Comfort and safety for your dogs on the road
The Thule Allax double dog crate is the perfect choice for safe and comfortable car rides with your four-legged friends. Designed for flexibility, it can be used for two dogs or converted into a spacious crate for one larger dog by removing the parting wall. The adjustable wall can also be angled to create more space on one side, making it ideal for dogs of different sizes.

The gas-dampened door opens and closes softly, and the built-in lock adds extra security.

Size guide
What size crate for your dog?
Choosing the right size dog crate is important for your dog's comfort, safety, and well-being during travel. The crate should allow your dog to sit, stand, turn around, and lie down in a natural position. However, it shouldn't be so large that your dog slides or is tossed around during travel, as this can lead to discomfort or injury.
Every dog is different—use the guidance here as a starting point, but ultimately, you know your dog best. Consider their comfort, habits, and how they travel. Also, make sure to follow any local recommendations regarding pet travel.
How to 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).

Not sure if the crate will fit? Here's how to check:
1. Depth:
Measure from the back of your rear seats to the end of the trunk floor. If you have a hatchback or SUV, also check where the trunk door starts to slope in.
2. Height:
Measure from the trunk floor to the lowest point of the door, hatch, or ceiling. Watch out for low-hanging edges that could block the crate.

3. Threshold height:
Does your trunk have a raised edge (threshold)? Thule Allax fits thresholds up to 40 mm.

Thule Allax threshold compatible fits thresholds over 40 mm (up to 170 mm for XS, 245 mm for S, M compact, M, L compact).
