for hours on the road

🇬🇧 UK & 🇩🇪 Germany

• Legally required to restrain pets in vehicles
• Best to use harnesses with certified crash protection

🇯🇵 Japan & 🇮🇹 Italy

• Small car interiors mean space-saving harnesses are ideal
• Prioritize lightweight models that work well in compact vehicles

Are dog seatbelt harnesses legally required?

Yes, in some G7 countries:

• UK: Rule 57 of the Highway Code mandates secure restraint
• Germany: Pets must be restrained as “cargo”
• Other countries: Laws vary, but pet safety is often linked to distracted driving rules

How do I know if a harness is crash-tested?

Look for:

• CPS Certification (Center for Pet Safety)
• Crash test data from third-party labs (MGA, TÜV)
• Manufacturer claims alone aren’t enough—check for test results and videos

Can I use the same harness for walking and driving?

It depends:

• Dual-use models (like Kurgo and Sleepypod) are designed for both
• Some crash-tested harnesses are too bulky or specialized for everyday walks

A quality, crash-tested dog car harness is one of the most important investments you can make for your pet’s safety. It protects them in emergencies, keeps them secure during sudden stops, and helps you focus on the road.
