How to choose a dog crate for your car

Using a dog crate in the car isn’t just about convenience, it’s about safety. In the event of a sudden stop or accident, a properly installed crate can help protect both your dog and passengers. It also prevents your dog from moving around the vehicle, allowing you to stay focused on the road. In some countries, restraining your dog during car travel is also required by law. A crate provides a secure and familiar space for your dog and makes it easier to handle muddy paws or wet fur after outdoor adventures.

 

Key features to look for in a car dog crate

Not all crates are suitable for car travel. When choosing a car dog crate, look for features designed specifically for vehicle use:

Crash protection: A crash-tested crate is the safest option. Look for products that meet or exceed safety standards for rear-end collisions, like out Thule Allax range.

Secure installation: The crate should fit snugly in your car and be easy to secure using tie-down straps or anchor points.

Ventilation and visibility: Proper airflow is important, especially during longer trips. Windows or openings allow your dog to see you and stay comfortable.

Escape-proof design: A secure locking mechanism ensures that your dog stays safely inside, even in unexpected situations.

Quiet ride: Some crates are built with materials or features that minimize rattling or movement inside the vehicle.

Easy to clean: Removable mats or trays help you manage dirt, hair, or spills.

At Thule, we know how important your dog is to your life, and how important safety is when you’re on the move. That’s why we’ve developed a range of dog crates for cars designed to meet the highest standards of safety, comfort, and quality.

Thule Allax

Thule Allax is a crash-tested dog car crate that’s designed to fit seamlessly into most car trunks. It features an adjustable depth, a quiet and stable ride, and a smart design that makes it easy to use every day. The door opens with one hand, and the crate includes built-in ventilation and escape-proof locks.

 

Thule Allax threshold compatible

This version of Thule Allax is made for cars with a high trunk lip or threshold. Thanks to the modified frame and elevated door, your dog can enter and exit the crate more easily — without the door hitting the bumper or threshold when opened.

 

Coming soon: Thule Allax double

Got two dogs? The upcoming Thule Allax double will offer the same crash protection and clever design features, in a wider crate that fits two dogs side by side.

Choosing the right size is one of the most important steps in finding the best dog crate for car travel. A crate that’s too small can be uncomfortable for your dog, while one that’s too large may move around in the car or reduce safety in a crash.

Follow these steps to get the right fit:

Measure your dog

To ensure the crate is the right fit, measure your dog’s wither height (the height from the ground to the top of the shoulder blades).

 

Check your car’s dimensions

Measure the depth from the back seats to the end of the trunk, and the height from the floor to the lowest point of the door or ceiling, noting any sloping or low-hanging edges.

 

Use the Thule fit guide

Our online tool makes it easy to find the best-fitting Thule Allax model based on your car and your dog’s size.

The right accessories can make car travel even easier. Here are four smart add-ons for your Thule dog crate:

Thule bumper protect

Protects your car bumper from scratches when your dog jumps in and out. Doubles as a sunshade and folds easily when not in use.

 

Thule dog mat

A silicone, non-slip mat that gives your dog a stable surface and added comfort.

 

Thule dog crate storage bag

Attaches to the crate with velcro and keeps all your dog’s travel items organized and close at hand.

 

Thule leash hook

Keeps your dog’s leash and collar in one place. Can be attached anywhere on the crate.

If your car isn’t suitable for a crate, or if you simply prefer a more flexible option, a car harness is a good alternative or addition. A crash-tested car harness helps restrain your dog in the back seat and keeps them secure during travel.

 

Our dog travel harness is designed for safety and comfort. It attaches easily to the seatbelt, letting your dog sit or lie down naturally. It’s a great solution for short or long trips, smaller cars, or when you need to free up trunk space.

Can I use a regular crate in the car?

Household crates or soft-sided carriers are not designed for car travel. They often lack secure anchoring points and have not been crash tested. For your dog’s safety, always use a dog crate for car travel that is made specifically for vehicles.

 

Do I need to secure the crate in the car?

Yes. Even if the crate fits snugly in your trunk, it should still be secured using straps or anchor points. An unsecured crate can shift in a crash or sharp turn.

 

Is it legal to transport a dog loose in the car?

Regulations vary by country or region, but many traffic safety authorities recommend or require dogs to be properly restrained. Using a dog car crate or harness is a safe and responsible choice — and in some cases, a legal one.
