How to Fit a Dog Car Seat: A Step-by-Step Guide for Safe and Stress-Free Travel

Let’s face it—dogs are terrible drivers. That’s why they ride shotgun (or in the back seat). But when your furry friend is bouncing around like a furry pinball during every roundabout or sudden stop, it’s time to introduce them to something game-changing: the dog car seat.

A properly fitted dog car seat isn’t just about keeping your upholstery clean—it’s about safety, comfort, and peace of mind. Whether you're popping to the park or heading off on a long road trip, this guide will walk you through exactly how to fit a dog car seat—with no stress, no drama, and no chewed seatbelts.

🐶 Why Use a Dog Car Seat?

Before we dive into the how, let’s talk about the why.

Here’s what a dog car seat does for you and your pup:

  • Keeps your dog secure during sudden stops or accidents

  • Prevents them from distracting the driver (you know who you are, lap riders)

  • Offers a cosy, elevated seat so they can look out the window

  • Reduces motion sickness for many small breeds

  • Protects your car seats from fur, mud, and the occasional paw print masterpiece

And yes—it also keeps the law on your side. In the UK, Rule 57 of the Highway Code says dogs must be restrained while travelling to avoid injury and driver distraction. A dog car seat ticks that box.

🧰 Step 1: Choose the Right Type of Dog Car Seat

Not all dog car seats are the same. Pick the one that suits your dog’s size, personality, and travel needs.

🐾 Booster seat (for small dogs)

These raised seats allow little dogs to look out the window while staying strapped in. Ideal for pups under 10kg.

🐾 Bucket-style seat

Deep, soft-sided seats that work well for medium-sized dogs or nervous travellers. They often have padding and safety tethers.

🐾 Hammock-style seat cover

Great for larger dogs who like to stretch out on the back seat. Not technically a seat, but often used alongside a harness.

👉 At Paw Comfort UK, we stock easy-to-fit booster and padded bucket seats designed for UK cars and dogs of all shapes and fluffiness levels.

🪢 Step 2: Find the Best Spot in Your Car

Most dog car seats are designed for the back seat, which is the safest place for your pup.

  • Avoid the front seat unless the airbag can be disabled—airbags can be dangerous for dogs during impact.

  • Use behind the passenger seat so you can still keep an eye on them.

  • If using a booster seat, make sure your dog can see out without straining or standing.

🔧 Step 3: Secure the Dog Seat to Your Vehicle Seat

Now for the setup. Here’s a general process that works with most car seats:

  1. Place the dog car seat on the vehicle seat, making sure it sits flat.

  2. Thread the car’s seatbelt through the base or rear straps of the dog seat.

  3. Buckle the seatbelt in and pull it tight—no wobbling allowed.

  4. Use any included anchor straps to attach the seat more securely (some loop around the headrest).

  5. Double-check for a snug, stable fit. The seat shouldn’t slide around when you tug it.

If your seat has adjustable height or back padding, now’s the time to tweak it for your dog’s comfort.

🔗 Step 4: Attach Your Dog’s Harness to the Seat

Most dog car seats come with a built-in safety tether. This is where many people go wrong: never clip it to your dog’s collar.

Always use a well-fitting harness, preferably a crash-tested one, and clip the tether to the back of the harness. This keeps your dog secure without choking them if you brake suddenly.

Not sure if your harness is travel-safe? Look for wide chest panels and padded straps—these spread pressure more evenly during sudden stops.

🧸 Step 5: Add Comfort for the Ride

You wouldn’t ride in a bare plastic seat, and neither should your dog.

  • Add a soft blanket or cushion to the seat (machine washable is a bonus).

  • Bring a favourite toy to make the space feel familiar.

  • Make sure they have good airflow but aren’t right next to the air vents.

  • For longer journeys, bring a portable water bowl for pit stops.

The goal is to make the car seat feel like a mini lounge on wheels—not a punishment corner.

🛑 Bonus Tips: Travel Like a Pro

  • Always do a short test run before a long journey—let your dog get used to the seat.

  • Clean the seat regularly to avoid smells, fur build-up, or mystery crumbs.

  • Never leave your dog alone in the car, even in mild weather.

  • Check the fit every few months—especially if your dog is still growing or your car setup changes.

Dogs are creatures of habit. Once your pup gets used to their car seat, they’ll often hop in on their own, ready for the next adventure.
