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.

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).
