How does the Thule Allax dog crate ensure safety during car travels with my dog?

The Thule Allax dog crate is crash tested and certified by TÜV SÜD, featuring an innovative crumple zone that offers superior protection for both your dog and passengers during rear-end, front collisions, and roll-over scenarios, ensuring safe journeys.

How do I select the right size of Thule Allax car dog crate for my dog and vehicle?

Choose a size that allows your dog to stand, turn around, and lie down comfortably. Refer to the size and weight guidelines in the sizing table, and size up if your dog falls between sizes.

What is the difference between the Standard, Compact, and Threshold Compatible versions?

The Standard version offers full depth suitable for deeper boots, while the Compact is a shorter-depth variant for shallower boots but with the same height, width, and capacity. The Threshold Compatible is designed for vehicles with a high boot sill, with a modified base to clear raised lips.

Can the Thule Allax dog crate be securely installed in my car?

Yes, the Thule Allax is secured using your vehicle’s existing cargo loop straps without drilling or permanent modifications. It is intended for installation in the boot of the car only.

How do I know if the Thule Allax dog crate will fit my vehicle?

Thule provides a vehicle compatibility checker on their website, and you can also message us with your car’s make, model, and year for personalized advice. Make sure to measure your boot depth and check compatibility before purchasing.

Is it safe to leave my dog unattended in the Thule Allax crate while traveling?

No, it’s not safe to leave your dog unattended in the crate. Always ensure proper ventilation, never leave your dog in the crate for extended periods, and supervise your pet during travel to ensure safety.

Thule Allax Car Dog Crate | Crash-Tested & Standard Compatible

Every journey, your dog rides safely. Crash-tested protection that fits your car, your dog, and your life.

The Thule Allax is built around one idea: if something goes wrong on the road, your dog should be as protected as everyone else in the car.

TÜV SÜD crash-tested to ECE R17 and ECE R129 standards, the Allax secures firmly to your vehicle's cargo loops — no drilling, no permanent modification. The depth-adjustable body means one crate covers a wide range of boot depths, and the gas-dampened door opens and closes quietly every time you load or unload.

What's the Difference? Standard, Compact & Threshold Compatible Explained

The Allax range includes three terms you'll see when choosing your size: Standard, Compact, and Threshold Compatible. The table below summarises exactly what each one means.

Standard

Allax Standard

The full-depth version. Available XS–XXL. Suits vehicles with a deeper boot — estate cars, large SUVs and MPVs. If your boot has plenty of depth front to back, go Standard.

Compact

Allax Compact

Not a separate product — a shorter-depth variant of the Standard at the same size. Same height, width and dog capacity. Designed for vehicles with a shallower boot. Available at sizes M, L, XL and XXL within the Standard range.

Threshold Compatible

Allax Threshold Compatible

For vehicles with a high boot sill. Modified base clears the raised lip without scraping. Available in XS, S, M Compact, M and L Compact only. Slightly heavier than the Standard equivalent.

Not sure which variant fits your car? Measure the height of your boot sill (the lip at the rear of your car when the boot is open). If it's above roughly 15–20cm, the Threshold Compatible is worth considering. Still unsure? Message us on WhatsApp.

Sizing Guide

Choose your size based on your dog's weight and your vehicle's boot depth. Your dog should be able to stand, turn around and lie down comfortably. If your dog is between sizes, size up.
